Vehicle ignition system Peugeot 207

General information about the ignition system of the TU5 petrol engine
Gasoline engines use a duostatic ignition system, in which the ignition coils are made in the form of a single compact unit (there are no high voltage wires), located and secured to the cylinder head.

Ignition system device
1 - crankshaft speed and position sensor; 2 - Fuel injection system ECU; 3 - ignition coil block; 4 - camshaft position sensor.

Ignition coils (TU5 petrol engine)
The compact ignition coil unit consists of two ignition coils with two high voltage outputs each. The unit is mounted directly above the spark plugs. The dual ignition coil has two independent primary and two secondary...

Crankshaft speed and 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,...

Crankshaft speed and 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. Information about engine knock coming from the sensor allows the engine ECU to make ignition timing correction. The signal is generated by detonation of the...

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 control unit in the form of rectangular signals. Based on this information, the engine ECU: synchronizes...

Spark plugs
Note: Using worn spark plugs will result in increased fuel consumption and increased levels of toxic exhaust emissions. Good spark plugs The color of the end of the insulator near the trawling electrode changes from...

Replacing the crankshaft sensor (petrol engine)
Remove the protective shield under the engine. Release the wire harness from the clamps (in area "b"). Remove the pin (in area "a") and the protective cover (1). Loosen the hexagon head screw (3) of the crankshaft...

Replacing the crankshaft sensor (diesel engines)
Disconnect the battery. Raise the vehicle and support it so that the wheels do not touch the floor. Remove the following parts: protection under the engine; front right wheel; front fender liner; drive belt for...

Replacing the knock sensor (petrol engines)
Disconnect the battery. Remove the protective shield under the engine. Disconnect and move aside the solenoid valve of the adsorber (2) (in area "b"). Disconnect the sensor connector in area "a"). Loosen 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 connecting element (3). Disconnect the camshaft position sensor electrical connector (in area "a"). Release...

Replacing the camshaft position sensor (diesel engines)
Disconnect the battery. Release and push the flap actuator (forward). Disconnect the connector in area "a". Loosen the bolt (1) and remove the camshaft position sensor (2). Installing a reusable sensor Install the...

Removal coils and spark plugs
Note: When the ignition coil lock (1) is pressed, the electrical harness connector is disconnected. Press the ignition coil lock (1) (in area "a") (as shown by the arrow). Disconnect the electrical harness connector (in...

General information about the pre-heating system
The operating time of the pre-start and post-heating is determined by the engine ECU depending on the temperature of the engine coolant, the temperature of the air, the atmospheric pressure, and the phase of engine...

Replacing glow plugs (1.6L engine)
Remove the throttle actuator and the decorative battery cover. Disconnect the positive and negative battery terminals. Remove the air filter assembly (see the corresponding operation). Note: Use a mirror to perform the...
