My map sensor reads the same thing all the time. It reads 187Kpa all the time whether it is experiencing ambient or vacuum under cranking or pressure being applied. The voltage coming off the map 'wire' never changes and neither does the reading on the haltech software. I think its busted, anybody had this problem?

I've got a spare 3bar I would sell you.

let me know if you are interested

check the vacuum line, and check the wiring and then replace map sensor

I have checked everything, wiring, and vaccum.



How much for the spare 3 bar?
