I replaced the bank 2 camshaft hall effect sensor, Plugged in the SAI pump, and ran into another code. This is the only code existing now:

P1331 Porsche fault code 903 camshaft bank 2 driver

At idle,

spec. angle for inlet camshaft bank 2 = 0
spec. angle for inlet camshaft bank 1 = -3 to 0.6
actual angle for inlet camshaft bank 2 = -2.5 to .5
actual angle for inlet camshaft bank 1 = -8.5 to .5

The spec. angle for inlet camshaft bank 2 never changes.

So it appears the cam timing may be an issue. Can anyone out there with experience in this area comment?

Thanks - Jim
