TCS solenoid

[Rick N.]

Who rebuilds/restores TCS solenoids ?

I have one that ohms out ok but doesn't energize.

Thanks, Rick.

Re: TCS solenoid

Rick, have you tried to spray some pentetranting oil in the vacuum ports to see if the piston frees up maybe some rust in the solenoid chamber that the piston slides up and down. its just a electro magnet that moves a metal piston up and down to open or close the passage. also be sure to check out that battery voltage is correct and you have a ground. these can be tested on or off the car. I have used a test light the energize the solenoid by touching the ground side with the pointed end, just make sure you have power with key on. or unplug wire connector and use a couple of jumper wires.

Re: TCS solenoid

I've taken it completely apart and cleaned it.
There was a sticky film of oil on the piston and inside the bore of the magnet.
The windings ohm fine however, it won't move the piston.
Thanks, Rick

Re: TCS solenoid

If you have an ohm meter measure the resistance of the coil.
Possible it is shorted or burnt out?
