Circuit / System Description
The cylinder deactivation system is used to deactivate 4?cylinders of the engine under light load driving conditions. The engine control module (ECM) commands the cylinder deactivation solenoids ON to deactivate engine cylinders 1, 7, 6, and 4, switching to 4?cylinders or V4 mode. The cylinder deactivation solenoids controls the oil flow to the appropriate valve lifters. The engine operates on 8 cylinders or V8 mode, during engine starting, engine idling, and medium to heavy throttle conditions.
Ignition voltage is supplied directly to the 4?cylinder deactivation solenoids. The engine control module (ECM) controls the 4?cylinder deactivation solenoids by grounding the control circuit with a solid state device called a driver.
The Cylinder Deactivation System Performance diagnostic is a test of the internal mechanical condition of the engine, during operation in V4?mode. The engine control module (ECM) determines the internal mechanical condition of the engine through the actual measured values of the mass airflow (MAF) sensor, the intake manifold absolute pressure (MAP) sensor, and the throttle position sensor. The actual measured values of the 3?sensors are then compared to the calculated values for V4?mode, stored in the ECM. If the measured values are incorrect for V4?mode, the ECM will set DTC?P3400, and will return to V8?mode operation.
