I ordered this product because the low oil pressure warning light came on almost immediately when I started our 2005 Buick Lesabre. I've encountered this problem on several GM vehicles in our parking lot, and it's always just a bad sensor. These sensors are easy to swap out with simple hand tools and only take about 15 minutes. Just make sure you order the correct transmitter for your vehicle based on your sensor configuration and how it connects to your old part.
