Code P2620 Description
The P2620 code indicates a problem with the throttle position output circuit, specifically an open circuit. The throttle position sensor (TPS) is responsible for monitoring the position of the throttle valve and sending this information to the engine control module (ECM). When the ECM detects an open circuit in the throttle position output circuit, it means that there is a disruption in the communication between the TPS and the ECM. This can lead to incorrect fuel injection, improper transmission shifting, and overall poor engine performance.
Common Causes of P2620
- Faulty throttle position sensor
- Damaged wiring or connectors in the throttle position output circuit
- Corrosion on electrical connections
- Malfunctioning engine control module (ECM)
- Poor electrical grounds
Symptoms of P2620
- Check Engine Light is illuminated
- Engine hesitates or stumbles during acceleration
- Rough idling or surging
- Reduced fuel efficiency
- Transmission shifting issues
How to Fix P2620
- Begin by using an OBD-II scanner to confirm the P2620 code and diagnose the exact cause of the issue.
- Inspect the throttle position sensor, wiring, and connectors for any visible damage or corrosion. Replace any damaged components.
- Test the throttle position sensor using a multimeter to ensure it is functioning properly.
- Check the engine control module for any faults and replace if necessary.
- Clear the error code from the ECM and test the vehicle to ensure the issue has been resolved.
Cost to Fix P2620
The typical repair costs for a P2620 code can vary depending on the specific cause of the issue.
