I have a P0106 code that will not go away. Here are the recent repairs that I have made:

New PCV valve with 2 new o-rings
New MAP sensor (from Advance)
New vacuum line fittings
Used carb cleaner to check for vac leaks, none found
New APN upper and new aluminum lower gaskets about 7,000 miles ago
New blue NAPA premium wires
New NGK 55 plugs
Cleaned MAF sensor with alcohol about 20,000 ago

Today I cleared the code, sprayed the MAP and MAF sensor plugs with electrical cleaner, cleaned the MAF with alcohol and the SES light stayed off for about 20 miles. Shut off engine and restarted and the light is back.

I suspect a bad MAF sensor. What do you think?

I think it would be best for you to cut/paste the actual text of the code from Techinfo to prevent having every one of us have to go look.

That is a MAP code, not a MAF.

Check to see if you get 1)ground 2)reference signal and 3)output signal at the pigtail.

I took a look at the list in "tech info" and P0106 was not listed.

Here is the information about this code that I located on another site.

"P0106 - Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem"

I am aware of this and that is why I replaced the MAP sensor as well as the PCV and o-rings as I suspected vacuum leaks around the MAP sensor housing. None found.

Actron OBDII scanner says:

"P0106 - MAP/BARO or MAF sensor condition
Possible causes
1. Vac hose off or passage blocked - Engine mechanical timing condition
2. Throttle body intake tube loose off or cracked
3. MAP defective
4. MAF sensor dirty or defective"

I cleaned MAF sensor and SES light stayed off for 20 miles and then came back.

Problem Solved

Would you mind telling us what it was?

Bad MAF sensor.

You have a PM.........

I have a 2013 Chevy Malibu, 2.4L ecotec engine. same thing happened to my car. It would hesitate, idle roughly, and stall sometimes. Every time this happened I received a "Service ESP" message on the dashboard and P0106 and P2227 codes. I replaced the MAP sensor, I replaced the Intake Manifold gaskets, I replaced the Throttle body gasket, replaced the air filter, replaced the MAF sensor, replaced spark plugs, and still the problem persisted. Finally, the problem was a clogged CAT converter and dirty O2 sensors. Adding 3 canisters of Wurth CAT/O2 cleaner to a full tank fixed the issue. Of course, you will need to go out on the highway and let it rip. Do that and let me know what happens to you car.
