Exhaust Pressure Differential Sensor: Description and Operation
DESCRIPTION
The Exhaust Differential Pressure Sensor is remotely mounted on the transmission housing. Two pressure tubes measure pressure before and after the
Diesel Particulate Filter (DPF)/Diesel Oxidation Catalyst (DOC). The sensor is critical for fail-safe of regeneration strategy, because it interprets high
pressure drops as possible high soot loads.
