Suzuki excelle didn't respond to the throttle.

1. Throttle motor failure: Suzuki Excelle's throttle is controlled by the motor. If the motor is damaged or has problems, the throttle may not open or close. Check whether the electrical connection of the motor is normal, whether the voltage and current are normal, and whether the motor can work normally.

2. Fault of throttle position sensor: Suzuki Excelle ECU needs to detect the position and state of throttle through throttle position sensor. If the sensor fails or fails, the ECU may not be able to control the opening and closing of the throttle. It is necessary to check whether the electrical connection, voltage and current of the sensor are normal and whether the sensor can work normally.

3. Throttle control circuit failure: The ECU of Suzuki Excelle needs to control the opening and closing of the throttle through the circuit. If there is something wrong with the wiring, the ECU may not control the throttle normally. Check whether the electrical connection of the line is normal, whether the voltage and current are normal, and whether the line is damaged or disconnected.
