Specification:
ECTS RESISTANCE SPECIFICATIONTemperature Resistance(kΩ) 20°C(68°F) Approx. 2.31 ~ 2.59 40°C(104°F) Approx. 1.15 80°C(176°F) Approx. 0.32 - Is resistance within the specification?
YES:
- Check for poor connection between PCM 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 ECTS for contamination, deterioration, or damage. Substitute with a known-good ECTS and check for proper operation. If the problem is corrected, replace ECTS and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
