Code P2135 2005 Toyota Highlander Description
The P2135 diagnostic trouble code (DTC) for a 2005 Toyota Highlander indicates a problem with the Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation. This means that there is a discrepancy between the voltage signals being sent by the throttle position sensor (TPS) and the pedal position sensor (PPS) in the vehicle's electronic throttle control system. The TPS and PPS work together to determine the throttle position and relay this information to the engine control module (ECM) to adjust the air-fuel mixture for optimal performance.
Common Causes of P2135 2005 Toyota Highlander
- Faulty throttle position sensor
- Faulty pedal position sensor
- Wiring/connectivity issues
- ECM malfunction
- Corrosion or damage to sensor connectors
