reattasnohio reattasnohio Member Registered: 02/16/08 Posts: 16	Tonight as I was looking under my 91, I noticed a 2 wire plug close to the starter and out of the same bundle as the starter wires but this is unplugged. I cannot find where or if it is needed. Anyone have an idea? Chris in Ohio

The oil pressure sensor is the one that the ECM uses to turn the pump on _________________________ My name is Philip. '89 coupe '90 white coupe (brother's, being reconstructed)

I am going out in a minute to look and make sure it is the oil level sensor conection and not some thing else. _________________________

Richard S Richard S Member Registered: 02/10/01 Posts: 775 Loc: San Diego, CA	On my 90, it is plugged into the low oil sensor on the pan wall itself. As I recall, the oil pressure sensor is on the oil filter housing. _________________________ Richard 90 Red/Tan Coupe 90 White/Tan Coupe 90 Black/Grey Convert

reattasnohio reattasnohio Member Registered: 02/16/08 Posts: 16	Daniel, Thank you for taking the time to post those pictures. It is exactly the same plug you show in the pictures. I will check under it tomorrow and see if I can find where it properly goes. I am afraid my oil pan does not look the same as yours!!Thank you again Chris in Ohio

Greg Ross Greg Ross Member Registered: 06/19/00 Posts: 1799 Loc: Prince Edward Island, Canada	Chris, Your '91 engine has the oil level sender plug on the back of the engine and the oil pan is in fact somewhat different from the '88-'90 engines. You also want to be looking at the opposite/ back side of the pan. _________________________ "Betsy Blue" One Owner? Over 1/2 way to 1/2 a million miles The only known 5-spd S/C Reatta on the Road.

reattasnohio reattasnohio Member Registered: 02/16/08 Posts: 16	Greg, I remember when I bought my 91 the owner said it had a new engine because the company that did the oil change somehow started it with no oil and had to put a new motor in it. The motor does not seem to have a place in the oil pan to plug in. I have always noticed when I start it up the oil level low lights up. If I turn it off and restart it stays off. I now know why I guess. Also I can probobly jump them together and it will stay off all the time. MAYBE???? Chris in Ohio Thank you for all the help guys!!!!!!!

D-a-n-i-e-l D-a-n-i-e-l Member Registered: 12/02/06 Posts: 378 Loc: Fort Lewis WA/Iraq	I am not sure if it is an open circuit when full or if it is a closed circuit. If you are not getting a low oil warning right now it must be a normally open. If you are getting a low oil warning jumper them. _________________________

Richard S Richard S Member Registered: 02/10/01 Posts: 775 Loc: San Diego, CA	Greg, were you saying that the oil level sender plugs into the engine not the pan? How can that work? BTW, I dropped the pan on my 90 to remove the cam bearing that it spit out. Not a big job. If you have a 91 and want it stock, I'm sure Jim or Manik can provide a pan with the proper oil level fitting, assuming it is in the pan in 91. _________________________ Richard 90 Red/Tan Coupe 90 White/Tan Coupe 90 Black/Grey Convert
