Why does my GPF say exhaust filter limit reached?
Some of the Ford forums suggest that this error could be due to a sensor malfunction however we’ve seen comments with increasing frequency from owners with cars under a year old. Could it be that like a DPF, the GPF requires the same sort of conditions for regeneration?
What happens when the exhaust filter is reached?
This in turn raises the temperature of the GPF to around 400c – 700c, igniting the soot contained within the filter. In conditions where this is not possible, the vehicles engine management systems alter timing causing it to run lean. This “lean” burn increases oxygen and therefore GPF operating temperatures, allowing regeneration to occur.
Is the GPF particulate filter maintenance free or maintenance free?
We were surprised to see comments by Ford owners on our GPF / Gasoline Particulate filter FAQ asking about the error “ Exhaust filter limit reached. drive to clean now “. We were made to believe that unlike the DPF filter, the GPF was a “maintenance free” filter which would “clean” itself under normal driving conditions.
