Oil Pressure Sensor/Screen Replacement

[2006Tahoe2WD]

Cleaning out the connector on the oil pressure switch and reusing is good move. Also check the ground back there. It there's oil all over it you'll want to get that clean and squared away as well. At least that's my experience. The switch and the connector should not be failing.. it's the oil and that ground strap. Not a mechanic, just my two cents.

So far the new sensor is working but I'm still not sure it is reporting the correct pressure or the actual pressure is flakey because e.g. the famous O ring is leaking. At this point the pressure is around 40 or more so I'll continue to watch it. Good point about the ground strap. I'll check it next time I'm in the area - no salt or corrosion in my area.
