PR132AIR FLOW
PARAMETER
DEFINITIONThis parameter indicates the inlet air flow in mg/st.
NOTESSpecial notes:
For vehicles that are not equipped with a flowmeter, the air flow is estimated using
the following parameters:
–Inlet air temperature,
–The atmospheric pressure,
–The EGR valve position,
–The fuel flow,
–The engine speed.
There must be no faults present.
Perform this fault finding procedure:
–after finding an inconsistency in the parameter,
–or after a customer complaint (lack of power, smoke etc.).
See the Wiring diagrams Technical Note for the vehicle.
Conformity check with engine stopped and ignition on.
Indicates the inlet air flow PR132 ≈ 0 mg/st.
Conformity check: Engine running at idle speed and engine coolant temperature > 80
°C
Indicates the inlet air flow PR132 ≈ 200 mg/st.
