Hello, I just wondered if anyone has had this issue / solved it.

I have a 52 reg D5 XC90 auto which has an intermittent power loss which lasts half a second and then back to normal. This happens under normal cruise at higher speeds. Some days this doesn't happen and others it happens a number of times. The associated code which I clear each time and then appears in memory after the fault is 300A "camshaft position (CMP) sensor, faulty signal". I've changed the sensor for a new one and the symptoms remain the same. I presume this therefore means there is a fault in the wiring to the sensor.

I'd be grateful is anyone has a wiring diagram for this sensor to the ECU or has solved this problem in the past.

Thanks for any help.
