How to deal with p2 138 fault code?

If the fault code of the vehicle is p2 138, there is something wrong with the throttle or throttle sensor of the vehicle. The specific reason is to go to a repair shop or a 4s shop for professional inspection. Details are as follows: 1. Throttle failure: when the throttle fails, the vehicle will have symptoms such as engine jitter, unstable idle speed, weak refueling, and difficulty in starting a cold car. In this case, it is necessary to clean the throttle again, especially to remove the sludge attached to the throttle. If the throttle structure is damaged, it should be replaced in time. 2. There is something wrong with the accelerator sensor: when the accelerator pedal fails, the vehicle will have problems such as weak acceleration, serious frustration and poor fuel supply. In this case, the throttle sensor should be checked and daily attention should be paid to increasing fuel quality as much as possible. After the vehicle is repaired, the fault code must be cleared in time, otherwise the memory of the vehicle electronic system will be disordered and some unnecessary troubles will be brought to the later stage.
