When it drops into "limp mode" are the revs limited to around the 4-4.5K mark?

not that ive noticed, the sport light goes out and slow to pull away, seems like in 3rd gear.
I will try later and see if revs limited. What do you think it could be?

If revs are limited, sure sign it`s the cam sensor. Been well known to put car in limp mode as well as throw spurious codes

Those codes sound like gearbox codes and not engine codes. What did you read them with, and were there any codes in the engine ECU?

The sluggish pulling away sounds like the automatic gearbox being in limp home (pulling away in 3rd gear). I can't find an exact match for the codes (Wasn't P1740 and P1781, by any chance?), but they appear to relate to the CAN connection between gearbox and engine ECU.

A cam sensor failure is common on the 2.2 and they can throw up problems in the gearbox as the data from the engine ECU becomes unreliable when the sensor fails.

I would want to see some codes from the engine ECU before being certain that it's the cam sensor.

Does it take a little longer cranking on the starter motor than usual before it starts? This is also a symptom of cam sensor failure.
