Sensor Circuit High Voltage. If the voltage is steadily high 9v or higher the o2 sensor may be faulty. Before replacing check the following.
If damaged repair or replace affected harness. More specifically if the pcm monitors that the o2 oxygen sensor voltage is above 450 millivolts for more than twenty seconds error code p0132 will be triggered. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
To get a better grasp of the meaning of this code you must first understand what an oxygen sensor is.
Before replacing check the following. P0132 is a diagnostic trouble code dtc for o2 sensor circuit high voltage bank 1 sensor 1. Check the wiring at o2 sensor for damage. Diagnostic trouble code dtc p0138 stands for o2 sensor circuit high voltage bank 1 sensor 2.
