Code P2240 2007 Toyota Camry Description
The P2240 diagnostic trouble code (DTC) for a 2007 Toyota Camry refers to an issue with the Oxygen A/F Sensor Pumping Current Circuit Open on Bank 2 Sensor 1. This specific sensor is responsible for measuring the oxygen content in the exhaust gases and providing feedback to the engine control module (ECM) for optimal air-fuel mixture control. The ECM uses this information to adjust the fuel injection and ignition timing to ensure efficient combustion and reduce emissions.
Common Causes of P2240 2007 Toyota Camry
- Damaged oxygen sensor
- Corroded wiring or connectors
- Blown fuse
- Faulty ECM
- Exhaust leak near sensor
Symptoms of P2240 2007 Toyota Camry
- Decreased fuel efficiency
- Rough idling or stalling
- Engine hesitation or misfire
- Check Engine Light illuminated
- Increased emissions
