So my check engine light is on blah blah blah...I went to advancedauto, hooked up the obd2 code reader, and it gave me P0136 (o2 sensor circuit malfunction, bank 1 sensor 2) ,P0138 (o2 sensor circuit high volts, bank 1 sensor 2), P0139 (o2 sensor CKT slow response, bank 1 sensor 2), P0141 (o2 sensor heater circuit malfuncttion) , and P1457 (manufacturer control auxillary emissions controls ). So i erase the codes and run my car for a little while, and the only code that comes up after that is the P0141 code.

So my questions are,

1.) Is bank 1 sensor 2 the upstream or downstream o2 sensor?

2.) Where do you recommend buying a new 02 sensor?

3.) The P0136, 0138, 0139, 0141 seem to be directly affected by the faulty 02 sensor, but what does the P1457 (manufacturer control auxillary emissions controls) mean?

thanks for your help
 

Billy.

sounds like your downstream o2 is shot (the one in your cat converter)

the 1457 code is a evap code.leak at canister area. check yur hoses at the charcoal canister.all the other codes are o2 related. hope this helps.

I can get you a direct fit o2 sensor for a decent price from Advanced Auto. LMK. Since your local it'll be easier
