[QUOTE="vr4, post: 4086501, member: 45270"] yes bank 1 sensor 1 is passenger side front sensor. it could be a number of things. heres the list from the PCED. this is for P2195 (stuck lean) but its the same idea. Electrical: Short to VPWR in harness or HO2S Water in harness connector Open/Shorted HO2S circuit Corrosion or poor mating terminals and wiring Damaged HO2S Damaged PCM Fuel System: Excessive fuel pressure Leaking/contaminated fuel injectors Leaking fuel pressure regulator Low fuel pressure or running out of fuel Vapor recovery system Induction System: Air leaks after the MAF Vacuum Leaks PCV system Improperly seated engine oil dipstick EGR System: Leaking gasket Stuck EGR valve Leaking diaphragm or EVR Base Engine: Oil overfill Cam timing Cylinder compression Exhaust leaks before or near the HO2S(s) [/QUOTE]
