Need help with Oil Sensor Switch Replacement
My 07 Overland threw a P0520 code at me a couple of days ago. I pulled the power to reset it, but the check engine light came back a little later that evening. This is my first Jeep in over 30 years, but I've read that the oil pumps are pretty solid, so I figure it is the oil sensor switch. My mechanic wants to charge me $160 to replace it, but I don't really want to spend that much money to put in a $25 part. I got the skid plate off and located the switch, but I'm stumped by the connector. I know the red tab has to be moved to the side, but I can't get it to budge. I've tried everything I can think of. I tried out other red tabs in the engine bay and I can get them to move no problem, just not the one on the switch. Something about coming from underneath or something else? I even tried a small screwdriver, but I can't get it to move. I'm hoping there is a trick, because I'm ready to admit defeat. Any ideas would be greatly appreciated.
