The different ial pres s ure s ensor i s located i n t he engi ne compart ment , on t he lower RH si de of the bul khead. The sens or islocated on two st uds and s ecured wit h nuts .
The different ial pres s ure s ensor i s us ed by the DPF software t o monit or the condit ion of t he DPF. Two pi pe connecti ons ont he sens or are connect ed by pipes t o t he inlet and out let ends of t he DPF. The pipes all ow t he s ens or to measure t he inletand outl et press ures of t he DPF.
As t he amount of parti culat es t rapped by the DPF increases , t he pres sure at t he inlet s i de of the DPF i ncreas es i ncomparis on t o t he DPF outl et . The DPF s oft ware us es t his compari son, in conduct ion wit h other data, t o calculate theaccumulat ed amount of trapped part iculat es.
By meas uri ng the press ure difference between t he DPF i nl et and out let and t he DPF t emperature, the DPF s oftware candetermine i f the DPF is becoming bl ocked and requires regenerat ion.
Differential Particulate Filter Temperature Sensors

Quick start
R
The air distribution and blower controls can be
operated to override the automatic settings.
This will extinguish the appropriate LED in the
AUTO control.
Temperature selection (Automatic system)
Rotate the control 1 to adjust the temperature
for the respective side of the passenger
compartment.
Blower speed (Automatic systems)
Rotate the blower control 2 to adjust airflow
through the vents. LEDs will illuminate to
indicate which of the ei ght possible speeds is
currently selected.
Air distribution contro l (Automatic systems)
Press to select the desi red distribution setting.
An LED will illumina te in the switch.
Front screen and side window vents
Face level vents
Foot level vents
More than one setting can be
selected to achieve the desired
distribution. Off (Automat
ic systems)
Press to switch the system off. An
LED will illuminate in the switch to
show this condition.
Press again to return the system to its previous
operating mode. The system will also be
reactivated by using the AUTO, blower speed,
air distribution or defrost controls.
Defrost mode (Automatic systems) Press to remove frost or heavy
misting from the front screen. The
system will automatically adjust the
blower output for maximum clearing, in
addition the front and rear screen heaters will
be activated.
Press again to switch off defrost mode. The
screen heaters will remain on.
Heated screens Press to operate. An LED in the
switch will illuminate whilst
operating.
The heaters will automatically
switch off after a preset interval.
Air recirculation Press once to activate air
recirculation. An LED will illuminate
in the switch. Press again to return
to fresh air intake.
Economy mode Press to put the system into
economy mode. An LED will
illuminate in the switch to show this
condition.
In economy mode air conditioning is switched
off. This reduces the load on the engine,
thereby improving fuel consumption.
Recommended mode
Select AUTO as the normal operating mode.
This will help prevent window misting and
odours from the climate control system.
Operating note
On the automatic system, it is not possible to
achieve a temperature differential of more
than 4°C (7°F) betwee n the left and right.
