crankshaft positioning sensor. Very common problem. About a $150.00

Is that why the car is shutting off or is that going to be for the oxygen sensor????

Could be. I've never had an O2 shut down a car. CPS is a very common problem.

It's not the o2 sensors.

Take the car to AutoZone and have the codes pulled. Replacing anything before that is just guessing.

It's most likely the crankshaft position sensor and cost about $45 to $50. I had a similar problem about 6 months ago and replaced it and so far no problems. The sensor is located right by the oil filter and the other end goes all the way to the top behind the upper intake (driver's side).

Yes, it's pretty easy fix and I would say about an hour all together. You may have to cut the old wire where it gets pinched by the oil cooler lines and send the new one around it. Also, add extra aluminium foil (extra heat shield) around the new wire where it gets close to the exhaust pipe.

08-21-13, 10:48 PM
Well here are the parts she need's to buy.... and please let me know if they are the wrong parts

1. 2 O2 sensors they are
Bosch - Oxygen Sensor
Part # 16065

2.CranKshaft Position sensor
BWD - Crankshaft Position/Angle Sensor
Part # CSS79

3.Speed Sensor.... now we are lost with this one is there a difference between an ABS Speed Sensor and a Speed Control Sensor????

and each part was found at O'Reilly Auto Parts on O'Reillyautoparts.com

MoistCabbage
08-22-13, 06:23 PM
There is a speed sensor for each wheel (wheel speed sensors), and a vehicle speed sensor (for PCM and speedometer). No such thing as a "speed control sensor".

How do you know the O2 sensors need to be replaced? How do you know there's a speed sensor problem?

Were the codes pulled???

Which codes came up?

I didn't pull any codes her dad did and he stated that the O2 sensors need to be replaced, which I think they might need to be cleaned. I know from the jump that she need with the Crankshaft Position/Angle Sensor because from what I seen it will drive about 3 miles and shut right off..

Pictures of what has to be removed are in the thread.

If he's wondering what the sensor looks like, just look at the new one. I assume he'll have it when he starts the job. Or find the part online, there are usually pictures.

If he's wondering exactly where it is, follow the wire pictured in the thread. It's visible from under the car, near the oil filter. Held on with one bolt.

There's a diagram here, but not very good:

probably he misplaced something or maybe some wire is not connected.

Another possibility might be bad coils or have to relearn throttle body in case he removed it or maybe a vacuum leak somewhere.

also, try unplugging the Mass airflow sensor and see what it does. It could be a MAS sensor too.

Sounds more like a fuel filter. Not really enough information. Does it start right back up or do you have to wait a few minutes ? Instant shut off or does it sputter first ? I have not seen an O2 sensor shut one down 3 miles after starting. Usually you notice it runs rough, drinks gas, or a couple of other things, but usually not a shut down problem.
As for it being a battery, does it go dead ? Lights still work ? still turn over ? Need to know things like these to diagnose the problem.

Duralast parts are ABSOLUTE GARBAGE!

Don't bother with the multi electrode plugs, they're a gimmick. The spark can only jump to ONE at a time.

A fuel filter will not cause stalling after several minutes of driving.

If you're trying to fix this car cheap, throwing parts at it is NOT the way to do it.

Have the basics been checked when the problem occurs? Spark and fuel pressure?

AGAIN... What CODES is the car throwing?

I had a feeling duralast aren't good.

And no MC we are not just throwing parts at this car to be cheap, we are replacing parts that could be the issue. How we changed the CKS and placed a new battery in the car. We seen that the car was misfiring after we put the CKS and the battery, now could be the issue to the misfiring might be the spark plugs the coils. Which was pose to get done last weekend but the Florida weather stepped in and it didn't get done. So tomorrow he is placing the plugs and the coils , next weekend is the fuel pump if that still does nothing we are taking the car to Volkswagen dealer because of it being a German car and all.

We can't get the car anywhere if it's misfiring..

And no MC we are not just throwing parts at this car to be cheap, we are replacing parts that could be the issue.That is the definition of throwing parts at a problem. Replacing things that COULD be the problem.

Repairing is replacing parts that ARE the problem.


How we changed the CKS and placed a new battery in the car.If it needed a battery, it needed a battery, but there was no reason to replace the CKP sensor unless there was a code for it, or it tested bad.


