Inspection Procedure

CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO P011B)

Connect the Techstream to the DLC3.
Turn the ignition switch to ON.
Turn the Techstream on.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

Read DTCs.

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.

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

A: Go to Next Step

READ VALUE USING TECHSTREAM (INTAKE AIR TEMPERATURE)
1. Leave the vehicle for 7 hours or more.
  HINT:
  
  It is necessary 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 to ON.
4. Turn the Techstream on.
5. Enter the following menus: Powertrain / Engine and ECT / Intake Air.
6. Read the value displayed on the Techstream.
  OK: The difference between the intake air temperature and the actual outside air temperature is within 10°C (18°F) .
  
  HINT:
  
  Temperature readings on the vehicle's 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
READ VALUE USING TECHSTREAM (COOLANT TEMPERATURE)
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 and ECT / 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 )
