MONITOR DESCRIPTION
When the sensor output voltage remains at less than 0.3 V, or more than 4.7 V for more than 4 seconds, the ECM
stores a DTC.

CONFIRMATION DRIVING PATTERN
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).
3.
Turn the ignition switch off and wait for at least 30 seconds.
4.
Turn the ignition switch to ON and turn the Techstream on.
5.
Start the engine.
6.
Idle the engine for 10 seconds or more [A].
7.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [B].
8.
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.
9.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
10.
Input the DTC: P0365, P0367, P0368, P0390, P0392 or P0393.
11.
Check the DTC judgment result.
TESTER
DISPLAY
DESCRIPTION
NORMAL
DTC judgment completed
System normal
ABNORMAL
DTC judgment completed
System abnormal
INCOMPLETE
DTC judgment not completed
Perform driving pattern after confirming DTC enabling conditions
N/A
Unable to perform DTC judgment
HINT:
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A, perform steps [A] through [B] again.
12.
If no pending DTC is output, perform a universal trip and check for permanent DTCs
.
13.
1UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0365,P0367,...
HINT:
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.
WIRING DIAGRAM
INSPECTION PROCEDURE
HINT:
Read freeze frame data using the Techstream. Freeze frame data records the engine condition when
malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was
moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other
data from the time the malfunction occurred.
Bank 1 refers to the bank that includes the No. 1 cylinder*.
*: The No. 1 cylinder is the cylinder which is farthest from the transmission.
Bank 2 refers to the bank that does not include the No. 1 cylinder.
Sensor 1 refers to the sensor closest to the engine assembly.
Sensor 2 refers to the sensor farthest away from the engine assembly.
PROCEDURE
1.
CHECK HARNESS AND CONNECTOR (SENSOR POWER SOURCE)