We seen that the car was misfiring after we put the CKS and the battery, now could be the issue to the misfiring might be the spark plugs the coils. Which was pose to get done last weekend but the Florida weather stepped in and it didn't get done. So tomorrow he is placing the plugs and the coilsPlugs are a maintenence item, coils are not. Why are they being replaced, did they test bad? All of them? One? A few? Has anyone even checked which cylinder is misfiring?


next weekend is the fuel pumpWhat? Why? Was the fuel pressure tested? Is it low?


if that still does nothing we are taking the car to Volkswagen dealer because of it being a German car and all.The fact that a sister car of the Catera is sold under a German nameplate does not make the car German. Besides that, Opel is a GM owned company anyway, and the engine is built in England... Even if the car was German, taking it to a Volkswagen dealer accomplishes nothing. There are no German voodoo doctors in the shop, just techs, with experience working on, and shop manuals for cars that are completely different from a Catera.

So after this mechanic...no... After this parts changer replaces something, and it doesn't solve the problem, is he giving your friend their money back before he tries something else?

So here is an update from what I seen and know...

So the coils and plugs was changed, the coils and plugs that was in the car was bad I mean the worst.

So come to find out its the fuel pump that's not pumping, because we pumped gas into the cooperator it cranked right up for a few seconds and right back off. Now we just need a fuel pump and we have a running car, after that off to a shop for the basic fluid changes and the A/C service. That's till something else happens!!!

All of the debris in the 14 year old tank will get into the pump, lines, and injectors.

Un huh I see.. I have a question we are having someone replace the fuel pump, Our guy was going to charge us $80 but he is acting like an ass and he doesn't want to do the job anymore. So I have been looking around for an MOBILE MECHANIC and the two guys I have talked to so far want to charge us $200. One of the mechanic said this
"The labor cost to replace the Fuel pump would be $200. This is due to the fact that there's no easy access to the pump itself and the entire fuel tank needs to be dropped to get to it." Please tell me this is true because if it is we will go head and pay the $200 for the replacement if not we will go head and keep looking for someone else.

MoistCabbage
09-25-13, 03:30 AM
Well that wasn't offensive to anyone...



"Normal price" is whatever the hourly charge is, times however long the guy takes to do it.

Call a dealer and ask what the "book time" is to replace the pump (which is usually longer than the time it actually takes), and assume someone doing it without a lift is going to take longer.

$200 is just under 2 hours dealer time, which sounds about right to me, but you shouldn't be getting charged dealer money by a guy doing the work in a driveway.

It's cheaper than having to get it towed to a garage, so I wouldn't worry about it anyway. As long as the job is done right.

Cadillac Catera98
09-28-13, 03:15 PM
So here is an update you guys!!!!

The new fuel pump and filter is on the car. We pulled up two codes (P1141: Heated Oxygen Sensor (Bank 1 Sensor 2) Heater Circuit Malfunction & P0727: Engine Speed Signal Circuit Malfunction) But that is not the reason why the car is not starting, from what the guy told us the timing is off and he is sending someone out to rest the timing for us. more to come after we rest the timing.

MoistCabbage
09-29-13, 04:34 AM
The timing is off??? There is no distributor, timing is controlled by the PCM, and not adjustable. Did the "mobile mechanic" tell you this?

P0727 - Engine speed sensor? Anyone know if that refers to the CKP or CMP?

In many cars, the tach and ignition control rely on the CMP sensor. If the PCM has no reference of engine speed/position, it cannot provide spark. This can cause hard/no starting, and stalling.

..........As asked before... Is there spark?

Also, with no reference of engine speed, the fuel pump will only run briefly at key on, but not while cranking. You never answered my question about fuel pressure, so I'll assume nobody bothered checking it, but did anyone even check if the old pump ran at all before replacing it? Does the new one run?? At key on? While cranking?

I asked for codes over and over again. I hope for your sake that I'm wrong about what "engine speed sensor" is referring to, because if I'm right, that may have been the problem all along, and the codes would have told us in the beginning.

Cadillac Catera98

[QUOTE=MoistCabbage;11031041]The timing is off??? There is no distributor, timing is controlled by the PCM, and not adjustable. Did the "mobile mechanic" tell you this?

P0727 - Engine speed sensor? Anyone know if that refers to the CKP or CMP?

In many cars, the tach and ignition control rely on the CMP sensor. If the PCM has no reference of engine speed/position, it cannot provide spark. This can cause hard/no starting, and stalling.

..........As asked before... Is there spark?

