- The PCM does not illuminate the malfunction indicator lamp (MIL).
Important: The actions listed below are in order of highest to lowest priority.
- The PCM determines a default TFT using one of the following:
- If any ECT DTCs P0117 or P0118 are set, then the default TFT is equal to 135°C (275°F).
- If the ECT is 125°C (257°F) or more, then the default TFT is equal to 135°C (275°F).
- If the engine run time is less than 300 seconds and:
- No intake air temperature (IAT) DTCs P0112 or P0113 are set and IAT is available, then the default TFT is equal to IAT.
- Any IAT DTCs P0112 or P0113 are set or IAT is NOT available, then the default TFT is equal to 90°C (194°F).
- If the engine run time is greater than 300 seconds and no IAT DTCs P0112 or P0113 are set and IAT is available and ECT is between 40 and 125°C (104 and 257°F) and:
- IAT at startup is less than 15°C (59°F), then the default TFT is equal to the ECT plus 5°C (8°F).
- IAT at startup is greater than 35°C (95°F), then the default TFT is equal to the ECT plus 10°C (16°F).
- IAT at startup is between 15 and 35°C (59 and 95°F), then the default TFT is equal to the ECT.
- If the engine run time is greater than 300 seconds and any IAT DTCs P0112 or P0113 are set or IAT is NOT available, then the default TFT is equal to the ECT.
- If the engine run time is greater than 300 seconds and ECT is less than 40°C (104°F) or more, then the default TFT is equal to 60°C (140°F).
- The PCM freezes shift adapts from being updated.
- The PCM records the operating conditions when the Conditions for Setting the DTC are met. The PCM stores this information as Failure Records.
- The PCM stores DTC P0711 in PCM history.
