This should be one inch to the right of your oil filter bolted into the engine block. I have to replace mine too. Its about $70 at rockauto.com. My CKP is leaking oil right thru its ring. I believe you'll have to let the oil out first. Might as well change the oil and filter. It also looks like it's just taking it out and putting a new one. The wire harnes goes from the the side of the block(sensor) and up towards the back of the engine. I still have to look into it to find out what size/kind of bolt it has.

I have a problem with my 98 Catera. It just dies after up to temp. after a while it will start again, but not for at least 20 min. Is that the troubles you had with your CPS?

Vaya Boricua.., no problem!!! Trujillo Alto in the house!

Hey, you just gave me an excellent idea. I never thought of just cleaning the damn thing :thumbsup: !!!!!!!! I'll do that till I can get it fixed! I can't find the connector for this sensor. It's somewhere tight behind the engine!!

I'm not sure of one thing though. The Crankshat Pos Sensor may require an additional 'O' ring in the block, but.. im not sure about that yet!

Hopefully someone :angel: in the forum may clarify these things for us!

Yep!!

That's what I have on the manual! It says that the best way to get at it is by removing the wipers, the molding they are mounted on and the wiper motor!! Huh!! didn't really want to do that..., but I guess that's what I'll have to do..!!

Where's an EASY button when you need one.:bonkers: .

Thanks for your quick response Omer.;) !!!!

Bien.., Bien.. Pa' la playa ya mismo!!

Hey, I found the Crankshaft Pos Sensor connector!! :bouncy: Eureka!!!

Just follow the procedures to remove the wiper vents. This is the plastic right below the wipers. The plastic has a "T30" type screw, if im not mistaken, on the lower left side of it (driver side).

Once that's done remove the wiper arms with a 1/2" socket, put some WD-40 on the bolts, wait a little, then rock the arms back and forth. They'll come right off.

Once that's done there is a rubber seam that's kinda attached to the windshield. The plastic vent cover's edge hides right under that rubber. Uncover the rubber and you'll see "flat/phillip" head type screws, remove those.

The plastic comes right out. It is segmented so.., only a little more than half of it will separate from the windshield. Once removed you'll find much more space to look and get behind the engine.

The sensor is connected to one of the corrugated plastic ducting covered wires that come out of the black plastic rail that sits right above the spark plugs. Look at the end of this black plastic rail going towards the back of the engine. There should be like 4 corrugated plastic ducting comming out of it at the back. The "CPS" wire should be one of the lower small diameter ones.

Once you start wiggling stuff arround you'll see the conenctor. Well, in my case I did see it right away. If for some reason you still have the original mounting fixture there it may still be attached to something back there and you wont immediately see it! Also, there should be a big connector with visible wires in front of the "CPS" connecting wires, there by hiding it too.

In any event the CPS connector should be some where right above the ignition coil. It makes and "S" on it way down to the sensor and it's caught by the oil cooler lines.

To remove mines I'll cut the connector off and just pull the wire down from the sensor side. To put it back just re-route it some where safe, away from the hot manifold, on the left side of the engine only.

Hope you'll see it right away.

** RE-POST **

Actually, the best way of getting rid of the bad sensor is to cut off the sensor side of the cable then pull the wire from the connector side. The oil cooler lines are closer to the bottom and pinch the "crankshaft sensor" wire closer to the bottom. Before cutting the sensor side off, first wiggle the cable with some force (from under the engine) so that it loosens up a bit from the its heat protecting metal sheath that it comes with. Also try to straigthen out the cable as much as posible so as to minimise friction at the kink points.

Once that's done, just cut the sensor side off and pull the wire from above the engine with some force and it'll come off.

I re-routed the my sensor on the left side of the engine only. Make sure you use a path that will definitelly keep the wire away from the hot motor manifold.
