Cruze throttle circuit fault.

Check whether the accelerator pedal and accelerator circuit are normal. If it is normal, it is recommended to replace it.

The throttle position sensor is mainly used to detect the change of throttle opening, and convert the change of throttle opening into an electrical signal and input it to the electronic control unit ECU. The ECU judges the working condition of the engine according to the throttle position signal, and then the computer corrects the fuel injection quantity and ignition timing according to these working condition information.

The failure of the throttle sensor will affect the idle speed control function of the engine computer, resulting in abnormal idle running of the engine (such as excessive or low idle speed, unstable idle speed and easy flameout) or abnormal acceleration of the engine (such as engine jitter during acceleration and slow acceleration response), and may also lead to intermittent jitter of the engine during operation.
