Cheap and simple solution to the problem
It seems to be working ok. Had intermittent error code of abnormal oil pressure. After changing this sensor it seems to be working ok.One tip for changing it out. I've seen a lot of videos which suggest to remove the oil filter, and even alternator. But on fact all you need is a very deep socket or you can buy special one from Lisle (13250 IIRC). With it you can just unplug the old sensor, put the socket on it (it's tight, but you will be able to fit the socket between the oil filter and alternator) with ratchet (or breaking bar - mine needed A LOT of torque to break it loose) and unscrew it. That's it. Super simple and you actually don't need to remove anything from the engine. Then just screw new sensor back with the same procedure reversed.One more note - you might run into alternator when unscrewing it. Still you don't have to remove the whole alternator out - you can just unscrew it's main positive line (be sure not to touch the ground with it - otherwise big kaboom :) or even better- disconnect the battery), and unscrew three small bolts holding the side cover of the alternator. With it removed this provides easy access to the oil sensor.

Will use again.
2nd purchase on this item. First install lasted a little over 18 months. It started leaking oil but still functioning. I am not ruling out that I damaged it while installing. It is a blind install and took me over 2 hours. Second time around it was much easier to install since I knew what to do. Only took me 30 minutes this time. With doing this twice I still haven't spent half of what the dealer quoted me to fix this. I will do it again if I have to and still be ahead!

Happy customer at this time!
Item was an exact replacement for a 2008 GMC Acadia SLT. No problems yet after a week of run time. Was able to use a shallow oil sensor 1-1/16 socket bought separately.
