Automotive solenoid valve common fault one: solenoid valve coil short circuit or open circuit

1. Detection method: first measure the on-off with a multimeter, and the resistance value approaches zero or infinity, which means that the coil is short-circuited or open.

2. Solution: Replace the solenoid valve coil.

Automotive solenoid valve common fault 2: Solenoid valve plug / socket problem

If the solenoid valve is of the type of plug/socket, there may be problems with the metal reed of the socket and the wiring on the plug.

The solution to the problem is to correct the wiring error, repair or replace the plug and socket.

Automobile solenoid valve common fault three: solenoid valve spool problem

When the medium pressure of the solenoid valve is normal, press the red button of the solenoid valve, the solenoid valve has no reaction, indicating that the spool must be bad.

The solution to the problem: check the media for problems, such as whether there is a lot of water in the compressed air, and whether the liquid medium has a lot of impurities. Then remove accumulated water or impurities from the solenoid valve and piping.
