Ran codes on my 89" f-150 with 4.9 and got code 32-EVP below voltage. I took the EVP off and need to know how to test it. Can anyone help?

 

i just did this on tuesday. if you have a haynes manual it will be listed in there. there are more then a few things to test. voltage at the connector. resistance across two of the pins. I dont remember which they are but across two pins you should have around 5k ohms with the plunger out and about 100ohms with it all the way in. i believe these are the two pins across from each other. if you are holding the sensor as if the pins were a triange facing up, then jump the top pin and the right pin and you should get around 100ohm, should be no less according to the manual. There is really alot to it and i probably got part or all of that wrong but its the best i could remember. the haynes manual isnt very expensive and while they arent great, they can help sometimes.

Here's a quick test for the EVP and wiring, thanks to fefarms;
-Remove the EVP and leave the wire harness connected on it.
Run a KOEO test and you should get code 31 (maybe 32)
-Now push the EVP plunger all the way in and tape it down.
Again, run a KOEO test and you should get a code 34.

Is the Code 32 a KOEO or CM code?
