Help With Cel!

bigd1 · 04-17-2008, 11:33 PM

My had the CEL come on Tuesday. Took it to Autozone to check the codes and I had two. I have a P0031 code Heater Circuit Low (bank1) (sensor 1). and a P0171 System Too Lean. I reset the codes but they came back tonite. My STI is a 06 with all the bolt-ons and Ecutek tuning. It has 31,854 miles and I've never had a Cel. The Autozone clerk said it was my front O2 sensor. Is this possible? Will my warranty cover it considering the mods? Thanks guys. Any input would be appreciated.

might help to actually list your mods instead of "all the bolt-ons"

Injen CAI, TURBO XS UP PIPE AND DOWN PIPE, HKS POWER EXHAUST, HKS HEADERS, HKS BOV, AND PERRIN PULLEY.

Are you tuned for those mods? I'm betting the CAI and BOV are causing the lean condition

dead front 02. My front o2 is dead, well it works sporadically, and I got those same codes. I also got the front o2 slow response code. I can not see the dealership covering it because you have headers. Maybe if you still had the stock manifolds on there. I think they are about 150 bucks online.

Yes it is tuned for the mods.

well if the autozone guy said its the front 02 sensor and rjacobs says its the fron 02 then maybe its the front o2 sensor?

had the same problem as well, and yes its the main o2 sensor, primary wide band o2 sensor.

Is there any websites that you guys recommened where i could get the sensor cheaper than the 215.00 bucks Autozone is asking for?
