Intake Air Temperature Sensor??

[zlobo]

does any one have temp vs ohm spec on the stock sensor?
i need spec at:
degres in celsius, i net to know the resistanse for each temp.

You need a freezer, a kettle, a thermometer, and a multimeter.

It looks like a nice linear line so far.

[zlobo]

seams so..

[S2central.net]

Nothing like a bit of reverse engineering

[zlobo]

can some one explain wat the word "MONOTONICALLY" means?
its about this MAT

[zlobo]

case closed if anyone is intrested i cam put together a full print out

I'm sure some of us would be interested.

For verification...

Here is a graph from the factory:

And this is my best guess at getting numeric data from the graph:

-35	400
-25	420
-10	440
5	460
15	480
27.5	500
40	520
52.5	540
65	560
75	580
87.5	600
100	620
112.5	640
125	660
140	680
150	700

It seems pretty close to your values.

Are you diagnosing your sensor, or do you have bigger plans? I plan on using this to monitor the IAT on a multifunction boost gauge that I am working on.

Anyway, this is my first post here. Greetings...

yes it's very close to my list
