2010 GMC Sierra 1500 ProblemsReduced Power and Check Engine Light
The GMC Sierra 1500 uses a throttle position sensor (TPS) which commonly fails and causes:
- Check engine light illumination
- Reduced Power message
- OBD trouble code P2135
This issue is related to the throttle position sensor, and can be caused by faulty wiring to the TPS, bad connection at the TPS, or a failed TPS.
To correct this issue, the wiring harness, connector, and throttle position sensor must be inspected, tested, and/or replaced. The most common cause is a faulty TPS.
One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.
The inside door handles are prone to breaking.
