So reading the following out of a scanner, which one cause the SES to come on?



[PCM] P0101 - Mass Air Flow (MAF) Sensor Performance (Old) (Immature)
[PCM] P0102 - Mass Air Flow (MAF) Sensor Circuit Low Frequency (SES) (Pending) (Old) (History) (Current) (Immature)
[PCM] P0172 - Fuel Trim System Rich Bank 1 (Old) (Immature)
[PCM] P0175 - Fuel Trim System Rich Bank 2 (Old) (Immature)
[PCM] P0412 - Secondary Air Injection (AIR) Solenoid Relay Control Circuit Bank 1 (SES) (Pending) (Old) (History) (Current) (Immature)
[PCM] P0418 - Secondary Air Injection (AIR) Pump Relay Control Circuit Bank 1 (SES) (Pending) (Old) (History) (Current) (Immature)
[PCM] P0443 - EVAP Purge Solenoid Valve 1 Control CKT (SES) (Pending) (Old) (History) (Current) (Immature)
[Entertainment] B1327 - Device Power Circuit Low (History) (Immature)
[Entertainment] B1004 - Keep Alive Memory (KAM) (History) (Immature)
[Entertainment] U1255 - Class 2 Communication Malfunction (History) (Current) (Immature)

I would start by looking at the status of the codes. The only codes showing current are P0102, P0412, P0418, and P0443.

Are you having driveablility issues?

nope i got the car back from GM after hours for fixing my heated seat and checking noise out of the steering while. i start my car with SES on so no idea what they did

??? They are all "old" Can't believe they didn't reset the codes when they had it. You really need to have it reset and start from scratch. Almost all say they set of the SES.

the dealer ship here makes me hate my car so much!
i cant remember the last time i had my car for more than 2 weeks straight

DEFIANTLY reset your SES light and see if they pop back up then get worried!

Sam.... did you ever get all of this resolved??? In another thread before this SES issue you had the Mortor Mount and some other parts replaced and mentioned a gas milage issue.....
All of that leads to issues I have been experiencing for oh about 13 months... I am too lazy to pay 1000 for the 3 o2 sensors and the exhaust, but when my cat went, the o2 sensors followed, and the Maf was next.....
try taking the Maf out and spraying it with some cleaner and putting it back in, also look for a vacuum leak... if your CEL isnt on and the cat isnt coding, then the fuel milage is an intake issue(maf), or a leak in the exhuast or vacuum.... normally the fuel lean codes will set off the CEL though if it was any of those problems......
let us know if the dealership ever figured it out...most dealers dont know sqat about the northstars.....

Well i think these codes are the least of that cars worries as it got totaled by some jerk in a 300c.
