P244A fault code: what it means

P244A: DPF differential pressure is too low (diesels).

Engine and gearbox (powertrain) · Costly if missed

Usual causes, most likely first

faulty DPF pressure sensor
blocked or disconnected pressure sensor pipes
exhaust leak before the DPF
DPF removed or cracked

P244A by make

Ford

DPF differential pressure too low: the pressure drop across the filter is lower than expected.

Usual causes: split or disconnected DPF pressure sensor hose; faulty DPF pressure sensor; cracked or hollowed-out DPF

GWM

DPF differential pressure too low.

Usual causes: broken or split DPF sensor pipe; faulty DPF pressure sensor; cracked DPF

Holden

DPF differential pressure too low: the pressure drop across the filter is less than expected.

Usual causes: split or disconnected sensor pipe; faulty DPF pressure sensor; cracked or hollowed-out DPF

Land Rover

DPF differential pressure too low. Often follows a split intercooler pipe or DPF sensor pipe problem; restricted performance above 2,000 rpm.

Usual causes: split or disconnected DPF pressure sensor pipe; faulty DPF differential pressure sensor; cracked DPF or exhaust leak

Before you clear it

Write the code down or photograph the scanner first. A code that comes straight back after clearing points to a fault that is still there. A car whose codes were cleared just before you arrived may be hiding one: the scanner's readiness monitors show "not ready" for a while after codes are cleared.

Researched by Credov from manufacturer and workshop sources. A fault code points to where a fault may be; a workshop confirms it with a diagnosis. Browse all fault codes.
