Sensor of
Dump
Voltage of 2 V DC
when the vehicle is
inclined ECU cuts the current to
main relay and ignition
4
Side Stop
Switch
Voltage of 5 CC in case
the vehicle parks on the
side panel
ECU will turn on the side panel
indicator on the board and cut off the
power to the ignition system.
5 Se
oxygwn
sensor
The voltage signal will depend on
the amount of oxygen in the
exhaust. ECU determines the fuel-air
mixture and regulates it if
necessary.
6 S 6 S
sensor of the
Crankshaf
t Angle
Sens the turn of the crankshaft
and gives the entry pulse to the
ECU
ECU calculates the number of
pulses per revolution and indicates
the engine RPM in the tachometer
of the board. It gives an input
signal to the ECU for the ignition
circuit.
7 Se 7 Se
sensor
Throttle
Position
Monitors the throttle position
and gives a voltage input to the
ECU according to the partial or
total acceleration mode.
ECU increases or reduces the
rate of fuel injected to the
engine.
MAP
sensor
8 T
Monitors the temperature and
pressure of air entering the
intake manifold and delivers a
signal to the ECU 5 VDC.
ECU increases or decreases the rate
of air to the engine proper
Effect if abnormality
1. The radiator fan will not operate and the
temperature can be triggered affecting engine
performance.
2. The icon of high coolant temperature
may not light.
3. Start, fuel consumption and output may be
affected.
Driving the vehicle with low oil level may result
in premature engine parts damage. The engine
will continue to operate in case of accident or
slip of the vehicle and can result in serious injury
to the driver and vehicle damage.
There will be no indication that the board is on the
side hostel. The vehicle will not start if you are in
any way.
The malfunction of the oxygen sensor can result
in a rich mixture is evidenced by a black exhaust
smoke or lean impacting vehicle operation. Error
in indication of engine speed on the board.
Improper operation of the ignition
system.Do not start if open circuit.
