As the title states, a 2001 Cadillac Seville SLS will not start on it's own and is tossing an error code P0106. It will start and run as long as I have my foot on the gas pedal.

At any rate, this started right after I replace the plugs, coil packs, and AIR FILTER. I'm thinking that I may have bumped the Air Mass Sensor, I see a little rub mark on it. Do you guys think this may be my problem or have another suggestion for me?

Re: 2001 Cadillac Seville error code P0106

That pic is a mass air flow sensor, That rub mark is not the problem, I have a couple on mine and no problem.

p0106-Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance
That code is the map sensor code.

 

[RobertDIY]

So, where is that? How do I deal with it or fix it? Is it usually a wiring issue or a bad sensor?

replace the MAP sensor as well as the PCV and o-rings problem solved trust me and get ac delco

Robert, Copy this and put it in your car file.

"Where is this ?" .............................. MAP (Manifold Absolute Pressure)(the inverse of vacuum) sensor. Retained by the tang on the throttle cable bracket. It's a push-in pull-out item. Check the electrical connector and wiring first.

That screen is just an air flow straightener and as northstarfuel said, it is of no consequence.

Guys, thanks a lot. I really appreciate the help.

Where is the PCV and what o-rings should be replaced?

 

[Submariner409]

Your engine may not have a PCV in the old, rattle valve, sense. In the 2000s they went to a fixed orifice.

It's in the inner side of the right (rear) cam cover - a fitting with 1/2" hose/pipe that runs around into the intake manifold at the front (passenger) end. Remove the engine cover and carefully pull the rubber connector off the valve/orifice nipple. If you have a PCV valve (removable) it can be cleaned with choke cleaner while out of the car. If the system uses the newer orifice there's no cleaning to be done............. BUT an air (vacuum) leak in that dirty air hose/pipe/connectors will set codes as well as cause driveability problems.

No idea which O-rings he's referencing.

Ok, I did see that hose and end when I installed the rear bank coil pack assembly. I thought that was it but wanted to be sure.

This morning the car fires up and runs like a champ. So the MAP is intermittent. I will replace it this morning and hopefully the car will run well for a few months.

It has the P0481 code and the gas gauge shows FULL all of the time. I have not been able to get the car to warm up above 220 degrees to see if any of the fans will kick on and the AC doesn't work so that doesn't turn them on. One thing at a time I guess.

===========================

you should get into the habit of including CODE DEFINITIONS
along with any codes that you post -

someone who hasn't memorized all the codes will either stop -
and go look up the definitions -
or just bypass your thread -

I replaced the MAP sensor and the car continued to drive well. After driving for 30 minutes it started stalling when coming to a stop. I could see the idle drooping around 500 rpms and then stall. It will restart if I give it gas. I can also keep it running with the accelerator pedal. I guess I'll try to clean or replace the PCV valve and see if that helps.

clean the TB - Throttle Body - and IAC - Idle Air Control solenoid -

:yeah:

 

[RobertDIY]

Cleaned the IAC and throttle body about a week ago and things have been going great... until last night. Darn coolant hose burst and she drove until the car overheated. SMH

Thank you guys again for the help and support. I'll see if the engine is damaged and post back.

 

[Ranger]

Shouldn't be any damage. The engine was designed to run for 50 miles with no coolant.

This is new to me, but just what does replacing the resonator with a "butt plug" supposed to do? I can't imagine creating new harmonics with a plug could be of any benefit over the factory-designed installation.

 

[Submariner409]

You don't create any new "harmonics". You make your weekly underhood fluids checks a LOT easier as well as make air filter changes a 5 minute job.

Post #5 for those that read entire threads.

 

[Mgilla]

Well, I read the entire thread - even saved the component pic, which is where I saw the "butt plug" being used. I'd heard of this modification before, but couldn't understand why it was being used - other than, as you pointed out, the ease of which one could make filter changes. It just seemed that it would throw off its intended usage.

 

[MoistCabbage]

All the resonator does is quiet intake noise. Mine is long gone, and to be honest, even before the Corsa, I couldn't hear any additional noise with a plug installed.

There is zero downside, and much better access.

 

[Ranger]

All the resonator does is quiet intake noise.

I'm not even sure it was very effective at that.
