Replacing Gs450H Vvti Solenoid

ZXSpectrum · October 4, 2014

Hi All,

Recently I have had the CEL come on in my GS450H and after plugging in the OBD2 device it shows the error P0017 Crankshaft Position Camshaft Position Correlation Bank1 Sensor B. The car does not seem to run or drive any differently although the odd time it does seem to be a bit more revvy that normal. The strange thing is that the CEL will come and go at random sometimes staying off for a week+ depending how many times I drive it. There are no other error codes which would be apparent if the timing chain had skipped a tooth and the car would be idling/driving badly but I am not getting any of that. The CEL is also just on amber and from what I have read it would have flashed and popped up another OBD error code if it has had a misfire. I do however get a random rattle on startup but that has been happening since I have owned the car and a lot of other owners have had the same with no further problems. The car is just coming up to 50K on the odo.

I will admit that I hadn't had the car serviced for a while (About 18 months out) as I do very little mileage in it (4K A year) rarely getting about 60mph on my 6 mile trip to and from work with a few other smaller journeys. But I have just had the oil and filter replaced but the light still comes on. From what I have determined it appears that I have a faulty/randomly sticking VVTi solenoid. Unfortunately at the moment I don't have the money to have it diagnosed and repaired at Lexus so I am going to have to either try and repair myself or have a local, trusted garage do it for me.

So does anyone know where the VVTi solenoids are and the procedure to replace them?

Any help would be appreciated.

I think this was the error that came up on my GS450h recently. The Lexus dealer knew about the problem and installed a software update for the ECU that fixed the problem.
