Code P2135 2005 Toyota Prius Description
The P2135 diagnostic trouble code (DTC) for a 2005 Toyota Prius indicates a problem with the Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation. This code specifically relates to the correlation between 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 driver's desired throttle position and communicate this information to the engine control module (ECM).
Common Causes of P2135 2005 Toyota Prius
- Faulty throttle position sensor
- Faulty pedal position sensor
- Damaged wiring or connectors in the throttle control circuit
- ECM software or hardware issues
- Corrosion or contamination in sensor connections
Symptoms of P2135 2005 Toyota Prius
- Erratic throttle response
- Poor acceleration
- Stalling or engine hesitation
- Limp mode activation
- Check Engine Light illuminated
How to Fix P2135 2005 Toyota Prius
- Perform a thorough inspection of the throttle position sensor, pedal position sensor, and related wiring for any visible damage or corrosion.
- Use a multimeter to test the voltage output of the TPS and PPS to verify if they are within the manufacturer's specified range.
- If either sensor is found to be faulty, replace it with a new OEM part to ensure proper functionality.
- Clear the DTC codes from the ECM using a scan tool and perform a test drive to confirm that the issue has been resolved.
- If the problem persists, further diagnosis may be needed to check for ECM issues or wiring harness faults.
Cost to Fix P2135 2005 Toyota Prius
The typical repair costs for addressing a P2135 code in a 2005 Toyota Prius can range from $200 to $500, including parts and labor.
