Autel Ultra Lite Fixed Mercedes P310253 Throttle Valve Fault

There ‘s a fault code “P310253: Throttle valve fault – The adaptation or adjustment is incorrect.” on this Mercedes-Benz LD. The throttle itself will play up and down, it won’t be stable in one position. Obviously if the engine runs, you won’t like it. So next I’m gonna use the Autel MaxiCOM Ultra Lite Scanner to fix the issue.


To solve the problem, you’d better replace the throttle body. Once you’ve done, it should be fine. If it does need coding, then Autel Ultra can help you.
