Hi everyone!

I been searching for resistance values vs temperature for magnum coolant sensor and IAT.
I need it for the megasquirt in my Valiant.
Been searching, but not found good information..

factory drivability manual will tell you or someone that works at a shop that can print out the tests for either code.
 
Yeah, got like 4 hours to closest mopar workshop... :-/
And the manuals are very expensive and delivery time is looong from the states as is today...
 
From a '90 manual, IDK if they changed ...

Coolant Temp Sensor Response Chart (same as IAT values)
110 degs = 4.20 volts
120 = 4.00
130 = 3.77
140 = 3.60
150 = 3.40
160 = 3.20
170 = 3.02
180 = 2.80
190 = 2.60
200 = 2.40
210 = 2.20
220 = 2.00
230 = 1.80
240 = 1.62
250 = 1.45
Temperature to Resistance
32 degs = 30 - 35 K ohms
77 degs = 9 - 11 K ohms
212 degs = 640 - 720 ohms

here is info from my 93 fsm. 1 st pic is chart of values, 2nd and 3rd pic should be how to test cts. pics in the next block are of charge temp/iat, which appears to mirror cts. hope this helps. rick w.
