One of the banks for my engine seems to jump between 126 and 70 degrees every half second on the sensor reading. Could it be a sensor issue or a physically worn actuator? I’ve replaced the solenoid already. It’s only for the intake valve readings. Exhaust is a solid 120deg

Also debating if it’s the camshaft being out of time or the chain being stretched.

I’m unsure if there’s a VANOS position sensor since I can’t find any info on it. Seems like position is derived from camshaft readings.

The other bank stays at a solid 126deg at idle.
