Faulty Oxygen Sensor
A faulty oxygen sensor is one of the most common causes of a P2231 Code. This can be either the sensor before or after the catalytic converter. If the oxygen sensor is not working correctly, it cannot accurately measure the oxygen content in the exhaust. This will cause the O2S circuit to register a malfunction and trigger the P2231 Code. To fix this issue, you will need to replace the oxygen sensor.
Faulty Oxygen Sensor Heater
Another common cause of the P2231 Code is a faulty oxygen sensor heater. The oxygen sensor heater is responsible for keeping the oxygen sensor at an optimal temperature for accurate readings. If the heater is not functioning correctly, it can cause the O2S circuit to trigger the P2231 Code. You will need to replace the oxygen sensor heater to fix this issue.
Circuit Wiring Issues
The O2S circuit wiring can also be a cause of the P2231 Code. If the wiring is shorted or open, it can cause the O2S circuit to trigger the code. You will need to repair or replace the circuit wiring to fix this issue.
