Okay my situation is I just finish with my head resurface and haed gasket replacement a couple weeks ago so then today i boosted. I boost at around 7 to 8lbs with a 96 gsr teg.. everytime i boost i get a cel three which is map sensor... but when i drive normal no code 3..

so my question is how to fix does that mean i have a bad map sensor?

 

no it means you drive a honda which doesn't have a boost map so you can't let your ecu see boost.

It's pretty obvious

what's your setup?

 

I just have a stock 96 teg with the greddy kit.. It never happened before.. Just started..
how would fix this problem..
Thanks in advance

 

would this product fix it or i mean bypass it

your blue box is either broken or incorrectly wired. check for function!

 

the blue box is blinking if thats what you mean
..

should be wired correct cause it didn't happen before..
maybe broken

 

its supposed to blink. check the wires connected to the MAP sensor
