Chevrolet Cheng Jing has no oil, no fire and no fault code.

The reason why Chevrolet Cheng Jing has no oil, no fire and no fault code is that the battery voltage is too low. The solution steps are as follows.

1. Test the battery voltage. If it is lower than 12V, it means that the energy supply is insufficient and needs to be replaced in time.

2. Check whether it is caused by carbon deposition, clean the throttle and test and replace the spark plug.

3. Test the ignition switch and test the starter.
