Cam Sensor P3007

Relay Voltage Terminal P1601.

Are these major or minor problems. any help would be of assistance, cheers. 

P1601 is a fault with the Relay for Supply Voltage Terminal 30 (J317). It's on the central electronics module under the dash.

P3007 is a fault with Camshaft Position Sensor (G40).

In theory, a fault with the T30 relay could cause the Camshaft fault.

Do the faults come back if you clear them?

just cleared them earlier, see what happens. cheers. is the relay a pain to get too.
