CONFIRMATION DRIVING PATTERN
3UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P011B; Engin...
Connect the Techstream to the DLC3.
1.
Turn the ignition switch to ON and turn the Techstream on.
2.
Clear DTCs (even if no DTCs are stored, perform the clear DTC operation) [A].
3.
Turn the ignition switch off.
4.
With the engine stopped, leave the vehicle as is for 7.5 hours or more [B].
5.
Start the engine and wait 60 seconds or more [C].
6.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [D].
7.
Read the Pending DTCs.
HINT:
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
8.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
9.

If no pending DTC is output, perform a universal trip and check for permanent DTCs
.
HINT:
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.
12.
INSPECTION PROCEDURE
PROCEDURE
1.
CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO P011B)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON and turn the Techstream on.
(c) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
(d) Read DTCs.
RESULT
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
2.
READ VALUE USING TECHSTREAM (INTAKE AIR TEMPERATURE)
(a) 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.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON and turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / All Data / Intake Air.
(e) 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:
3UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P011B; Engin...
OK
Temperature readings on the vehicle 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.
Perform "Inspection After Repair" after replacing the mass air flow meter
.
NG
REPLACE MASS AIR FLOW METER
3.
READ VALUE USING TECHSTREAM (COOLANT TEMPERATURE)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON and turn the Techstream on.
(c) Enter the following menus: Powertrain / Engine and ECT / All Data / Coolant Temp.
(d) 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 heat sources such as a block heater in the engine
compartment.
Perform "Inspection After Repair" after replacing the engine coolant temperature sensor
.
NG
REPLACE ENGINE COOLANT TEMPERATURE
