What is the cause of Mercedes-Benz P001700 fault?
2 Answers
P001700 fault refers to the camshaft sprocket fault, which is most likely caused by dirty engine oil. It is recommended that the owner go to the 4S shop to replace the engine oil first, and then check the solenoid valve with a computer. Common faults of the car body include: Paint film peeling: It is caused by the ultraviolet effect, drastic changes in ambient temperature and humidity, contamination, aging and mechanical damage, which deteriorate or peel off the paint film of the car body. Wiper failure: It manifests as the wiper not working or working weakly, incorrect swing range and swing angle, unclear speed change or uncontrollable speed, etc. It is related to the failure or malfunction of the wiper motor, speed change switch, and mechanical parts such as the wiper swing rod.
When servicing Mercedes-Benz vehicles, I've encountered numerous P0017 trouble codes, which indicate a misalignment between the crankshaft position sensor and camshaft position sensor signals, typically occurring in Bank 1. This could be caused by a loose or broken timing chain – when the chain wears out, it affects the engine's internal timing synchronization. Alternatively, there might be an issue with the Variable Valve Timing (VVT) system. If oil pressure is insufficient or the VVT valve gets stuck, it can't properly regulate valve opening/closing timing, leading to mismatch. Sensor failures are also common, especially the crankshaft position sensor which is located lower and prone to water/dirt ingress. For repair recommendations: First read the trouble codes to identify the specific cause – don't attempt DIY fixes as specialized tools are required for disassembly, otherwise you risk causing more severe engine damage. We recommend diagnosis and handling at a Mercedes-Benz specialized repair shop to prevent minor issues from turning into major repair expenses. Regular chain inspections and oil changes can prevent such problems, saving both money and hassle.
