Is there any way to test a suspension solenoid on a rear wheel of a 07 expedition 2wd

 

Yes, there is !
There are at least 3 electrical checks you can do if you use a volt/ohmmeter .
The first would be to check if the ground connection is good.


The second would be to check if power (usually 12 volts) is getting to it when it is supposed to operate.


The third would be to check for continuity (specific ohmmeter reading) across it's terminals.


Then there are mechanical checks to check


If the solenoid is supposed to allow air pressure to pass when activated, you might hear it operate, but not open the passage to allow that air to pass. Confirmation needed.


And the reverse also needs to be confirmed, is it supposed to allow air to pass, then when activated prevent air from going through.


A lot depends on the application and what it is suppose to do.


This may not answer your question specifically, but if you know what is supposed to happen the above info should provide some type of guide.

 

Thanks hanky. I appreciate all the info.
