I do not have a code reader to tell me which one or all of my rear back up sensors are working so I am testing the OHMs. Does anyone know what these should read? I have several used ones from the junkyard that are all over the place. I want to purchase OEM, however, these are about $85/ea.
Doesn't look like many resistance values are given. When I added the PAM system to my 01 using new and used parts, I found my PAM plug had corroded pins. Once I found and fixed those I was fine. A bad speaker will prevent the system from working too.
Shop manual procedure below form the 2001 book. Wire colors will be different than your year and possibly pin positions. But the test procedures should be the same.....

Thank you in advance
Seems like a lot of work. Maybe try and see if Autozone or Ford dealer would just read the codes for you? I have a code reader and found one bad backup sensor. Center left.
