I have a bad oil pressure sensor or the dealer also refered to it as a thermal sensor???? I would rather do it myself if it is easy enough. Has anyone ever done this? Where the heck is it located?

 

What are your symptoms. Theres two sensors. One for oil level and one for oil pressure. The oil level sensor is in the bottom of the oil pan. The oil pressure sensor is near the oil filter housing. Both are fairly easy to replace.

 

Where can a replacement oil pressure sensor be purchased? I would like to avoid paying dealership prices.

 

Try force five - Concord NH

Be careful because you've mentioned Oil Pressure, and Oil temperature then dank added oil level. Make sure you get the right one.
