Hi all:

This is a follow up. After clearing the code yesterday, I drove the car on several local trips. Today, P1341 returned.

Everything looked normal at idle. Camshaft deviations were within spec and camshaft positions were normal. When spinning up the engine to 3000 RPMs, bank 1's camshaft only advanced to 8 degrees whereas bank 2 advanced to 24 degrees like yesterday.

It looks like either bank 1's solenoid is failing or the entire actuator itself. It's possible although I'd think unlikely, that the crankshaft position sensor is providing bad readings.

Is there a way to determine which part is failing? For example, can I activate the variocams with my Durametric. Or is there some other test that I can do?

Thanks
