Idle speed
The idle speed setpoint is dependent on:
–the coolant temperature,
–the emission control programs,
–air conditioning requirements,
–the position of the gear lever,
–any power-assisted steering operation,
–the passenger compartment heating resistors,
–the oil temperature (engine protection),
–and lastly, the electric power balance (engine speed is increased by a maximum of 160 rpm if the battery voltage
remains below 12.7 V).
Ignition
Advance is calculated for each cylinder, and is limited between - 23˚ to + 72˚, and includes possible corrections due
to pinking.
Anti-pinking correction is the maximum advance value taken from the advance of one of the cylinders. If none of the
cylinders is pinking, this correction is zero.
Richness
For the catalytic converter to operate correctly, adjust around richness 1.
The richness regulation controlled by the upstream sensor which ensures a richness of around 1.
The upstream sensor supplies a voltage according to the image of the average engine richness: the voltage supplied
to the computer represents a Rich-Lean signal.
For the upstream sensor to be operational very rapidly, it is heated. The heating works only when the engine is
running. It is deactivated at speeds above 84 mph (140 km/h) or when the engine is under load.
The downstream sensor is also heated. The command does not activate immediately after starting the engine. It is
activated when the engine is running and has reached its operating temperature. The downstream heating sensor is
deactivated at speeds above 84 mph (140 km/h) or when the engine is under load.
Torque management
The torque structure is the system for managing engine torque. It is required for certain functions such as the
electronic stability program (ESP), automatic transmission (BVA) or sequential gearbox (BVR).
Each computer (ESP, sequential gearbox, automatic transmission) sends a request for torque via the multiplex
network to the injection computer. This intervenes between the torque requests received and the driver's requests
(made via the pedal or the cruise control/speed limiter function). The result of this intervention is the torque setpoint
to be applied. Using the torque setpoint, the structure calculates the throttle position setpoint, the ignition advance
and if the turbocharging function is present, the turbocharging solenoid valve setpoint.

STATUS
DEFINITIONPRESENT: This status indicates that there has been a fan assembly request from the
transmission.
ABSENT: This status indicates that there has not been a fan assembly request from the
transmission.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
There must be no present or stored faults.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
PRESENT
or
ABSENTThe status is PRESENT or ABSENT depending on the computer program (engine oil
temperature).
