P0111 INTAKE AIR TEMPERATURE SENSOR 1 CIRCUIT RANGE/PERFORMANCE BANK 1 2
WARNING: When performing inspection mode F on a public road, pay sufficient attention to the traffic condition and give the highest priority to safe driving.
  1. Check that the battery voltage is 12 V or more and fuel remains approx. half [20 - 40 L (5.3 - 10.6 US gal, 4.4 - 8.8 Imp gal)].
  2. Using the Subaru Select Monitor, clear the memory of [Engine Control System]. Ref. to COMMON (DIAG)>CLEAR MEMORY .
  3. With the ignition switch ON (engine stopped), read the values in [Coolant Temp.] and [Intake Air Temp.].
  4. If the values from step 1) satisfy the following conditions, idle the engine for two minutes or more.

    Condition: 

    |Engine coolant temperature - Intake air temperature|≤ 5°C (9°F)

    NOTE:
    • If the conditions are not satisfied, turn the ignition switch to OFF and wait until the parameters are satisfied. 
    • Hold the select lever in "P" range or "N" range at idling. 
  5. Drive according to the drive pattern described below.

    NOTE:
    • In pattern (2), it is acceptable to decelerate to less than 80 km/h (50 MPH) or to stop the vehicle depending on the traffic conditions. Drive the vehicle at 80 km/h (50 MPH) or more until the total driving time reaches or exceeds 15 minutes. 
    • There is no given transition time between idling and cruising. 
    • Driving at constant speed only on a downhill causes smaller engine load and may result in failure to obtain a right diagnostic result. 
    • If the ignition switch is turned to OFF during inspection mode F, perform this driving cycle again after satisfying the conditions listed in the table. 
  6. Read the readiness code of [Engine Control System] using Subaru Select Monitor and check that the concerned self-diagnosis is completed. Ref. to ENGINE (DIAGNOSTICS) (H4DOTC)>ALL READINESS DIAGNOSTIC CODE(S) .
  7. Read the temporary code using the Subaru Select Monitor or general scan tool. Ref. to COMMON (DIAG)>DIAGNOSTIC TROUBLE CODE (DTC) .
