How to solve the p2 138 fault code?

The fault code p2 138 of Pacific Auto Network indicates that there is something wrong with the throttle or throttle sensor of the car. The solution is to detect the cause of the car's fault first, then go to the repair shop or 4s shop to repair the fault, and finally clear the fault code.

1, throttle failure

When the throttle valve 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 valve is damaged, it should be replaced in time. 2. There is something wrong with the throttle sensor.

When the accelerator pedal fails, the vehicle will show some problems, such as weak acceleration, serious collision and poor fuel supply. In this case, it is necessary to check the throttle sensor and pay attention to increasing the fuel quality every day.

After the car 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.
