How to Resolve P0317 Fault Code?
1 Answers
You should visit a 4S dealership to have professional technicians clear the fault code. When clearing the code, it is crucial to strictly follow the prescribed fault code clearing method for the specific vehicle model. Under no circumstances should you simply disconnect the battery negative ground cable to clear the fault code. Additional relevant information is as follows: 1. The electronic control module detects cylinder misfires by monitoring changes in crankshaft rotation speed. However, wheel speed variations caused by rough road conditions may also lead to changes in crankshaft speed, thereby affecting misfire detection. 2. The Anti-lock Braking System (ABS) and Traction Control System (TCS) can determine whether the vehicle is driving on rough roads through wheel speed sensor signals. If the system detects severe road conditions that significantly impact misfire detection, it will instruct the electronic control module to disable misfire detection to prevent recording erroneous fault information.
