   Result	Proceed to
   P011B	A
   P011 Band other DTCs	B

   HINT

   If any DTCs other than P011B are output, troubleshoot those DTCs first

B: GO TO DTC CHART  (See DIAGNOSTIC TROUBLE CODE CHART )

A: Go to next step 

1. Leave the vehicle for 7 hours or more

   HINT.

   It is necessary to leave the vehicle for 7 hours or more to allow conditions similar to the DTC detection conditions.

2. Connect the Techstream to the DLC3.
3. Turn the engine switch on (IG)
4. Turn the Techstream ON.
5. Enter the following menus. Powertrain / Engine / Data List/ Intake Air.
6. Read the value displayed on the Techstream

   OK: Difference between the intake air temperature and the actual outside air temperature is within 10°C (18°F). 

   HINT.

   Temperature readings on the vehicle outside temperature gauge (if equipped) are not suitable for comparing to the intake air temperature reading The outside temperature gauge has a significant delay built in to prevent temperature swings from being displayed on its display. Use an accurate thermometer to determine the outside air temperature.

NG: REPLACE MASS AIR FLOW METER  (See REMOVAL )

OK: Go to next step 

1. Connect the Techstream to the DLC3
2. Turn the engine switch on (IG)
3. Turn the Techstream ON
4. Enter the following menus Powertrain / Engine / Data List / Coolant Temp.
5. Read the value displayed on the Techstream.

   OK: The difference between the coolant temperature and the actual outside air temperature is within 10°C (18°F). 

   HINT

   If the result is not as specified, check if there are heat sources such as a block heater in the engine compartment.

NG: REPLACE ENGINE COOLANT TEMPERATURE SENSOR  (See REMOVAL )

OK: REPLACE ECM  (See REMOVAL )
