i just got a ls motor, the head says 95 but the dist is obd2 and the injectors look obd2 and the back of the intake mani says p75. there is a sensor a couple inches after the tb on the manifold itself. there is a plug with yel/blk and red/yel wires coming off of it, so only 2 wires. and there is a hose coming off of it. the only numbers on it were 136200-1350 and under that it said pcs7.

anybody help me with what sensor this is ?

 

here is a pic of a ls intake mani with the sensor circled in red.

thats the MAP sensor

 

isnt the map sensor usually 3 wires ? this only has 2 wires coming out of it. if it is the map sensor, what 2 of the 3 wires on my stock car should i wire it into to make it work because i own a ef civic and im putting this motor in there. or because its only 2 wires, i need to use my stock map sensor ?

 

wow shows how much you guys know.. the map sensor is on top of the throttle body. the sensor circle is your EVAP purge sylinoid. if you are staying obd1 then just leave the sensor there and dont worry about plugging it up or hooking the 2 hoses up seeing is that only obd2 ecu's read that sensor.

 

here, now no more confusion, and the MAP sensor is on the TB!



Info on the EVAP Solenoid!

Evaporative Emission (EVAP) Purge Control Solenoid Valve
When the engine coolant temperature is above 154 °F (68 °C) and the air conditioner on, the ECM/PCM controls the EVAP purge control solenoid valve which controls vacuum to the EVAP purge control canister.
