2011 Chevy Cruze P2135 Code: Does Throttle Body Replacement Require ECM Reprogramming?
My 2011 Chevrolet Cruze has been entering 'reduced power mode' and displaying the 'Service Stabil Trak' message multiple times this week. After turning off the ignition and restarting, the vehicle returns to normal temporarily but consistently shows the P213
First, the circuit should be tested — a diagnostic code does not automatically indicate a part replacement. There are two potentiometers in the throttle position sensor (TPS) system. The issue could stem from the electronic throttle body, faulty connectors, or wiring between components. While a malfunctioning PCM is possible, it's rare. Without proper circuit testing, the root cause remains uncertain. Replacing the throttle body may seem like a solution, but if the code returns afterward, you're back to square one. ECM reprogramming is generally not required for 2011 and newer Cruze models.
