DTC P011B: Engine Coolant Temperature / Intake Air Temperature Correlation [10/2014 - 10/2015]: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ECT / 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.

Result: 

B 

GO TO DTC CHART 

(Refer to DIAGNOSTIC TROUBLE CODE CHART [10/2014 - 10/2015] )

Result: 

A 

See step  2

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 power switch on (IG).
4. Turn the Techstream on.
5. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / Intake Air.
6. Read the value displayed on the Techstream.

   Standard

   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.
   • Perform "Inspection After Repair" after replacing the mass air flow meter sub-assembly (Refer to INITIALIZATION [10/2014 - ] ).

Result: 

NG 

REPLACE MASS AIR FLOW METER SUB-ASSEMBLY 

(Refer to REMOVAL [10/2014 - ] )

Result: 

OK 

See step  3

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

   Standard

   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.
   • Perform "Inspection After Repair" after replacing the engine coolant temperature sensor (Refer to INITIALIZATION [10/2014 - ] ).

Result: 

OK 

REPLACE ECM 

(Refer to REMOVAL [10/2014 - ] )

Result: 

NG 

REPLACE ENGINE COOLANT TEMPERATURE SENSOR 

(Refer to REMOVAL [10/2014 - ] )
