...oxygen sensor on bank 1 decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust ...
...Shorted oxygen sensor circuits have been known to wreak all kinds of havoc with the powertrain control module. It could be the oxygen sensor itself, but be sure to check the oxygen sensor wires to ...
...oxygen sensor, you need to check the wiring that goes to the oxygen sensor, and check your fuses, and relays, some fuses and relays are under the hood located in a black box, on the drivers side, and ...

...following has happened: The oxygen sensor heater circuit is shorted out The wiring to the sensor is broken / frayed (less likely) Possible that the wire is bad some where , was that on my wife's ...
...oxygen sensor. Check for the following conditions:A rich exhaust - An overly rich exhaust may load the catalytic converter causing high rear HO2S 2 signal voltages.A silicone contamination - A ...
...oxygen sensor), but that falls way short of a decent description. I think fuse 11 is transmission control module, powertrain control module, automatic shutdown relay, fuel pump relay.. most likely it ...
shorted condition detected in the transmission 2-4 shift solenoid circuit (4-speed auto. trans. only).P0136 (M) 1/2 O2 Sensor Heater Circuit Malfunction Oxygen sensor heater element malfunction. Aside
...oxygen) sensor #1 on bank 2 (the side of the engine that doesn't contain cylinder #1). Great SUV, I too have one '93 GC Limited; this 51 mean "O2S Stays Below Center (lean air/fuel ratio). O2S input ...
oxygen voltage reading is .9 volts or high, the PCM interprets this as a rich condition in the exhaust and as a result decreases the amount of fuel entering the engine by shortening injector "on time"
oxygen sensor (HO2S) 1, bank 2 - high voltage Possible causes: Wiring short to positive, HO2S, ECM P0157 Heated oxygen sensor (HO2S) 2, bank 2 - low voltage Possible causes: Exhaust leak, wiring short
