I have a 2016 Jaguar XE 2.0L diesel automatic, which is showing the following error codes:

P0079 Exhaust valve control circuit low (bank 1)
P0598 Thermostat heater control - circuit low
P0342 Camshaft position sensor A - circuit low input (bank 1 or single sensor)

Anyone know what this combination of error codes means and what work will be required to clear them.

Thanks.
