Hi John, I think that P1554 is a camshaft position actuator error. You may check the cabling of the sensor on bank 1.
Thanks Stef, would that be the cabling to the phase sensor or that goes into the variator on top of the cam cover? also when looking at the engine from the back of the car facing forward which side is bank1?
This fault indicates the solenoid for the intake camshaft variator has failed. If you locate the connector and separate it, you will find it saturated with engine oil. It may even be full enough to be leaking oil out of the connector and onto the cam cover.
My recommendation is to have all (4) variator solenoids replaced now, which is accompanied by a cam cover reseal.
Thanks Josh, I've had exactly the same issue, the solenoid/sensor was saturated with engine oil and was leaking on the cam cover. P1554 appeared then. Easy to replace. Since then, it never happened again. This issue seems to be quite common on the F430.
It is common on the 430, also on the 599's and Maserati 4200 engines. They all share the same part, with different harness lengths. Hopefully at some point they perfect the design so it isn't such a common problem.
Also one other q, I'm assuming that I would just lose variable control of the camshaft and not cause any damage driving it? I had to drive it to the dealer today which was about 60 miles, apart from the light it didn't feel that different to normal to be honest although I was taking it easy.
So spoke to the dealer and it is the variator control solenoid on bank2 that's the issue, they've cleaned the connector and it's working for now. My question is that I'm pretty sure I could do the job myself, I need the car to work this weekend then i'd have time to do the job. In my workshop manual I have the procedure to replace the solenoids but I don't have the procedure to remove the cam cover, I know it won't be difficult but Id just like to see it to make sure there are no major obstacles. Anyone have a copy of the cam cover removal procedure B3.02(Stef? )
