Evois thanks for the reply "quick as a breeze" LOL going to take 4 hours and cost 600.00 for a 75.00 part over 500 just for labor. Hybrids are a bad idea.
Thanks all for your help tho made this a bit easier

 

$600 bucks for an oil pressure sender unit?

It is kind of hard to get at and exactly the same on a non hybrid. It's at the back of the engine on the driver's side. It is a screw in part. The huge intake manifold makes it hard to see and get at. But I would do it in my shop at home for less than $100 labor.

 

Wow Hillblly what state do you live in???? i have called all over and everyone is about the same

 

I guess if you have like a diving board-like lift or attachment, you can easily access it with an open or closed ring spanner

 

I'm in South East Michigan and that price is what I would charge as a side job to do it. It would probably take me a little over 2 hours.

Attached picture of the engine with the intake manifold off. Evois has the drawing as shown from the driver's side rear.

I'm betting a special 3/8 socket would just unscrew it. The problem is geting at it without removing the intake.

 

This guy has done it without removing the intake.
