P3450: Understanding The Causes And Fixes Of Misfire In Cylinder 7
The P3450 code refers to the cylinder deactivation system in the engine. The Engine Control Module (ECM) commands the cylinder deactivation system ON to deactivate engine cylinders 1, 7, 6, and 4, switching to a V4 mode. Cylinder deactivation is accomplished by not allowing the intake and exhaust valves to open on the selected cylinders by using special valve lifters.
Deactivating the exhaust valve first allows for the capture of a burnt airfuel charge, or exhaust gas charge, in the combustion chamber.
Switching between V8 and V4 modes is accomplished in less than 250 milliseconds, making the transitions seamless and transparent to the vehicle operator.
