How to Fix P0101 Trouble Code?
1 Answers
Automotive PO101 trouble code indicates a malfunction in the mass air flow sensor, which can lead to engine performance issues such as poor acceleration and black smoke from the exhaust pipe. More critically, it can cause excessive exhaust emissions. If the mass air flow sensor is not working properly or is faulty, you can perform a no-disassembly cleaning of the fuel injectors. During the cleaning process, carbon deposits in the combustion chamber and on the piston top can also be removed. It is recommended to clean every 20,000 kilometers to effectively prevent excessive carbon buildup. Below are the solutions: 1. After troubleshooting the vehicle, the trouble code must be cleared. When clearing the code, it is essential to strictly follow the specified method for the particular vehicle model. Do not arbitrarily remove the battery negative cable to clear the trouble code. 2. Otherwise, it may cause issues, such as the vehicle's control computer losing its memory. Most vehicle models' central computers have memory functions. If the battery negative cable is disconnected, the random access memory (RAM) storing engine operation data will be lost, affecting the vehicle's performance for an extended period after repairs. Alternatively, the cleared trouble code may reappear after driving for some time. 3. It may also result in the loss of normal functions, such as the audio system's lock feature, which is one of the most commonly encountered issues.