So MC are you saying it could be a speed sensor???? or you are just stating?

There are several "speed sensors". It's not the vehicle or wheel speed sensors. The code has to be for either the CKP or CMP. There is no other "engine speed sensor" that I'm aware of.

Well it should be the CMP because we just replaced the CKP but then again it can be both, like you said once durlast parts are crap, & that is what we replaced the old CKP with....

Ok, I found some information on the code on a Saturn forum (similar drivetrain to the Catera).

The code is triggered when the TCM does not receive an engine speed signal from the ECM. That means either a communications issue between the ECM and TCM, or a problem with the CKP sensor, its wiring, or even a faulty ECM.

So... If it were a communications problem between the two modules, the engine would start and drive, but not shift right. A CKP/CKPs
wiring/ECM issue would cause no spark, and no fuel pump operation while cranking.

Check a couple of simple things, you don't need the mechanic:

- Remove the gas cap, and put your ear to the hole. Have a helper turn the key to ON. Do you hear the fuel pump run for a couple of seconds?

- Now have your helper try to start the car. Do you hear the pump running?

-Go to the parts store, and get a spark tester (~$5). Unplug a plug wire from a plug, plug on the tester, clamp it to something metal, have a helper try to start the car. Is there spark?

If there's no spark, and/or the fuel pump doesn't run, replace the DuraCRAP CKP with an AC/Delco one.

Here is an update on my issue..

From unpluging the computer a lot can mess things up and not giving the car enough communications to do anything...'

MC you are right there was an communications issue with the ECM & not it has to be replace our guy said he's going to look to see what he can find and go from there..

Unplugging the ECU multiple times won't hurt anything. ...More "info" from the portable "mechanic"?

That doesn't mean it's not defective, but before you replace it, check and clean the pins on the connector and the ECU, and check the appropriate wires for continuity.

He did all that, he unplug everything first then cleaned everything... I sat and watch him do everything, he used his truck to try and rest everything took 15mins and that still didn't do anything. Went back and checked everything so the EMC is an issue for now....

Use his truck to reset something? What?


Anyway. I believe the replacement ECU will have to be programmed to the VIN with a TECH II. Unless you buy one that has been cleared of the previous VIN.

Before he left, he took down the vin as well as the information on the driver-side door with him to look for a ECU. So hopping he finds something if not we might have to buy a new ECU.

What do you think of Cardone Auto parts, I'm asking because that is the part at Advance auto parts and where the company credit line is with...

Cardone - Depends what kind of part. For the most part, they're good.

There's no such thing as an aftermarket ECM though.

This sounds strikingly similar to what happened to my Catera back in April. Honestly, I never looked into it because I just gave up with the car. I would drive it for 15 minutes then it would just stall/shut off. After half an hour I'd be able to start it again, and the same thing happens. Then, while sitting it developed a misfire in cylinder 6 which, I'm guessing, is from bad gas.

"Bad gas" is excruciatingly hard to find.

Old gas.

If it were old enough to cause a problem, it would be consistent. Not come and go in 15 minute/half hour intervals.

Ahhhh dude, I meant the misfire developed a few months ago while sitting. I haven't put in any gas since April, and I'm saying that the misfire may be from months old gas. It has nothing to do with the stalling/shutting off of the car.

It takes many years for gas to go bad. I have a car in storage that I just took out for the every 2 year emissions inspection. Looking at my records I see I last filled it up in 2006. So with 7 year old gas it still runs fine.

Im not a pro. but 7 years ago a would say gas was different. Alot of chemicals companies started to add to the gas in pass 7 years, to minimize oil in gas so they can produce more to sell. Now gas have expiration date....

.....What? What oil in gas? Where did you get that little tidbit of information???

Anyway.. In 2003, my '91 Accord was totaled. It sat in a friends yard until 2 years ago, at which point I moved it to a garage on my street. It started right up after 8 years of sitting, with the same gas in the tank, and no stabilizer.

A couple of years ago, my Seville was not drivable for 364 days. After the engine was replaced, it started and ran fine on the whole half tank of year old gas.

Gas that is several months old, is perfectly usable.

Hi to all,

I haven't been on the forums for about a month now, because a little something in the family issue all of your help has still been useful & I have been using it to the best of my knowledge.

But here is a little update & hopping I can have an incite of what to do, come to find out it was never the fuel pump is was the computer to the car which had burned out jumping the car with a dead battery so I was told.
