Check out any of the over 100 forum posts discussing DPFE (Diesel Particulate Filter Emission) faults on Ford vehicles—many solutions have been shared before. This is a common issue, and the root cause often involves sensor malfunctions or wiring problems in the EGR circuit.

You're welcome! Pattern failures like this are common in older Ford models. The issue has likely been discussed extensively across forums—always start with existing threads before posting repeatedly with the same code on the same vehicle.
