ENGINE 1.3L QUADRAJET (90PS)
101
The latter receives power and earth signals from pins
15 and 32 of connector V of ECU and sends a signal
to pin 41.
Water in fuel & fuel temperature Sensor (K101)
The water in fuel & fuel temperature sensor is
powered from fuse 20A. Earth to the sensor is from
pin 1, 2, 3 of connector V of ECU, It receives a
reference earth for fuel temperature sensor from pin
13 of connector V of ECU and sends a fuel
temperature signal to pin 61.
Turbo Pressure & temperature Sensor (K82)
This sensor is not available in 75ps version &
available in 90ps version
The Turbo pressure & temperature sensor K82
measures the pressure and the temperature in the
intake chamber, downstream of the turbocharger. It
is supplied by pin 23 of Connector M of ECU and
receives a reference earth from pin 24 of Connector
M. A signal corresponding to the pressure level is
sent to pin 41 of Connector M of ECU, the signal
corresponding to the temperature is sent to pin 37 of
Connector M.
Rail Pressure Sensor (K83)
Fuel pressure sensor K83 supplies the ECU with a
feedback signal to modulate injection pressure and
duration.
It receives power and a reference earth from pins 8
and 6 of Connector M of ECU; it then sends a
pressure signal to pin 38.
Lambda Sensor (K40)
This sensor is not available in BSIII application &
available in E-4 version
Lambda sensor K40 sends signals to pins 44, 45
and 47 of connector V of ECU while pin 46 supplies
a reference earth. Sensor K40 is heated by a coil to
ensure efficient operation even when cold. The coil
is supplied by the line of fuse 15A and receives an
earth signal from pin 12 of connector V of control
unit ECU.
Rail Pressure Regulator (DRV) (N17)
The fuel pressure regulator on the pump N17 controls
the high pressure produced by the actual pump; the
two control signals come from pins 4 and 34 of
Connector M of control unit ECU.
Solenoid EGR Valve (EVRV) (L30)
The EGR solenoid valve (EVRV) L30 is supplied by
a line from fuse 15A which goes to pin 5 of connector
M of ECU as well and is controlled by a signal from
pin 15 of Connector M of ECU
Injector (N70)
The engine management control unit sends the
command to the injectors N70 from pins 16-47, 17-
49, 31-48, 1-46 of Connector M of ECU for cylinders
1, 2, 3 and 4, respectively.
Brake Switch (I30)
Pin 92 of connector V of Engine control unit receives
a signal from brake light switch (I30) - NO contact –
which is provided with an ignition-controlled power
supply from fuse (10A).
Pin 68 of connector V receives a signal – from NC
contact – of brake light switch (I30), which is supplied
with an ignition controlled supply from fuse (10A).
Clutch Switch (I31)
Pin 90 of connector V of Engine control unit receives
the signal from the clutch switch (I31).
Vehicle Speed Signal for EMS :
The Engine Control unit receives this signal through
pin 93 of vehicle connector, from the instrument
cluster.
System self-diagnosis (Kline) connector (D29) :
The Engine Control unit is connected to System self-
diagnosis connector (R10) through the pin 10 for K-
line diagnosis.
Instrument Cluster (E50)
The Engine Control unit drives the following in
instrument cluster
Max water temperature lamp through the pin 75 of
connector V of ECU
Engine RPM Signal through pin 29 of connector V of
ECU.
Glow Plug Heater Lamp through pin 52 of connector
V of ECU.
Self Diagnostic Lamp (service) through pin 77 of
connector V.
EOBD lamp (MIL) through the pin 78 of connector V
of ECU.
