ZX, thanks for the reply. I changed both the CamShaft sensors and still shows up and after a few months now I have been watching it and noticed something strange.....The light always comes on when the fuel tank drops to just above 3/4 full and goes off again when it gets to just over 1/4 tank full. Very strange and the car drives and runs fine, no excess revvyness at all. I had read somewhere about the pressure in the fuel tank causing problems because the seal on the fuel cap was not right. My Lexus dealer gave me the same line "strip the engine down to check the timing chain" and it would cost about €2,500 to do it!!! I might just get two new VVTI solenoids and see how it goes from there. The car runs and drives like a dream even though the error is there.

Hi folks, can anyone give me some advice on this? I am getting a P0017 Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor B error on my 2007 GS450H. I have replaced the main battery (needed to be done) and replaced both the camshaft sensors and just had it serviced. It had the recall done for the valve issue as well and a software upgrade which they thought would resolve the issue. The car drives perfect with no rough idling or any other symptoms and no other faults are showing. The CEL light comes on after a few days after I reset the error and can go off again of its own accord. Any ideas folks? Hoping it isn't a timing chain issue.
