Hi I need the part number for the map sensor of the 91-93 engines.

Thanx

I don't know what it is but its the same for the 3.1 as well. I think GM used the same MAP sensor for a ton of cars for a long time. It only looks different because of the carrier it sticks into.

I found that there are dif 1 bar map sensors. Im using one from an v8 and apparently thats why Im running rich above 50% TPS. The first weeks I didnt have problems and was using my bros 1 bar map sensor from his Fiero.

Thats why I ask for the part number.

Is there any source I can get the part number?

Thanx

gmpartsdirect.com probably, or call the dealership and have them compare the MAP sensor numbers. Unless the V8 sensor was using a different voltage reference, i dunno why it would be causing problems. It should have thrown a code if that was the case.

Here is the info I foun on the web:


For a 1 bar GM sensor
16072049
16017460
16187556

Vout = Vref ( ( 0.01059 * P ) - 0.10941 )

V in voltage, and P in kPa

EG:
Vref = 5.00 Volt
P = 80 kPa
Vout = 3.69 V

A BARO sensor,
16022790
16006833
1 bar map sensor
16006835
16042459

Vout = Vref ( ( 0.01059 * P ) - 0.1518 )



A 2 bar GM sensor
(can't find numbers)

Vout = Vref ( ( 0.005 * P ) - 0.04 )



A 3 bar GM sensor
16040749
16036394

Vout = Vref ( ( 0.003183 * P ) - 0.003529 )
