MONITOR DESCRIPTION
Fuel System Air Fuel Ratio Cylinder Imbalance Monitor
The ECM uses the air fuel ratio sensor, crankshaft position sensor and EGR valve assembly to monitor the difference in air fuel ratios between the cylinders caused by differences in fuel injection volume 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.
EGR Port Clogged Monitoring Method: P10AA00 is stored primarily when a rich side imbalance for clogged EGR port is detected.
By comparing the air fuel ratio when EGR valve is open and closed, a clog in an EGR port can be detected. If an EGR port is clogged when the EGR valve is open, the ECM will store a DTC.
Air Fuel Ratio Sensor Monitoring Method: P219A00 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 output over 1 engine cycle (2 crankshaft revolutions), the ECM determines that there is a malfunction.
Crankshaft Position Sensor Monitoring Method: P219C00, P219D00, P219E00 and/or P219F00 are stored primarily when a lean side imbalance is detected.
The system monitors the engine speed variation and when the variation becomes large, the ECM determines that there is a difference in air fuel ratios between the cylinders, which it determines to be a malfunction.

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 air fuel ratio. This may result in an air fuel ratio imbalance of normal cylinders and DTCs may be stored.
- 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.
