DTC P011B: Engine Coolant Temperature / Intake Air Temperature Correlation: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine / Trouble Codes.
5. Read the DTCs.

   Result

   Result	Proceed to
   DTC P011B is output	A
   DTC P011B and other DTCs are output	B

   HINT: 

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

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 create conditions similar to the DTC detection conditions.

2. Connect the Techstream to the DLC3.
3. Turn the ignition switch to ON.
4. Turn the Techstream on.
5. Enter the following menus: Powertrain / Engine / Data List / All Data / 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 outside temperature gauge of the vehicle (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 swings in the temperature display. Use an accurate thermometer to determine the outside air temperature.

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine / Data List / All Data / 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 that there are no heat sources such as a block heater in the engine compartment.
