DIAGNOSIS AND TESTING
Monitors
The purpose of the monitors is to continuously
check the operation of the emission related sensors
and actuators. It then establishes if they are
operating within specified tolerances. All monitors
carry out their functions in such a way as to be
unnoticeable by the driver of the vehicle. Each one
is carried out under specific conditions of load,
speed and engine temperature. The Comprehensive Component Monitor, Combustion
Misfire Monitor and
AirIFuel Ratio Monitor operate
continuously. The remaining monitors are only
invoked under certain operating conditions. On
diesel variants, all of the monitors operate under
normal driving conditions: There are no monitors
which intervene and cause special operating
modes to enable the monitors to work. Some diesel
monitors are non-continuous. This means that in
a drive cycle, monitoring is done as and when
suitable driving conditions exist and potential faults
are accumulated and compared with acceptance
criteria. Examples of this type are the turbocharger
boost pressure and exhaust gas recirculation
(EGR) monitors on vehicles with common rail fuel
injection.
( Comprehensive Component Monitor (CCM)
When the CCM detects a component operating out
of tolerance, it sets a Diagnostic Trouble Code
(DTC), which is stored in the EEPROM. If the same
concern is confirmed during the next trip the MIL
will be switched on. The CCM monitors many
components, sub-systems and signals. The
following is a list of those that can effect emissions
depending on application:
Electronic Ignition (El) System.
Crankshaft Position (CKP) Sensor.
Ignition Coil.
Electronic Throttle Control Unit.
Camshaft Position (CMP) Sensor.
Air Conditioning
(AIC) Clutch.
Idle Air Control (IAC) Valve.
Mass Air Flow (MAF) Sensor.
Manifold Absolute Pressure (MAP) Sensor.
Intake Air Temperature (IAT) Sensor.
Engine Coolant Temperature (ECT) Sensor.
Cylinder Head Temperature (CHT) Sensor.
Heated Oxygen Sensor
(H02S).
Catalyst Monitor Sensor.
Charge Air Temperature Sensor.
Knock Sensor (KS).
Throttle Position (TP) Sensor.
Vehicle Speed Sensor (VSS).
Boost Pressure Sensor.
Cam-Crank Phasing Sensor.
EEPROM.
High Pressure Fuel Injection Pump.
Exhaust Gas Recirculation (EGR) Valve Monitor.
Fuel Injectors.
Turbocharger.
Combustion Noise Monitor.
Barometric Pressure (BARO) Sensor.
Combustion Misfire Monitor (All except vehicles
with diesel engine)
The combustion misfire monitor operates independently of the others, and can detect misfires
caused by the ignition system, fuel system or
mechanical engine components. As each cylinder
fires, a characteristic crankshaft acceleration is
produced. The monitor detects irregularities in the
acceleration pattern using the crankshaft position (CKP) sensor, thus detecting the misfire. It can
also detect which cylinder has misfired.
Combustion misfires can be categorized as follows:
Type
A: These can cause catalytic converter
damage due to excessive internal temperatures.
If a certain number of misfires occur over a
pre-determined number of engine revolutions, the
MIL will be switched on to alert the driver of the
concern.
Type B: These can lead to an increase in emissions
to a point above the EOBD threshold. If the misfire
is detected during a second trip, over a,
pre-determined number of engine revolutions, the
MIL will be switched on. If the misfire does not
occur over the next three trips, the MIL will be
extinguished
AirIFuel Ratio (AFR) Monitor (All except vehicles
with diesel engine)
The H02S fitted before the catalytic converter
(upstream) measures the oxygen content of the
exhaust gas and the variations in it. This then
enables the PCM to adjust the opening times of
the fuel injectors to maintain the correct AFR. This
is known as Short Term Fuel Trim (STFT). If the
same variation is registered a pre-determined
number of times, a permanent correction factor is
applied. This is known as Long Term Fuel Trim
(LTFT), which is stored in the EEPROM. When the
correction factors exceed pre-determined limits a
DTC will be set in the EEPROM. If a concern is
