2 Intake air pressure
PR035: ATOMOS PRESS
Indicates the ambient baro-
metric pressure in mbar. The
sensor is incorporated in the
ECM.
If not consistent, check ATO-
MOS PRESS, INLET PRESS (in
DATA MONITOR mode) and
local ambient barometric pres-
sure, with the engine stopped
and ignition switch ON.
PR032: INLET PRESS
Indicates the pressure in the
turbocharger in mbar.
3 Air flow PR132: AIR FLOW
Mass air flow estimated by the
ECM.
NONE.
4

PR081: INLET TMP S V
Indicates the voltage delivered
by the ECM to supply the
intake air temperature sensor.
NONE.
5 Engine speed PR055: ENGINE SPEED
Indicates the engine's rota-
tional speed in rpm.
In the event of a malfunction,
