■ Check ECTS resistance
IG "OFF" and disconnect ECTS connector.
Measure resistance between signal and ground terminals of ECTS connector as the temperature rises.
Specificaton :
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
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.
