Map sensor Low voltage code

[vegasviper]

What causes that?

Bad MAP sensor, loose mounting, oil contamination...

I had the same thing on my MAP sensor. The Roe system doesn't have a solid mounting location and is only zip tied on. Make sure the zip ties are tight.

Its zip tied and i changed the MAP sensor. How would oil come into play?

If you have any blow by from the SC. Do you have a catch can?

Did you clear the code after you changed to a new sensor? Are the zip ties tight? Mine was loose and it threw a code.

I have blow by and a catch can. MAP ZIP TIED WELL

 

[GTSnake]

Was the code cleared and it keeps coming back? Are there any obstructions in the vacuum tube? Electrical connections tight? Other than that I'm starting to run out of ideas.

I could be something else on the 5v circuit. I was showing a bad intake air temp sensor (low voltage) so I changed it. I was still getting the code for a intake air temp sensor and a bad tps (low voltage) so I took it to a friends shop so we could plug it in and that's when it showed a bad map sensor. Granted this was on a OBDI (95) and the OBDII is a more precise trouble shooter but you may want to check anything on the 5v circuit.
