   Powertrain > Engine > Trouble Codes 

   Result

   Result	Proceed to
   P111C-62 and other DTCs are output	A
   P111C-62 is output	B

   HINT:

See step  2

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.
