p242f (p/filter diff pressure sendor malfunction)

**lutonmatt** · 19th April 2012, 20:30

keep getting this code come up on mine and it puts it into limp home mode
i thought it was a split inter cooler hose but changed that and its still the same

what could it be is it the filter/cat or is it the sensor thats on the bulkhead

pluged it in while i was at work today and it says the filter is 53% full

is a 08 vectra 1.9 150

Mine did the rubber pipe on top of dpf till it snapped so got a new one.I had the dp senser changed still had it going into limp mode and dpf was 58% full and could'nt do forced rejen on it so in end gutted dpf and deleted from ecu fine ever since hope you get to the bottom of it

i got to see a customer of mine who is a vaxuhall master tech but cant find his number lol

but i am hoping its a sensor or just clean the dpf as i dont have the money for a new one at the min

and how do you delete them from teh ecu can a tech 2 do it

Well i had 3 dpf's in 3 weeks and got p**d off with it gutted dpf then had no limp mode and no spannerlight but had it remapped 2 delete dpf and egr but not sure about tec2
