Code P2135 2016 GMC Sierra Description
The P2135 code for a 2016 GMC Sierra indicates a problem with the throttle position sensors 1-2 not being plausible. This means that the signals from the two throttle position sensors are not matching up or are not within the expected range, causing a discrepancy in the data being sent to the engine control module (ECM). The throttle position sensors are crucial components that monitor the position of the throttle pedal and communicate this information to the ECM, which then adjusts the air-fuel mixture for optimal engine performance. When these sensors are not providing accurate data, it can lead to issues with engine performance, fuel efficiency, and overall drivability.
Common Causes of P2135 2016 GMC Sierra
- Faulty throttle position sensor
- Wiring or connector issues
- Throttle body problems
- ECM malfunction
- Corrosion or damage to sensor components
