What are the reasons for the failure of the fuel pressure sensor function in the Volkswagen Magotan?
2 Answers
Volkswagen Magotan fuel pressure sensor function failure reasons are as follows: Alarm line poor contact: For the Volkswagen fuel pressure sensor function failure, first check whether the alarm line connection is poorly contacted or has interference. Sensor failure: Check the high and low fuel pressure at idle. Possible causes include intake pipe throttle position sensor and its circuit failure, vacuum line leakage, or engine control unit damage. It is recommended to visit a professional repair shop for diagnosis and repair. Fuel pressure sensor malfunction: If the low-pressure fuel pressure sensor fails, the fuel pressure pre-adjustment will replace the fuel pressure regulation. The fuel pressure will be approximately 6.5 bar. If the low oil pressure is insufficient for a long time, it may cause abnormal wear of the fuel pressure regulating valve, leading to sticking and ultimately resulting in the failure of the fuel pressure sensor function.
The malfunction of the fuel pressure sensor in the Volkswagen Magotan may be related to several factors. This sensor is responsible for monitoring the pressure in the fuel system. Once it fails, the car may experience difficulties starting, shaking, or even the malfunction indicator light turning on. Based on cases I've handled in the past, aging of the sensor itself is the most common cause. After prolonged use, the internal components of the Magotan's sensor can wear out, especially in high-temperature environments where they are prone to burning out, or oil contamination can block the probe, leading to signal distortion. Another issue is improper installation during major repairs, such as excessive torque damaging the housing. I recommend regular inspections of this component after five years of use, rather than waiting for problems to arise, as repair costs could be higher otherwise. Additionally, if the sensor itself fails, replacing it with a new one usually resolves the issue. Avoid opting for cheaper aftermarket parts; ensure quality instead.
