Code P2239 2006 Toyota Camry Description
The P2239 diagnostic trouble code (DTC) for a 2006 Toyota Camry indicates a problem with the Oxygen A/F (Air/Fuel) Sensor Pumping Current Circuit High on Bank 1 Sensor 1. This sensor is responsible for monitoring the oxygen content in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the pumping current circuit is reading high, it means that the sensor is sending a signal indicating a rich air-fuel mixture.
Common Causes of P2239 2006 Toyota Camry
- Faulty Oxygen A/F Sensor
- Wiring or connector issues in the sensor circuit
- Exhaust leaks near the sensor
- Engine misfires
- ECM software issues
