Oil Pump Solenoid Valve Failure Phenomenon

Views: 55     Author: Site Editor     Publish Time: 2024-05-08      Origin: Site

The main symptoms of oil pump solenoid valve failure include the following points:

Oil leakage: Oil pump solenoid valve leaks oil due to aging or damage to the seal.

Blockage: The oil pump solenoid valve is blocked internally, such as the valve core is stuck and the inlet and outlet channels are blocked.

Circuit failure: The solenoid coil is open circuited, has poor contact, etc., causing the oil pump solenoid valve to not work properly.

Overload: Excessive external load causes the solenoid coil to overheat or even burn out.

Mechanical wear: After long-term use, the mechanical parts of the oil pump solenoid valve will wear out, affecting its working performance.

Falling off: The screws are loose or falling off, causing the oil pump solenoid valve to malfunction.

In addition, if the solenoid valve of the oil pump is damaged, it will affect the power output of the car when refueling and the normal operation of the engine, manifesting as symptoms such as weak acceleration, failure to refuel, idling jitter, and abnormal engine noise. Coil short circuit, burnout, abnormal sound, external leakage, internal leakage, slow movement, no small valve function, small flow rate or no oil output from the large valve, etc. are all possible phenomena of damage to the oil pump solenoid valve.
