Ignition system device 1 - speed and crankshaft position sensor; 2 - ECU of the fuel injection system; 3 - block of ignition coils; 4 - camshaft position sensor.
Ignition coils (TU5 petrol engine) The compact ignition coil pack consists of two ignition coils with two high voltage outputs each. The block is installed directly above the spark plugs. The dual ignition coil has two independent primary and two...
Speed and crankshaft position sensor (TU5 petrol engine) The crankshaft speed and position sensor faces the marks on the flywheel. It consists of a magnetic core surrounded by a winding. When the flywheel teeth pass the sensor, a change in the magnetic field is created in it,...
Speed and crankshaft position sensor (EP series gasoline engines) The crankshaft speed and position sensor faces the marks on the flywheel. It consists of a magnetic core surrounded by a winding. When the flywheel teeth pass the sensor, a change in the magnetic field is created in it,...
Knock Sensor (EP Series Gasoline Engines) The knock sensor has a built-in piezoelectric potentiometer. Engine knock information from the sensor allows the engine ECU to correct the ignition timing. The signal is due to the detonation of the air-fuel mixture in...
Camshaft Position Sensors (EP Series Gasoline Engines) The sensors are «hall sensors». Information about the position of the camshafts comes from sensors in the engine ECU in the form of rectangular signals. Based on this information, the engine ECU: synchronizes fuel...
Spark plug Note. The use of worn spark plugs leads to increased fuel consumption and increased levels of toxic emissions in the form of exhaust gases. Correct spark plugs The color of the end face of the insulator near the trawl...
Replacing the crankshaft sensor (petrol engine) Remove the protective shield under the engine. Unclip the wiring harness (in the zone «b»). Remove the pin (in the zone «A») and protective case (1). Loosen the hex head screw (3) crankshaft sensor (2) and take it off....
Replacing the crankshaft sensor (diesel engines) Disconnect the battery. Raise the vehicle and secure it so that the wheels are off the floor. Remove the following parts: protection under the engine; front right wheel; front liner; accessory drive belt. Install the...
Replacing the knock sensor (petrol engines) Disconnect the battery. Remove the protective shield under the engine. Disconnect and move aside the canister solenoid valve (2) (in the zone «b»). Disconnect the sensor connector in the area «A»). Remove the bolt (3)...
Replacing the camshaft position sensor (petrol engines) Disconnect the battery. Remove the following parts: air deflector (4); air resonator (5); bolt (2); air intake connector (3). Disconnect the camshaft position sensor electrical connector (in the zone «A»). Release the...
Replacing the Camshaft Position Sensor (Diesel Engines) Disconnect the battery. Release and move the damper actuator (forward). Disconnect the connector in the area «A». Remove the bolt (1) and remove the camshaft position sensor (2). Installing a Reusable Sensor Install the...
Removing coils and spark plugs Note. When exposed to the ignition coil retainer (1) the electrical connector of the harness is disconnected. Press the ignition coil lock (1) (in the zone «A») (as shown by the arrow). Disconnect harness electrical...
General information about the preheating system The operating time of the preheating and afterheating is determined by the engine ECU depending on the temperature! engine coolant temperature! air, atmospheric pressure, as well as the used phase of the engine (e.g....
Replacing glow plugs (1.6L engine) Remove the damper actuator and decorative battery cover. Disconnect the positive and negative battery terminals. Remove the air filter assembly (see corresponding operation). Note. Use a mirror to perform the operations...
