DTC P111C-62: Control Module Internal Temperature Sensor/Intake Air Temperature Sensor Signal Compare Failure [08/2023 - ]: Procedure
- CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P111C-62)
- Read the DTCs and record the Freeze Frame Data.
Powertrain > Engine > Trouble Codes
Result
Result Proceed to P111C-62 and other DTCs are output A P111C-62 is output B HINT:
If any DTCs other than P111C-62 are output, troubleshoot those DTCs first.
Result:
A
GO TO DTC CHART. Refer to DIAGNOSTIC TROUBLE CODE CHART [08/2023 - 10/2024] , or Refer to DIAGNOSTIC TROUBLE CODE CHART [10/2024 - ]
Result:
B
See step 2
- Read the DTCs and record the Freeze Frame Data.
- CHECK FREEZE FRAME DATA (INTAKE AIR TEMPERATURE AND AMBIENT TEMPERATURE)
Pre-procedure1
- Using the GTS, read the values displayed in the freeze frame data recorded in step 1.
Powertrain > Engine > DTC(P111C-62) > Freeze Frame Data
Tester Display Intake Air Temperature Ambient Temperature
- Read the value displayed on the GTS.
Standard
Difference between the Intake Air Temperature and the Coolant Temperature is within 15°C (27°F).
HINT:
When the engine is cold, the value of the intake air temperature, ECM internal temperature and ambient temperature should be approximately the same.
Result
Proceed to OK NG
Post-procedure1
- None.
Result:
OK
REPLACE ECM. Refer to REMOVAL [08/2023 - ]
Result:
NG
REPLACE MASS AIR FLOW METER SUB-ASSEMBLY. Refer to REMOVAL [10/2022 - ]
- Using the GTS, read the values displayed in the freeze frame data recorded in step 1.
