i have searched and read the 4 or so threads about this code. There was not enough iformation on how to fix the problem longer term, just quick fixes like change maf and turn off CEL. i was wondering if anyone knows what is really really the problem. thanks.

 

P2A03 A/F Sensor 1 Bank 2 Circuit Range/Performance

Check for exhaust issues and if still an issue you might try replacing the sensor

It'll relearn.

 

thank you kind sir!

 

im about to jack up the car and check. hope its a leak so i dont have to spend money on a a/f sensor.

 

its been 500 plus miles. i dont understand whats going on. i reset the CEL thats it. the cel just came back on. so what should i do now...

 

I'm pretty sure that there are no known solutions right now. I ended up just getting the CEL turned off with UpRev, sorry man this code's a b!tch.

 

lol. ok where do u go for an uprev tune. forged?

 

Yeah, I got a tune there a while back so it only took a minute or two for Sharif to hook up his laptop and turn the little gremlin off haha!
