Component Inspection
- Check ECTS resistance
- IG "OFF" and disconnect ECTS connector.
- Measure resistance between signal and ground terminals of ECTS connector as the temperature rises.
- Specification :
RESISTANCE SPECIFICATIONTemp. (°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
- Substitute with a known - good PCM and check for proper operation.
If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Substitute with a known - good ECTS and check for proper operation.
If the problem is corrected, replace ECTS and go to VERIFICATION OF VEHICLE REPAIR procedure.
