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, 1749, 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 selfdiagnosis connector (R10) through the pin 10 for Kline 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.
