Code P212D Description
The P212D diagnostic trouble code indicates that there is a high voltage condition in the throttle position sensor/switch 'G' circuit. The throttle position sensor (TPS) is a crucial component of the vehicle's electronic throttle control system, responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). The 'G' circuit specifically refers to a particular circuit within the TPS.
Common Causes of P212D
- Faulty throttle position sensor
- Corroded or damaged wiring in the TPS circuit
- Issues with the ECM
- Poor electrical connections
- Water or debris intrusion in the TPS circuit
Symptoms of P212D
- Erratic acceleration
- Poor fuel efficiency
- Engine stalling
- Check Engine Light illuminated
- Reduced engine power
How to Fix P212D
- Diagnose the issue by using a scan tool to read the code and perform a visual inspection of the TPS and related wiring.
- Test the throttle position sensor using a multimeter to check for proper voltage output.
- Inspect and repair any damaged wiring or connectors in the TPS circuit.
- Replace the throttle position sensor if it is found to be faulty.
- Clear the code and perform a test drive to ensure the issue has been resolved.
Cost to Fix P212D
The cost of repairing a P212D code can vary depending on the specific cause of the issue and the make and model of the vehicle. In general, replacing a throttle position sensor can cost between $100 and $300, including parts and labor. Additional costs may be incurred if there are other underlying issues that need to be addressed. It is recommended to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on the specific circumstances. Labor rates at auto repair shops typically range from $80 to $150 per hour, but can vary based on location and other factors.
