IGNITION COIL (Continued)

Fig. 10 IGNITION COIL LOCATION - 2.4L TURBO

High tension leads route to each cylinder from the

coil. The coil fires two spark plugs every power

stroke. One plug is the cylinder under compression,

the other cylinder fires on the exhaust stroke. Coil

number one fires cylinders 1 and 4. Coil number two

fires cylinders 2 and 3. The PCM determines which

of the coils to charge and fire at the correct time.

The Auto Shutdown (ASD) relay provides battery

voltage to the ignition coil. The PCM provides a

ground contact (circuit) for energizing the coil. When

the PCM breaks the contact, the energy in the coil

primary transfers to the secondary causing the

spark. The PCM will de-energize the ASD relay if it

does not receive the crankshaft position sensor and

camshaft position sensor inputs.
