Re: Stabilitrak/Traction Control Message

http://www.moderncamaro.com/forum/v6...mportance.html

Got the trio of messages on the way home last night, so I know the Mass air flow sensor is bad(1 week old). I got home and the water came pouring out. I did the modification, cleaned the throttle body, cleaned out the snorkel, and cleaned the MAF. I let them all sit disconnected overnight. I dried out the snorkel, dried the MAF , put it all back together and drove to work, in the high 20s. I got the Stabilitrack /Traction control messages and Check Engine light. I got to work, the MIL code was lean Bank a and B. I am going to Autozone for a new MAF. All indications were no milkshake in the snorkel but I will take it apart when I get to Autozone to swap the MAF. Keeping my fingers crossed here that this will solve all my (our) problems. Update at say 10pm.
Took the snorkel off to replace the MAF, and so far I could not find a hint of a milkshake, or moisture. So far so good, but I will not be celebrating until it passes the cold weather test. The next couple of days should tell. The PCV barb was clogged up good, I had to use a small drill bit to auger out the crud, I was able to see through it when I re installed it. BTW I just passes the 157,000 mile mark, hopefully another 157,000 to go.Online)

Re: Service traction control and stabiltrak and ck engine light

So far the modification is working. I found only one tiny drop of moisture in the snorkel, temperatures in the single digits and teens. I must have damaged the connector lock to the barb when I removed it, and it did pop off once. I got a rough idle and service stabilitrack, traction control, along with a new code, P0106. Manifold absolute pressure/BARO sensor Range/Performance. The tube was loose.
I went to the dealer and picked up a new one. The new one is insulated so I recommend replacing it when you do the Mod. $20.00..

2011 Enclave Stabilitrac Warning

My Wifes car will put up a warning message and ding a half dozen times every five minutes, car doesn't do anything else, no surging no change is the way it drives at all just the warning and dings. Only code in the computer is P0496 and that is an evaporative issue. Any ideas on what to check before going to the shop?

The Evap. issue is probably a bad purge valve. There are two on my 2008, one on the engine and one by the tank. Go to Rockauto to see if the 2011 has the one by the tank. The valve on the engine usually gives startup problems after filling up.
The one by the gas tank usually gives the P496 code.

Hold the phone, the P496 may be caused by the one on the engine. Do yourself a favor, buy that one, it is about $25. takes 10 minutes to change , and see if that makes your code go away. then take it from there. if it doesn't.

Also when my 2008 was giving me random stabilitrack, traction control messages I drove around for months before i brought it to a mechanic because i knew that they wouldn't be able to reproduce it. So several months later it was common to have the message, I brought it to my mechanic. He spent a good part of the day diagnosing and traced it down to the Mass air flow sensor. He tried cleaning it but it needed replacing since the road test came up with the messages again. This was also the first time the air intake snorkel was opened up to reveal a milkshake inside.
In my opinion it was this milkshake which caused the sensor to go bad.
Fast forward a year , messages reappeared, I replaced the MAF sensor remembering the problem before. But the source of the problem , the milkshake was not cured. I went through a couple months of He** till I found out about the PCV problem causing the milkshake and the cure for it.
Hopefully your issue is only the purge valve. But do open the air intake and clean your throttle body and let us know if you have a milkshake in there.

So, if I have service stabilitrak, traction control off, P0355 & P0356 cam positions A & B and a knock sensor issue.... I may not actually need a whole new engine? If I were to clean the catch can milkshake, replace the MAF, That it might be ok? Maybe I should do all that and take it to my local engine shop and see if the would replace the cam shaft seal, cams, reset them properly and timing chain. Then it might be WAY better than it is now.
