Fuel System/Engine Management
Idle fueling
Adjustment of fueling at idle to suit the actual air inducted.
Idle reference speed
The target idle speed as determined by the Electronic
Control Module <ECM>. (lt should be the same as the
actual idle speed if the motorcycle is operating correctly.>
Ignition advance
The timing of the ignition at the spark plug relative to top
dead centre <TDO.
Ignition switch position
The 'ON' or 'OFF' position of either or both the ignition
switch and the engine stop switch.
Ignition timing
Same as 'ignition advance'.
Immobiliser and Tyre Pressure Monitoring
System <TPMS> Control Module
The control module for the Immobiliser and TPMS
system.
lniector pulse time
The time during which an injector remains open (i.e.
delivering fuel>.
Lambda
02
Sensor
The Lambda sensor measures the Oxygen levels in the
exhaust gases and feeds this information to the ECM.
Based on this information, adjustments to air/fuel ratio are
made.
Long term fuel trim
Fueling after adapting to the engine's long term fueling
requirements <closed loop only). See also short term fuel
trim.
MAP sensor
Manifold Absolute Pressure (the air pressure in the intake
system). Measured after the throttle valves. This reading is
compared to the ambient pressure reading to allow the
ECM to calculate engine load.
MIL
Malfunction Indicator Lamp.
Illuminates when most Diagnostic Trouble Codes <DTCs)
are set.
Open circuit
A break in an electrical circuit - current cannot flow.
Over temp
High temperature within the Electronic Control Module
<ECM> caused by an internal or external failure.
Primary throttle position sensor
Sensor for the primary <lower) throttle position.
Primary throttle stepper motor
Stepper motor used to vary throttle opening at idle and
when the engine is cold.
Purge valve duty cycle
The time the purge valve is open in an open/close cycle,
expressed as a percentage of the cycle time.
Road speed sensor
Gearbox mounted sensor which delivers information to
the ECM. This is converted to the road speed value that is
then displayed on the speedometer.
Non ABS models only. ABS models use the rear ABS
wheel speed sensor to supply road speed sensor to the
ECM.
Sensor supply voltage
Supply voltage to the system sensors <nominally 5 Volts>.
