VOLTAGE RESISTANCE REFERENCE CHART

Ambient temperature (°C (°F))	Resistance between terminals 1 and 2 (k Ω)
-30 (-22)	507
-20 (-4)	284.5
-10 (14)	164.2
0 (32)	97.5
10 (50)	59.6
20 (68)	37.46
30 (86)	24.18
40 (104)	16
50 (122)	10.83

If the measured resistance is not specification, substitute with a known-good ambient temperature sensor and check for proper operation.
If the problem is corrected, replace the ambient temperature sensor.
