Question about 2006 Pontiac Grand Prix
Oil changed month ago only did twice and now nothing, oil is full
Oil sending unit for sure! it should be on driver side near botton of engine and will have a pig tail connector with 2 wires leading to dash board gauge. When you replace, purchace a oil switch socket and make sure oil is drained. Pull out old one, the new one should have some threading material on thread. DO NOT overtighten. Just a little beyond the white threading material. Hope our answers help! Good luck and ask again if you have further issues

I agree. The oil sending unit (sensor) could be giving a false reading. Replace the sensor, have the codes cleared. Also know, that disconnecting the battery multiple times will\can cause the computer to send out false defaults and thus check engine light etc will come on. I also suggest having the mechanic who did your oil change (if applicable) do a pressure test on your cylinders as you may also have bad "O" Rings. This will only cause your engine to burn oil, miss slightly, however, will progress over time if not corrected

Testimonial: "thank you so much will call them now"
Since it happened only twice, I would wait to see if it happens more often before replacing the oil pressure sending unit. The car will run fine even if it says low oil pressure that is due to a defective oil pressure sending unit. The only time there would be a problem is if the car really did have low oil pressure and you did nothing about it.

SOURCE: '92 GMC PU has low oil pressure
With that kind of maintenace pump and bearings should be ok,the oil pressure sending units get weak on these models I have replaced alot of these for this same condition.The check engine light reads its voltage from the sensor.
