MONITOR DESCRIPTION
Fuel System Air Fuel Ratio Cylinder Imbalance Monitor
The ECM uses the air fuel ratio sensor (sensor 1) and crankshaft position sensor to monitor the difference in air fuel ratios between the cylinders caused by differences in injection volumes between the cylinders, leakage in the intake or exhaust system, etc.
When the air fuel ratios of the cylinders are lean or rich with respect to each other, the ECM determines that there is a malfunction, illuminates the MIL and stores a DTC.
Air Fuel Ratio Sensor (Sensor 1) Monitoring Method: P11EA00 (for port injection), or P219A00 (for direct injection) is stored primarily when a rich side imbalance is detected.
When the system detects a difference in air fuel ratios between the cylinders due to fluctuation in the air fuel ratio sensor (sensor 1) output over 1 engine cycle (2 crankshaft revolutions), the system determines that there is a problem.
Crankshaft Position Sensor Monitoring Method: P11EC00, P11ED00 and/or P11EE00 (for port injection), or P219C00, P219D00 and/or P219E00 (for direct injection) are stored primarily when a lean side imbalance is detected.
The system monitors the engine speed variation and when the variation becomes large, the system determines that there is a difference in air fuel ratios between the cylinders, which it determines to be a problem.

-
[A] to [D]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

- Perform driving pattern after confirming DTC enabling conditions
HINT:
- If the judgment result is NORMAL, the system is normal.
- If the judgment result is ABNORMAL, the system has a malfunction.
- If the judgment result is INCOMPLETE, perform the confirmation driving pattern and check the judgment result again.
-
[A] to [K]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
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.
- When any air-fuel ratio imbalance is detected, the ECM will perform air-fuel ratio feedback control to make the air-fuel ratio close to the stoichiometric level. This may result in an air-fuel ratio imbalance of normal cylinders and DTCs may be stored.
- Whether malfunctions occur on the port injection side or direct injection side cannot be determined solely by the output DTCs. Inspect every suspected area even if it is not related to the DTCs.
- Read Freeze Frame Data using the GTS. 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.

When the "Control the Injection Volume" Active Test is selected (injection volume is 0%), if a misfire count increases, proceed to step 6 (CHECK INTAKE SYSTEM).
(c) Check the misfire counts (Misfire Count Cylinder #1 to #4) while decreasing the injection volume in 5% increments.
The cylinder whose misfire count has not increased can be assumed to be running rich. Therefore, perform inspections while focusing on that cylinder.
