Here's what I measured on my '04.

I didn't find the actual oil pressure reading in the Tech 2 values; I thought it would say but I guess not. Here is what it read for sender voltages at various oil pressures as indicated by the dash gauge:

YMMV

Wonder if one could disconnect the oil pressure sending unit and send a small dc voltage to the gauge through the wiring harness connector? I'm not sure which pins would be the right ones to do that without looking at a wiring diagram.
Pretty sure it goes to the BCM and not to the gauge. It’s not 1970 anymore! You might not want to do that. :lol2:

Its
Did the shims make a difference?
It seemed like it went on fine. The new sensor didn't have any shims or anything with it. I test drove it today and the abs light went off, and I felt it try to engage while I was pulling up to the stop light.
I just ordered a scan tool, it's supposed to be here tomorrow night.

Thats likely because of the radio. Might not have the RSWC interface, or have been wired for it.
Looks like the module the PO has for the head unit does not integrate the audio controls. For the DIC buttons DIC personalization is set to off. I assume that’s why those buttons don’t work. I may need to pull the trigger on a clone Tech 2 at this point.

Started removing the side moldings, I had attempted to clean them with acetone but the color way still way off.
