4 wire map sensor?
4 wire map sensor? So I ordered the wrong Bosch 3 bar map sensor and it's a 4 wire instead of 3 wire. From what I've found the extra wire is actually the iat probe, so this sensor is an iat and map sensor in one. Does anyone have any info on wiring this sensor up. The sensor is commonly used in Saturn sky/ Pontiac solstice. Sensor # 0281002845
are you in the houston fbody page in facebook? i think i saw this question in there.
pin 1- ground
pin 2- iat signal (goes to ur iat signal wire, usually tan or black)
pin 3- 5v reference
pin 4- map sensor signal

No but I am in Houston. I said screw it and just ordered the correct sensor just to keep simple and one less possible problem on first start up.
Thanks for the info though I'll keep the sensor for back up.
