Buick Hideo's throttle is not responding. The computer reported that the throttle was out of order.

Throttle position sensor fault, electronic control module fault.

1. Fault of throttle position sensor: The throttle position sensor is responsible for monitoring the throttle opening and transmitting the signal to the control unit. Once the throttle position sensor fails, the throttle will be unresponsive and the throttle fault light will be on.

2. Failure of electronic control module: The electronic control module is responsible for processing all sensor signals and controlling the operation of the engine. Failure of ECU will lead to problems such as no response of throttle and lighting of throttle fault light.
