Where is the oil pressure sending unit located and do I need special tools to change?

Engine oil pressure sensor is pictured below..top rear of engine. No special tools needed for replacement.

Thanks for using 2CarPros.com!

Hello,

The engine oil pressure sensor is located on the rear center of the engine block, near the top (see diagram below).
It can be replaced easily with simple hand tools.
First remove the wiring connector then unscrew the thread from the engine.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
