Drive Cycle F

DTC	Item	Condition
P0096	Intake Air Temperature Sensor 2 Circuit Range/Performance Bank 1	6 hours have elapsed since ignition switch is OFF under a completely warmed up condition. For models with block heater, at least 6 hours must have elapsed without operating the block heater.
P0111	Intake Air Temperature Sensor 1 Circuit Range/Performance Bank 1	6 hours have elapsed since ignition switch is OFF under a completely warmed up condition. For models with block heater, at least 6 hours must have elapsed without operating the block heater.

Diagnostic procedure:

With the ignition switch ON (engine stopped), read the value in «Coolant Temp.» and «IAT Sensor #11». <Ref. to DISPLAY CURRENT ENGINE DATA , OPERATION, Subaru Select Monitor.>
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.
- For CVT models, hold the select lever to "P" range or "N" range at idling, and for MT models, the shift lever in the neutral position at idling.
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.
- When the engine stops while performing drive cycle F, perform it again from the state of procedure 1).
Read the temporary code using the Subaru Select Monitor or general scan tool. <Ref. to OPERATION , Read Diagnostic Trouble Code (DTC).>
