2009 CHERY TIGGO ignition

Downloaded from www.Manualslib.com manuals search engine GENERAL INFORMATION
Description
The electronic ignition system consists of the following components:
•Engine Control Module (ECM)
• Ignition Coil
• Spark Plugs
• Spark Plug Wires
• Camshaft Position (CMP) Sensor
• Crankshaft Position (CKP) Sensor
Operation
The ignition system utilizes a split ignition coil which supplies secondary voltage to two cylinders. When the ignition
coil discharges, two spark plugs fire at the same time. The Engine Control Module (ECM) uses inputs from the
Crankshaft Position (CKP) Sensor to determine the Top Dead Center (TDC) position of the piston for cylinder number
one, and the Camshaft Position (CMP) Sensor to determine which ignition coil to energize.

Ignition Coil 1.6L & 1.8L & 2.0L
Description
The ignition coil consists of primary and secondary groups of wire. The primary wire is located on one end of the coil.
One end of the wire is connected to power and the other end is connected to the Engine Control Module (ECM). The
secondary coil connects two spark plugs. They form a loop and provide high-voltage output.
Operation
When the primary wire is connected to power, current will flow causing a strong magnetic field to form. When the
primary wire is disconnected, the magnetic field will collapse into the secondary wire causing very high voltage out-
put.
Removal & Installation
1. Remove the engine cover.
2. Disconnect the negative battery cable.
3. Disconnect the ignition coil electrical connector.
4. Twist the spark plug wires (1) from the ignition coiland remove the four spark plug wires.
