What should I do if the Jinbei fault code appears repeatedly?

Regarding your inquiry, the fault code 0505 is: the idle system is working abnormally, and 0 120 is: the throttle position sensor circuit is faulty. In the process of cleaning the throttle valve, if there is wrong operation, the idle valve may be damaged. If there is a fault of poor contact, the code p0505 will be stored. I suggest you go to a regular 4s shop and check with a special diagnostic computer. If the related parts fail, they need to be replaced in time, not just to eliminate the fault code!
