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 coil
and remove the four spark plug wires.
