Accelerator pedal po-
sition
ACCEL/PDL POS
0%= ACCEL/PDL POS < 100%
Indicates the percentage of the
pedal position between no load
and full load position
In the event of a malfunction, per-
form the trouble diagnosis for APP
SENSOR (DTC P0225, and P2120)
and SENSOR POWER SUPPLY
(DTC P0641 and P0651).
5
Inlet air temperature
INLET AIR TEM
Indicates the intake air tempera-
ture in
°
C. This information is pro-
vided by the IAT sensor.
In the event of a malfunction, per-
form the trouble diagnosis for DTC
P0110 IAT SENSOR.
6
Fuel pump tempera-
ture
FUEL TEMP
Close to ambient temperature
(cold engine).
Indicates the fuel pump tempera-
ture in
°
C.
In the event of a malfunction, per-
form the trouble diagnosis for DTC
P0180 FTT SENSOR.
7
Intake air pressure
ATOMOS PRESS
700 mbar < ATOMOS PRESS <
1100 mbar
Indicates the ambient barometric
pressure in mbar. The sensor is
incorporated in the ECM.
If not consistent, check ATOMOS
PRESS = INLET PRESS = local
ambient barometric pressure, with
the engine stopped and ignition
switch ON.
INLET PRESS
Indicates the pressure in the tur-
bocharger in mbar.
8
Fuel rail pressure
RAIL PRESSURE
Approximately 0 bar
Indicates the fuel rail pressure in
bar of the diesel fuel in the fuel
rail.
This pressure is supplied by the
fuel rail pressure sensor.
In the event of a malfunction, per-
form the trouble diagnosis for DTC
P0190 and P1089 FRP SENSOR.

Engine immobilizer
ENGINE IMMOBI
INACTIVE
Indicates the status of the immo-
bilizer system.
• INACTIVE: The ECM has rec-
ognized the immobilizer code
transmitted by the Intelligent
Key unit or BCM.
• ACTIVE: The ECM does not
recognize the immobilizer code
transmitted by the Intelligent
Key unit or BCM.
If ACTIVE, perform the trouble diag-
nosis for NATS.
11
Vehicle speed
VEHICLE SPEED
0 km/h (mph)
Indicates the vehicle speed in km/
h (mph). This parameter is trans-
mitted by the “ABS actuator and
electric unit (control unit)” or com-
bination meter via CAN communi-
cation line.
Perform the trouble diagnosis for
CAN communication line. Perform
the trouble diagnosis for “ABS actu-
ator and electric unit (control unit)”
or combination meter.
