If there is difference between actual ECT and model ECT during driving, ECM/PCM sets this code(P0116).
Item | Detecting Condition | Possible Cause | |
DTC Strategy | Case 1 |
•
Rationality low side check | 1. Poor connection 2. IATS |
Case 2 |
•
Rationality high side check | ||
Case 3 |
•
ECT stuck check | ||
Case 4 |
•
Plausibility check / Monitor at cold condition | ||
Enable Conditions | Case 1 |
•
