1990 MAP sensor

[jrd1990zr1]

This may sound like a stupid question. Where is the MAP sensor on a 1990 ZR1 installed? My car is kicking out a code 33.

Thanks

its at the very back center of the olenum(intake) you will see ahorizontal alluminum piece unbolt it (torx bolts) 2of them. disconnect the connector take the vaccume hose off .its not hard .easier with1/4 in drive ratchet and torx bit/ hope this helps

rear center, under the aluminum bracket, you can use
your roof ratchet to get the torq bolts off.
check the hose, make sure it's still rigid, if it's pliable
it's toast, replace that bad boy.......party on

Roof ratchet . really very cool but my hose is still stiff
