sensor beside map senor has no vacuum line attached

**blakgtp** · 07-27-2012

on my 97 gtp the sensor on the left of the map sensor has an elbow for a line but no line. the factory boost gauge on the dic reads zero boost even when i am in boost so i am guessing thats the reason. anyone know which line goes into this sensor and where it connects to?

iirc-- it should run to a tee fitting under the s/c snout and from there it goes to your fuel press regulator.

just reread your thread-- I thought you were talking about map sensor-- sensor beside it could be evap. Here's some help

If you're talking about the vacuum tree, the middle port goes to the HVAC inside of the car. I believe on 97's it should be capped off. The red line in the picture above ends up here (behind the center console, near the firewall, passenger side.)

it's a round-ish sensor on the left of the map.

also, i was looking in my engine bay for a while and i think the evap was removed, cant see the canister anywhere

evap can on a 97 is located in the r/t rear wheel well

well, whatever the elbow was supposed to go to, i blocked it off and took the car for a spin. boost gauge now works and the car drives much smoother, better throttle repsonse.
