P242F - DPF pressure sensor malfunction
P2279 - Air induction component leaking.
This vehicle has been to many garages having multiple parts bolted on and the customer has lost track of what parts have actually been fitted.
My worry is that actual values show DPF differential pressure set at -2kpa with the engine off or idling.
At WOT it goes up to about 6kpa
I have carried out a pressure sensor relearn and I have removed it and tested with mityvac and it seems to work ok.
The 242F has cleared now and hasnt yet returned but I am still getting P2279 when throttling off on at high speed on a bypass
