Causes and Fixes P0132 Code: Oxygen Sensor Circuit High Voltage (Bank 1, Sensor 1)

How to fix P0132 Code: Oxygen Sensor Circuit High Voltage (Bank 1, Sensor 1) The oxygen sensors measure the oxygen content in the exhaust gases after they leave the combustion process of the engine. They also monitor the catalytic converter. A P0132 Code is set when the computer (ECM/PCM) determines that the oxygen sensor voltage remained above 450 millivolts for more than twenty seconds (varies with vehicle make and model) or that the air fuel ratio sensor remained in a rich-biased mode for too long (varies with vehicle make and model). Causes of a P0132 code include a bad oxygen sensor, wiring issues, exhaust leaks, rich condition, and computer issues. If the engine is running rich, it can be hard to diagnose. Possible Causes of a P0132 Code: Bad Bank 1 Sensor 1 Oxygen Sensor 02 Sensor Wiring issue Exhaust Leaks Rich Condition (Bad Injector, Bad Sensor, Blocked Airflow) By using this information user assumes all risk of use.
