Hi,
I have a 09 Accord 2.2 DTEC and have the 'Check System' warning light appear on my dash, which usually means the DPF is clogged.
When I brought it to my mechanic, they plugged the diagnostics machine into the car and it reported no DTC fault codes (either temp or permanent codes). We also check the DPF reading which said the dpf was not clogged (very low soot reading). We've used a number of diagostic tools on the car, including Honda's and they all say, no fault codes.
We then reset the PM (Particle Matter) reading, to essentially tell the DPF that it was clear - this worked and the warning light went off. However, once we went 500 metres up the road, the Check System warning came on again. We repeated the reset PM steps, the warning was removed, drove a little and the warning came back.
So it would seem to me that the DPF is indeed clear, but somethign is telling the car that its not.
Has anyone found this type of fault that the car reports, but the diagnostics does not ? It seems like its not really a fault, but I still have the warning light.
thanks in advance,
Aidan
