I got a power train code 130 for a bank 1 O2. Where is it? Which one is bank 1?
beings you're saying you've got a j body that can give obd2 codes, i'll assume it's a third gen, and even further, a four cylinder car, so you only have one banl of cylinders, thus, bank 1. if this is the case, your bank1 oxygen sensor (as with all oxygen sensors), will be in the exhaust stream.
