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

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch on (IG).
3. Turn the tester on.
4. Enter the following menus: Powertrain / Engine and ECT / Trouble Code.
5. Read the DTCs.

   Display (DTC Output)	Proceed to
   P011B	A
   P011B and other DTCs	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 allow conditions similar to the DTC detection conditions.

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

   OK

   The intake air temperature and the outside air temperature are within 10°C (50°F) of each other.

   HINT: 

   Temperature readings on the vehicle's outside temperature gauge (if equipped) are not suitable for comparing to the IAT 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.

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch on (IG).
3. Turn the tester ON.
4. Enter the following menus: Powertrain / Engine and ECT / Data List / Coolant Temp.

   OK

   The coolant temperature and the outside air temperature are within 10°C (50°F) of each other.

   HINT: 

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