MONITOR DESCRIPTION
Abnormality in Output Current Comparison between Air Fuel Ratio Sensor (Sensor 1) and Air Fuel Ratio Sensor (Sensor 2) during Fuel Cut
Comparing the averaged output values during fuel cut for air fuel ratio sensor (sensor 1) and air fuel ratio sensor (sensor 2), if the difference between these two is outside the normal range, the ECM illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN
-
Connect the Techstream to the DLC3.
-
Turn the ignition switch to ON.
-
Turn the Techstream on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the ignition switch off and wait for at least 30 seconds.
-
Turn the ignition switch to ON.
-
Turn the Techstream on.
-
Enter the following menus: Powertrain / Engine / Monitor / Current Monitor.
-
Check that Catalyst Efficiency / Current is Incomplete.
-
Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher with the shift lever in P or neutral [A].
HINT:
In order to keep the idle stable, turn off the A/C and all other electric loads and do not perform any shift operations.
-
Drive the vehicle at approximately 75 km/h (46 mph) for 10 minutes or more [B].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
Drive the vehicle while keeping the engine load as constant as possible.
-
With the shift lever in M or 2nd gear, drive the vehicle at 75 km/h (46 mph), and then decelerate the vehicle by releasing the accelerator pedal for 10 seconds or more to perform the fuel-cut [C].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
-
Repeat step [C] 2 times or more in one driving cycle.
-
Enter the following menus: Powertrain / Engine / Trouble Codes / Pending [D].
-
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.
-
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
-
Input the DTC: P00D562.
-
Check the DTC judgment result.

CAUTION / NOTICE / HINT
HINT:
-
Sensor 1 refers to the sensor closest to the engine assembly.
-
Sensor 2 refers to the sensor farthest away from the engine assembly.
-
Read Freeze Frame Data using the Techstream. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. 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.
PROCEDURE
1.
|
CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P00D562)
|
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
(e) Read the DTCs.
Powertrain > Engine > Trouble Codes
