Intake Camshaft Position Timing Over-Retarded (Bank 2)

You can drive short distances at moderate speeds. The engine will have reduced power since the intake camshaft is stuck in a retarded position. Have it diagnosed soon to prevent further engine wear.

The camshaft remains in its default retarded position when the VVT system cannot advance it. This is usually caused by low oil pressure, a clogged VVT solenoid, or blocked oil passages preventing hydraulic pressure from reaching the phaser.

Test the solenoid first since it is cheaper and easier to access. If the solenoid tests good electrically and the oil screen is clean, but commanding it does not change cam position on the scan tool, the phaser itself is likely stuck or worn.

California's OBD II regulation defines two separate VVT malfunctions (Title 13 CCR 1968.2, section (e)(13.2)). Target Error is the system failing to reach the commanded valve timing within a crank-angle or lift tolerance; Slow Response is reaching it, but too late. Both are set at the point where the deviation would push emissions past 1.5 times the FTP standards. The practical consequence is that a phaser can be moving and still be faulty — being slow is its own failure, so a component that responds correctly but sluggishly will still set a code. This is the threshold the monitor is designed around, not a description of your specific fault — the regulation says what the system must detect, not how to find it on your vehicle.
