●tooth/camshaft signal consistency fault finding procedure
The VVT is controlled at the lower stop and the camshaft angle measurement is forced to the requested setpoint.
A first program called Memo phasing is applied to phase the engine management on starting according to the data
recorded at the last setting. It is therefore essential to wait until the end of the "powerlatch" phase (computer self-
supply phase enabling data to be saved which lasts for approximately 30 seconds) before starting any operations.
Then, a second program confirms the first decision. It is based on torque analysis.
Air supply
The idle speed regulator performs all of the calculations required for physical control of the idle speed actuator: the
motorised throttle. The functional component of the regulator is adaptive (variation programming and ageing).
If the idle speed regulation conditions are met, the status ET054 Idle speed regulation is "Active", and the idle
speed regulator continually positions the motorised throttle to maintain the engine speed at its idle reference value.
The motorised throttle opening ratio necessary to comply with the speed setpoint is then given by parameter
PR091 Idle speed regulation theoretical OCR.
The PR090 Idle speed regulation programming value is a stored parameter designed to "program" engine
variations and engine wear and tear for the idle speed regulator. The programming is carried out only when the
engine is idle and warm, and no electrical consumer (air conditioning, fan assembly, power assisted steering) is
operating. Therefore it adjusts slowly.

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.
