Code P2137 Description
The P2137 diagnostic trouble code (DTC) refers to an issue with the Throttle/Pedal Position Sensor/Switch 'B'/'C' voltage correlation. This code indicates that there is a discrepancy between the voltage signals being sent by the throttle position sensor and the pedal position sensor, which are crucial components in the vehicle's electronic throttle control system. The throttle position sensor measures the angle of the throttle plate, while the pedal position sensor detects the position of the accelerator pedal. When these sensors do not correlate properly, it can lead to a variety of performance issues and potentially unsafe driving conditions.
Common Causes of P2137
- Faulty throttle position sensor
- Faulty pedal position sensor
- Damaged wiring or connectors
- ECM software issues
- Environmental factors (moisture, corrosion)
Symptoms of P2137
- Reduced engine power
- Acceleration hesitation
- Rough idling or stalling
- Limp mode activation
- Check Engine Light illuminated
How to Fix P2137
- Diagnose the issue using a scan tool to confirm the P2137 code and identify the specific sensor causing the problem.
- Inspect the throttle position sensor, pedal position sensor, wiring harnesses, and connectors for any visible damage or corrosion.
- Test the sensors using a multimeter to check for proper voltage output and resistance.
- Replace any faulty sensors or damaged wiring components as needed.
- Clear the DTC and perform a test drive to ensure the issue has been resolved.
Cost to Fix P2137
The typical repair costs for addressing a P2137 code can vary depending on the specific cause of the issue and the labor rates in your area. In general, replacing a throttle position sensor or pedal position sensor can range from $100 to $300 each, not including labor costs. The total repair bill, including parts and labor, could range from $200 to $600 or more. Keep in mind that diagnostic time and labor rates at auto repair shops can vary, so it's advisable to get a detailed estimate from a trusted mechanic before proceeding with the repairs.
