DTC DETECTION LOGIC
When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crank-
shaft position (CKP) sensor (POS) signal to vary, ECM can determine that a misfire is occurring.
The misfire detection logic consists of the following two conditions.
1. One Trip Detection Logic (Three Way Catalyst Damage)
On the 1st trip that a misfire condition occurs that can damage the three way catalyst (TWC) due to over-
heating, the MI will blink.
When a misfire condition occurs, the ECM monitors the CKP sensor signal every 200 engine revolutions
for a change.
When the misfire condition decreases to a level that will not damage the TWC, the MI will turn off.
If another misfire condition occurs that can damage the TWC on a second trip, the MI will blink.
When the misfire condition decreases to a level that will not damage the TWC, the MI will remain on.
If another misfire condition occurs that can damage the TWC, the MI will begin to blink again.
2. Two Trip Detection Logic (Exhaust quality deterioration)
For misfire conditions that will not damage the TWC (but will affect vehicle emissions), the MI will only light
when the misfire is detected on a second trip. During this condition, the ECM monitors the CKP sensor
signal every 1,000 engine revolutions.
A misfire malfunction can be detected on any one cylinder or on multiple cylinders.

< FUNCTION DIAGNOSIS >[K9K]
FUEL INJECTION CONTROL
energy returned by the piezo actuator is reused, which keeps down the amount of energy that has to be sup-
plied for the next injection process.
Engine Synchronisation
One of the determining factors for fuel injection control is knowing the position of each of the pistons in their
respective cylinders at all times.
The angular position is measured by means of a magneto-inductive sensor which is excited by the teeth
machined onto the flywheel; this is known as the crankshaft position sensor. The flywheel has 60 teeth, each 6
degrees apart; 2 of these teeth are missing to form a notch.
A second sensor (Hall-effect sensor), stimulated by a tooth machined onto the camshaft, which turns at half
the engine speed, provides a signal relating to the progress of the injection cycle. Indeed, when the piston of
cylinder 1 is at top dead centre (TDC), either at the end of the compression stroke or at the end of the exhaust
stroke, the camshaft position sensor enables a distinction to be made between these two states.
By comparing the signals from these two sensors, the computer is able to provide all its systems with synchro-
nisation parameters, namely: the angular position of the flywheel, engine speed, the number of the active fuel
injector and the progress of the injection cycle.
This module also supplies the system with the rotation speed signal.
The camshaft position sensor is only used when starting the engine. As soon as the engine is running by itself
(not being cranked by the starter), the signal provided by the crankshaft position sensor is sufficient. If the
camshaft position sensor should fail while the engine is running, this will not affect the operation of the engine.
Quantity of Fuel Injected and Control of Start of Injection
 The parameters for controlling injection are, for each cylinder, the quantity to be injected and the start of
injection. These are calculated by the ECM from the following information:
- Engine speed.
- Accelerator pedal position.
- Turbocharge air pressure.
- Engine coolant temperature.
- Intake air temperature.
- Fuel pump temperature.
- Mass air flow.
- Pressure of fuel in the rail.
Station to Station Flow Regulation
The aim of this regulation process is to facilitate smooth engine operation by compensating for the system
variations (fuel injectors, compression rate, etc.) which affect the torque generated by each cylinder during
combustion.
The regulation process is only active at idle speed, with a warm engine and on condition that the engine speed
is sufficiently stable. An injection timing correction coefficient is assigned to each cylinder; this is "learning" all
the time the regulation process is active and remains fixed at the last value that was learned when the regula-
tion is inactive.
At each new cycle, the coefficients are initialised to 1.
Cylinder Balancing Control
This controller allows smooth behavior of running engine, reduction of noise and oscillations in the drivetrain
by compensating for system dispersions (fuel injectors, compression ratio, manufacturing tolerances of cylin-
ders or valves...) having an influence on the torque generated by each cylinder during combustion.
The controller is only activated if engine is in idle, warm and not too rough. Corrective coefficient on the injec-
tion time is associated with each cylinder that is learnt as soon as the regulation is active. Otherwise it remains
with its last memorized value.
At each new driving cycle, coefficients are initialized to 1.
