Inspection Procedure
- CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO P011B)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to the ON position.
- Turn the Techstream on.
- Enter the following menus: Powertrain/Engine and ECT/Trouble Codes.
- Read the DTCs.
Result
RESULT CHARTResult Proceed to P011B A P011B and 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
- READ VALUE USING TECHSTREAM (INTAKE AIR TEMPERATURE)
- 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.
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Powertrain/Engine and ECT/Intake Air.
- Read the value displayed on the Techstream.
OK:
Difference between the intake air temperature and the actual outside air temperature is within 10°C (50°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
- Leave the vehicle for 7 hours or more.
- READ VALUE USING TECHSTREAM (COOLANT TEMPERATURE)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Powertrain/Engine and ECT/All Data/Coolant Temp.
- Read the value displayed on the Techstream.
OK:
The difference between the coolant temperature and the actual outside air temperature is within 10°C (50°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 )
