TEMPERATURE AND RESISTANCE SPECIFICATION

Temp.(°C)	Temp.(°F)	Resistance(kΩ)	Temp.(°C)	Temp.(°F)	Resistance(kΩ)
-10	14	8.5~9.7	20	68	2.3~2.5
0	32	5.4~6.1	30	86	1.6~1.7
10	50	3.5~3.9	80	176	Approx. 0.3

Is resistance within the specification?
YES
- Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure
NO
- Check IATS for contamination, deterioration, or damage. Substitute with a known-good IATS and check for proper operation. If the problem is corrected, replace IATS and then go to "VERIFICATION OF VEHICLE REPAIR " procedure
