Solenoid Valve

Checking the solenoid valve

Tools: Jump leads for connecting the solenoid valve to the car battery.




1. Remove the electrical connector on the solenoid valve.




2. Disconnect the hose running between the turbo compressor inlet and the "R" connection on the solenoid valve.

3. Connect the jump leads between the battery (12 V) and the electrical terminals of the solenoid valve.




4. The solenoid valve should be open when the current is on and closed when the current is off. This can be checked by blowing down the disconnected hose.

If the solenoid valve does not function as described above, it should be replaced.
