CYCLE PARTS
1 RPM SENSOR
induction sensor
It consists of a 36-tooth phonic wheel
The sensor outputs a voltage pulse every 10° of rotation to
allow the control unit to calculate engine rpm and crankshaft
position
Coil resistance 0.7 – 1.1 KΩ (measured across pins 1a and
1b)
Alternated current at output 1 – 2 V (measured across pins
1a and 1b)
2 LAMBDA SENSOR
oxygen sensor with heater
sensor tension between 0 and 0.9 V (measured across pins
3 and 4)
heater resistance between 12.8 and 14.2 Ω (measured
across pins 1 and 2 at 20°C – 68°F)
Power voltage 12 V.
3 CAMSHAFT SENSOR
Hall sensor
Fitted in the front cylinder head.
The sensor allows the control unit to recognise the precise
sequence of each cylinder by resetting the inner counter
during the ignition asynchronous stage.
12V power across pins 3c and 3a.
Square wave output with a pulse every two rpm (measured
across pins 3b and 3a)
4 COOLANT TEMPERATURE SENSOR
NTC sensor (variable resistance, the value decreases as
the temperature increases)
