You are a magnificent yet spiteful bitch......

My Cougar decided to scare me half to death last night. After chasing a false low oil pressure reading over the summer I found the issue and all was well. I recently did an oil change and had been driving her without any problems.

Fast forward to last night. I started the car and let her run for a few minutes as she’d been sitting for two week. Juuuuuuust before shutting down the low pressure chime came on and the gauge shot to ZERO. I cursed, too the Focus to work and came home. Out came the mechanical gauge. Hot idle 750 RPM reads a solid 18 PSI and @ 2000 RPM it reads 42. I putter on down to Advance Auto Parts and pick up a new sending unit. Chime is still going bananas.

Let me preface this by telling you perhaps the biggest quirk of this car.

If I turn on the rear window defroster, I can watch the oil pressure gauge show a higher pressure and also watch the pressure gauge decrease upon shutting the defroster off.

Full digital dash. No bimetal gauges.

Only thing I can think of at this point is the wiring has gone to shit and is giving too much resistance to the gauge.

I have to figure out a way to circumvent the chime whilst I dig into the EVTM to research so I can drive the damn thing. I have a feeling this is gonna take a bit of research.

I’ve owned this car for over 18 years. The first two years were bliss. She’s fought me ever since....

I think you’re on the right track there’s gotta be something insane with the wiring. That’s crazy.

one thing’s for sure though. even if it’s broken, it looks really good when it's broken!
