What does trouble code P0132 mean?
1 Answers
P0132 trouble code indicates high voltage in the oxygen sensor circuit (Bank 1, Sensor 1) (O2-Sensor-Circuit-High-Voltage(Bank-1, Sensor-1)). Possible causes include a short to positive in the oxygen sensor signal circuit, a faulty oxygen sensor, or a malfunction in the electronic control module (PCM or ECM). More details are as follows: 1. The oxygen sensor measures the oxygen content in the engine exhaust to adjust the fuel injection, ensuring the optimal air-fuel ratio for the engine. 2. The solution involves inspecting the wiring harness of the pre-catalytic converter oxygen sensor, replacing the pre-catalytic converter oxygen sensor, and updating the engine control module.
