Code P2135 2017 Chevrolet Silverado Description
The P2135 diagnostic trouble code (DTC) for a 2017 Chevrolet Silverado indicates a problem with the throttle position sensors 1-2 not being plausible. This means that the signals from the throttle position sensors (TPS) are not matching up as expected, leading to a discrepancy in the data being sent to the engine control module (ECM). The TPS is a crucial component that monitors the position of the throttle valve and sends this information to the ECM, which uses it to determine the appropriate air-fuel mixture for combustion. When the TPS signals are not in agreement, it can lead to issues with engine performance, fuel efficiency, and overall drivability.
Common Causes of P2135 2017 Chevrolet Silverado
- Faulty throttle position sensors
- Wiring or connector issues in the TPS circuit
- Corrosion or contamination in the TPS connectors
- ECM software or hardware malfunction
- Mechanical issues with the throttle body assembly
Symptoms of P2135 2017 Chevrolet Silverado
- Rough idling or stalling
- Hesitation or lack of response during acceleration
- Reduced fuel efficiency
- Check Engine Light illuminated
- Limited or erratic throttle response
How to Fix P2135 2017 Chevrolet Silverado
- Begin by performing a thorough inspection of the TPS wiring and connectors for any signs of damage, corrosion, or loose connections.
- Test the TPS using a multimeter to check for proper voltage output and resistance values.
- If the TPS is found to be faulty, replace it with a new, OEM-quality sensor.
- Clear the DTC from the ECM memory using a diagnostic scanner and perform a throttle relearn procedure to recalibrate the TPS.
- Test drive the vehicle to ensure that the issue has been resolved and that the TPS signals are now functioning correctly.
