PR089VEHICLE SPEED
PARAMETER
DEFINITIONThis parameter indicates the vehicle speed in mph (km/h).
NOTESSpecial notes:
This parameter is transmitted by the ABS computer or by the wheel speed computer.
This signal is transmitted to the injection on the multiplex network.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80
°C
In the event of a fault, carry out a multiplex network test (see 88B, Multiplexing)
Then a complete fault finding procedure of the ABS computer (see 38C, Antilock braking system) or VSU
(see 38G, Wheel speed computer).

PR130CRUISE CONTROL SETPOINT
PARAMETER
DEFINITIONThis parameter indicates the cruise control speed setpoint in mph (km/h).
NOTESThere 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.).
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80
°C
Indicates the cruise control cruising speed.
Cruise control can only be activated for a speed greater than 18 mph (30 km/h).

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.

Sensor electrical conformity
Test the air inlet circuit (from the air filter inlet to the inlet manifold tracts, run test 5 Inlet circuit check):
–air filter unit inlet not blocked and filter not clogged,
–oil vapour recirculation circuit connected correctly,
–low and high pressure air circuit sealed and not obstructed: ducts, mounting clamps present and tightened,
turbocharging pressure sensor fitted, exchanger, etc., run TEST 1 Low pressure circuit check and TEST 7
High pressure circuit sealing check
–check that the damper valve is not jammed closed.
Carry out the necessary repairs.
Check the electrical conformity of the air flowmeter:
Check the + 5 V supply of the air flowmeter on the following connection:
–3KJ of component 799.
Check the + 12 V after relay supply of the air flowmeter on the following connection:
–3FB (or 3FB3) of component 799.
Check the continuity and absence of interference resistance of the following connections:
–3DV,
–3DW, between components 120 and 799.
Flowmeter connected, vehicle ignition on and engine stopped:
Measure the voltage between connections 3DW and 3DV of component 799.
If the voltage is not between 0.3 V and 0.7 V, replace the air flowmeter, component code 799 (see MR 364 (Mégane
II), MR 370 (Scénic II), MR 385 (Modus), MR 392 (Clio III), MR 411 (New Twingo), MR 417 (Kangoo 2),
