Code P2621 Description
The P2621 code indicates that there is a low voltage condition in the throttle position output 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 voltage in the output circuit is lower than expected, it can cause issues with the vehicle's performance, including rough idling, poor acceleration, and potentially even stalling. This code typically triggers the Check Engine Light on the dashboard. If left unaddressed, it can lead to further damage to the engine and other related systems.
Common Causes of P2621
- Faulty throttle position sensor
- Corroded or damaged wiring in the throttle position output circuit
- Issues with the ECM
- Loose or poor electrical connections
- Water or debris intrusion in the throttle position sensor
Symptoms of P2621
- Check Engine Light illuminated
- Rough idling or engine stalling
- Lack of power or poor acceleration
- Difficulty shifting gears
- Reduced fuel efficiency
How to Fix P2621
- Use a diagnostic scanner to read and clear the code
- Inspect the throttle position sensor and wiring for any damage or corrosion
- Replace the throttle position sensor if faulty
- Repair any damaged wiring or connectors
