DTC P111C-62: Control Module Internal Temperature Sensor/Intake Air Temperature Sensor Signal Compare Failure [11/2021 - 03/2022]: Procedure
WARNING: This page is about a different car, the 2025 Lexus NX 350h, 2024 Lexus NX 350h, 2023 Lexus NX 350h, and 2022 Lexus NX 350h. However, it is still accessible from the selected car via links, so may be relevant.
- 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 DTC P111C-62 is output A DTC P111C-62 and other DTCs are output B HINT:
If any DTCs other than P111C-62 are output, troubleshoot those DTCs first.
Result:
B
GO TO DTC CHART. Refer to DIAGNOSTIC TROUBLE CODE CHART [11/2021 - 03/2022]
Result:
A
See step 2
- Read the DTCs and record the Freeze Frame Data.
- CHECK FREEZE FRAME DATA (INTAKE AIR TEMPERATURE AND AMBIENT TEMPERATURE)
- 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.
- Perform "Inspection After Repair" after replacing the mass air flow meter sub-assembly.
Refer to INITIALIZATION [11/2021 - ]
Result
Proceed to OK NG
Result:
OK
REPLACE ECM. Refer to REMOVAL [11/2021 - ]
Result:
NG
REPLACE MASS AIR FLOW METER SUB-ASSEMBLY. Refer to REMOVAL [11/2021 - ]
- Using the GTS, read the values displayed in the freeze frame data recorded in step 1.
