ON-BOARD DIAGNOSTIC

Sending Intermittent Monitoring System Test Results (Mode 06)

• The items supported by the sending intermittent monitoring system are shown in the table.

Sending Continuous Monitoring System Test Results (pending code) (Mode 07)

• These appear when a problem is detected in a monitored system.

1 drive cycle type

• If any problems are detected in the first drive cycle, pending codes will be stored in the PCM memory, as well

as DTCs.

• After pending codes are stored, if the PCM judges that the system is normal in any future drive cycle, the PCM

deletes the pending codes.

2 drive cycle type

• The code for a failed system is stored in the PCM memory in the first drive cycle. If the problem is not found in

the second drive cycle, the PCM judges that the system returned to normal or the problem was mistakenly

detected, and deletes the pending code. If the problem is found in the second drive cycle too, the PCM judges

that the system has failed, and stores the pending codes, and the DTCs.

• After pending codes are stored, if the PCM judges that the system is normal in any future drive cycle, the PCM

deletes the pending codes.

End Of Sie

DTC

A6E397018881T04

• Detection logics and conditions are as shown below.

CMP Timing

CMP actuator circuit malfunction (P0010)

• PCM monitors OCV voltage. If PCM detects OCV control voltage (calculated from OCV) is above or below the

threshold voltage (calculated from battery positive voltage), PCM determines that OCV circuit has a

malfunction.

CMP timing over-advanced (P0011)

• Actual valve timing is over-advanced by 30 deg. from target valve timing when the OCV is controlled within the

maximum valve timing retard condition.

CMP timing over-retarded (P0012)

• Actual valve timing is over-retarded by 5 deg. from target valve timing for 5 s when the OCV system control is

within feed-back range.

Oxygen Sensor Heater

Front HO2S heater circuit low input (P0031)

• The PCM monitors the front HO2S heater control signal at the PCM terminal 4A. If the PCM turns the front

HO2S heater off but front HO2S heater circuit has low voltage, the PCM determines that the front HO2S heater

circuit has a malfunction.

Front HO2S heater circuit high input (P0032)

• The PCM monitors the front HO2S heater control signal at the PCM terminal 4A. If the PCM turns the front

HO2S heater on but front HO2S heater circuit has high voltage, the PCM determines that the front HO2S

heater circuit has a malfunction.

Rear HO2S heater circuit low (P0037)

• The PCM monitors the rear HO2S heater control signal at the PCM terminal 4D. If the PCM turns the rear

HO2S heater off but rear HO2S heater circuit has low voltage, the PCM determines that the rear HO2S heater

circuit has a malfunction.
