p0132 bank 1 sensor 1 issues
05 xlt 4x4 20,000 miles on reman.ran obd-ii code scanner and code p0132 keeps popping up. changed bank 1 sensor 1, cleared code, ran for a while thehn code popped back up. took the sensor out replaced it with another one and still same issue. took truck to the exhaust shop and had them replace passenger side cat because it was stopped up. replaced maf sensor and truck ran like brand new. code was cleared for about 30 minutes. started the truck up this morning and code has popped back up again. searched through a bunch of forums saying chase the wires there might be a short in the circuit. was wondering how to chase from the ecm back to the sensor.

All you need is a DMM set on continuity and find the pin out of the ECM harness (or pin out of a module it might plug into, before going to the ECM) then check for continuity while moving the wires around.

ok so I pulled the female connector to bank 1 sensor 1 to the top, cleaned it with some contact cleaner, then proceeded with the voltage test. put one multimeter lead to connector 29 and the other to the signal in pin on the male connector and it had continuity, so that told me there was no short. I sprayed a little contact cleaner into the plug that connects to the computer and code went away. no cel, ran the scanner on it again and a residual po2195 code popped up but again there is no cel light, so I'm thinking when I took the air filter off and let it run to see if the rpms would drop might have kicked the code over, but once I put the filter back in the code never reoccurred. I'm still having idle issues but not much. will give an update in the next few days as to my progress.
