Did the computer detect that the throttle is out of order?

If the fault light is on, it may be damaged. Generally, the idle motor and throttle position sensor will not be broken. There is probably something wrong with the circuit from the computer to the sensor. The fault light is sometimes on and sometimes off, so it is not a sensor problem. Poor circuit contact in rainy days. Changan models often have this problem. Check carefully to find the root cause.
