P3405: The Lowdown On Your Engine’s Camshaft Position Sensor
The P3405 code relates to the cylinder deactivation system in the engine. The system deactivates cylinders 1 and 7 on the left bank, and cylinders 4 and 6 on the right bank, switching to a V4 mode. The system deactivates the intake and exhaust valves to open on the selected cylinders by using special valve lifters.
The deactivation lifters contain spring-loaded locking pins that connect the internal pin housing of the lifter to the outer housing. The P3405 code indicates an issue with the exhaust valve control circuit for cylinder 1.
