I have searched and can't find anything on this, and i may be crazy, or my car is missing some ****, but i can't find a MAP sensor on my car... I've had the motor apart to put heads on and everything, and i have yet to see one... I know they are on the firewall on 93 back, right behind the intake, but i can't find one on my 94... I don't see a plug for one either... Also, I looked at another car recently and i couldn't find one on that car either... Anyone know if they even have one, and if they do, where the hell it is... At work my 94 calls for the same as the 93 back cars do, but i sure as hell can't find the thing... Anyone have any idea or know???

Sure....don't waste your time looking for it........SN95 systems don't use a MAP/BP sensor.

Okay, well then what determines the load on the engine when pulling hills and what not?

The MAP is not used to determine load in '89+ systems, they are Mass Air systems.....the MAP switched to a BP or Barometric Pressure sensor then, and load was based in RPMS + MAF + TEMP + TPS + etc.....SN95 systems uses the MAF + internal logic to calculate barometric pressure + load based on MAF + TEMP + TPS + etc......
