How to solve the P0317 fault code on Excelle?

[SanMila]

Here are the solutions for the P0317 fault code on Excelle: 1. Poor fuel quality or excessive engine carbon deposits leading to poor combustion conditions may trigger the fault light. Solution: Clean carbon deposits and replace engine oil. 2. Faulty oxygen sensor in the engine, which typically illuminates the engine fault light in yellow without affecting normal driving. Solution: Repair the oxygen sensor. 3. Clogged fuel injectors or intake valves with carbon buildup can trigger fault light warnings. Solution: Clean fuel injectors and intake valves. 4. If the issue is insufficient or deteriorated transmission fluid, worn/broken transmission bearings, bent transmission shafts, abnormal gear meshing, incorrect meshing clearance, or gear tooth surface peeling. Solution: When metallic dry friction sounds occur during driving and the transmission case feels hot to touch, this indicates insufficient lubrication or deteriorated oil. Refill or inspect fluid quality, replace if necessary.
