I am getting the following check engine codes:

P0069--map/barometric correlation
P0068--maf/map sensor throttle position correlation
P2228--barometric circuit low

Car was working great til up til now. I was driving along with cruise set at 60 when my car went into reduced power mode.

I pulled over & unplugged the sensor near the oil filter cap. I did an oil change 3 weeks ago and I was think maybe I some how disconnected it. Unplugged and replugged the connecter. Car started up but CEL was on. Drove it to work just fine. Get out off work at 5:30 and about half way home it did it again.

My mods include: GM stage II, Injen CAI, GMPP exhaust. Those items have been on for over 2+ years. I have about 104k on the car.

Any ideas on what might be going on or could point me in the right direction? Much rather not go the Stealership...

Thanks!!

 

Yeah it sounds like you pulled a wire loose that you shouldn't have.

 

I see the word barometric, which would relate that code in some way to the sensor on the top of the blower.

 

That's the one that usually gets disconnected (at least I disconnect it) when doing an oil change. Either way, check the connection and make sure it's tight.

 

surprised you didn't get engine power reduce! these are the codes that popped up for me when I got it, all my wires were good though. I just cleaned them up and re-did em'.
