What is this Sensor? - See Photo (Page 1/1)
Romsk JUL 20, 10:29 AM
I am making a Sensor Map as a small placard I can stick to the inside of the rear Trunk Lid. I have been able to identify all the sensors except for this one.

See attached photos.

Can anyone tell me what it is?

Thanks

12. Regardless the numbers on motor diagram too small/distorted to read.

theOgre,
Ignore the map I drew, when it was converted to a .jpg it lost resolution. I just included it to show the green square with a question mark (the approximate location of tye unknown sensor). When I print it out I can read it fine. I wanted to keep it as small as possible.

But look at the photo. That is the "sensor in question" circled in yellow. Do you know what it is?

Once know that, I will post my Quick Reference cards on my home page.
Thanks.

The piece you have circled is the EGR vacuum solenoid.

Thanks,
Most of what I drew was from a drawing on the Fiero Store. I had made some improvements but this makes sense now. I will be posting this on my web page later today.
Thanks again.

theogre,

While you are here... I am making a quick reference card for Fluids and Lubricants. After researching several sources, I was able to boil it down to the following (see attached):
Some sources referred to Corvettes and other cars that have Regular or Limited Slip Differentials and some others features the Fieros clearly do not have - so I did not include those.
As you may know, there is some misconception on what to use in Fiero manual transmissions, some sources (even GM in some cases) state 5W30 Oil, but I believe that
is wrong so I put down Synchromesh Transmission Fluid 5W30 (I think is does not have all the detergents that Engine Oils have).
I think I have it all worked out except for the "Transaxle" which again is shown in red as 5W30. Correct me in I am wrong, but the Fiero differential is an integral part of the manual transmission, so it uses the same lubricant as the transmission - Synchromesh Transmission Fluid 5W30.

Can you confirm this. What I colored red is what I think does not apply for Fieros.
Are there separate fills for the Transmission and Transaxle? My brother uses to handle all that for me so I am not sure.

Thanks.
