![]() Our certified mobile mechanics can come to your home or office to perform the Check Engine Light. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. If the TSB has not been generated, you must follow the specific troubleshooting steps for this code to pinpoint the exact source of the fault that the PCM detects in order to put the engine into failsafe or fail-safe mode. P2101 is a diagnostic trouble code (DTC) for 'Throttle Actuator Control Motor Circuit Range/Performance'. If other codes are found, you should check the TSB associated with the specific vehicle and that code. Description: general motors 2005-2011 chevrolet cobalt, hhr 2006-2010 pontiac solstice, g5,g4,2007-2010 saturn. This is a tricky system to diagnose on a GM. It opens the throttle based on the two PPS sensor located on the gas pedal. Since this is a drive by wire setup the throttle body uses two TPS sensors to determine the throttle plate position. This code is informational and in most cases the function of this code is to alert the driver that the PCM has initiated a failover due to a fault or failure in a system that is not directly connected to the throttle control actuator. 5,332 Answers The throttle position sensor is the throttle body. WHAT IS ERROR CODE P2176 Inspect the throttle body for the following conditions: A throttle blade that is NOT in the rest position A throttle valve that is binding open or closed A throttle blade that is free to move open or closed WITHOUT spring pressure If a condition is found, replace the throttle body assembly. The second step for this code is to complete a PCM scan to determine other trouble codes. In some cases, this can save you a lot of time in the long run by pointing you in the right direction. What Does the P2176 Code Mean The Engine Control Module (ECM) determines the drivers intent based on input from the accelerator pedal position sensors, then calculates the appropriate throttle response based on the throttle position sensors. The first step in troubleshooting any problem is to review the vehicle-specific Technical Service Bulletins (TSBs) by year, model, and powerplant.
