Engine/Transmission (1998.5 - 2002) Ohm specs for MAP sensor.

[tmacc]

I was expecting a sensor that looks like a IAT sensor. Thought part of it had broken off. Anywho, here are the readings I got.

Pin AB 10. 89k ohms

Pin AC 1. 727k ohms

Pin BC 11. 22k ohms

Taken at 72. 5 F degress

Is this a good sensor or not? I don't have access to a scan tool. I saw a post when I did a search, but darn if I can find it again on the 15 pages that came up. TIA

10 -- 1. 75

15 -- 2. 05

18 -- 2. 27

20. 5 -- 2. 44



Hope This Helps

Scott thanks for the reply, but how do I check the voltage w/ the truck running. Doesn't take a scanning tool?

 

[Graphic man]

YOU WOULD HAVE TO HOOK UP A VOLT METER AND RUN IT IN TO THE CAB AND DRIVE WITH THE BOOST GAGE AND CHECK IT THAT WAY,

THERE MAY BE AN EASER WAY TO CHECK IT BUTS THATS THE ONLY I KNOW



HOPE IT HELPS

I use a regulated air source. Works like a charm!

thanks graphic man helluva good tool

 

[Graphic man]

I also have IAT specs if anyone need them

 

[tmacc]

G-man, are they ohm specs?

 

[Graphic man]

as far as i know it is voltage

Please post the IAT sensor specs.
