1. 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 [06/2024 - ] 

Result: 

B 

See step  2

Pre-procedure1

1. 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
   Coolant Temperature
   Intake Air Temperature
   Engine ECU Internal Temperature

   Procedure1

2. Read the value displayed on the GTS.

   Result

   Result	Proceed to
   The difference between the value of Intake Air Temperature and Coolant Temperature is -15 °C or more and 15 °C or less	A
   None of the above conditions are met	B

   HINT: 

   • -15 °C = -27 °F
   • 15 °C = 27 °F
   • When the engine is cold, the value of the Intake Air Temperature, Engine ECU Internal Temperature and Coolant Temperature should be approximately the same.

   Post-procedure1

3. None.

Result: 

A 

REPLACE ECM. Refer to  REMOVAL [06/2024 - ] 

Result: 

B 

REPLACE MASS AIR FLOW METER SUB-ASSEMBLY. Refer to  REMOVAL [06/2024 - ]
