Dongfeng Xiaokang K07 fault accelerator line voltage high fault code P0 123 What fault?

The rotating shaft of the resistor is linked with the throttle valve, which is caused by fully open contacts and empty contacts.

1. When the throttle valve is in the idle position, the idle contact is closed and the idle condition signal is output to the computer. When the throttle valve is in other positions, the idle contact is opened, and voltage signals with different angles relative to the throttle valve are output, and the computer identifies the engine load according to the signal voltage value.

2. The change rate of signal voltage in a certain period of time indicates whether it is an acceleration state or a deceleration state. According to these working conditions, the computer corrects the fuel injection quantity and controls the fuel cut.
