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.

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?

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.

What should the temperature of the exhaust filter be?

Until we have any further information we can only suggest that a blast up your local dual carriageway while focusing on periods of throttle off deceleration from high revs. Deceleration increases the amount of oxygen following through the engine and exhaust system. This, in turn, raises the temperature of the GPF to around 400c – 700c

Wait until it gets down to 30% or lower and then add 2.5 gallons. You won’t hurt anything letting it get down to even 10% or below. You cannot however add 5 gallons, unless perhaps you were totally empty. Update! The dealer said the truck had 235% soot level in the dpf and wouldnt go into Regen mode by itself.

What causes the exhaust filter to run lean?

Deceleration increases the amount of oxygen following through the engine and exhaust system. 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.

When does the exhaust filter change to regeneration?

Once you drive long enough for the exhaust to be hot enough, this will change to “Exhaust System Regeneration in Process. Continue Driving” – and that message will stay on until the regeneration is complete (about 10-15 minutes in my experience). I’ve seen this series of messages in my 2014 GC several times.
