TEMPERATURE AND RESISTANCE SPECIFICATION

Temp. (°C/°F)	Resistance (kΩ)	Temp. (°C/°F)	Resistance (kΩ)
-40(-40)	48.14	40(104)	1.15
-20(-4)	14.13-16.83	60(140)	0.59
0(32)	5.79	80(176)	0.32
20(68)	2.31-2.59

Are the measured resistance within specification?
YES
- Clear DTC and Test-drive under enable conditions above-mentioned. After the test, If this DTC is set, recheck it thoroughly. If not, it is intermittent fault, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Substitute with a known-good ECTS and check for proper operation. If the problem is corrected, Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
