Had the check engine light flash on a couple of weeks back with the above code (P0077: Intake Valve Control Solenoid Circuit High Bank 1), the first time I’ve had any trouble with the car in nearly 7 years ownership. The code appeared after a hot restart, car ran fine throughout.
Taking the code at face value, I flushed the bank 1 VVT actuator connector with contact cleaner and reseated it, was OK for about a week, now the code has started coming back with increasing frequency (currently after every few hot restarts). Every time it has appeared has been on a hot restart, never from cold or while driving, car is running great otherwise, I haven’t noticed any problem at all other than the check engine lamp coming on. No other DTCs stored, just this one.
My question is, does this code actually point to the bank 1 VVT actuator or is it a Jaguar specific code which points to something else? The reason I ask is that a Google search bought up a post on another forum regarding lambda sensors?
Should I just chance the relative pain to fit a new actuator or look somewhere else first?
Many thanks, Bruce.
