sorry bout spelling thanks!!!!!

 

Don't replace it unless you suspect it is truly not working correctly. Test your old one first with a multimeter.

 

Yes, but what are the testing proceedures?

 

i've never replaced a map sensor. they're also expensive...

 

Check for an even voltage sweep from around 1.5~2.0V at idle to ~4.5V at WOT on a fully warmed up engine.

 

Seldom here about map problems. Should go with a 2bar map if you run boost. I got a 3bar just incase I decide to do something stupid
