Ignition Capacitor

WARNING: This page is about a different variant/trim than selected.
IGNITION CAPACITOR

Refer to COMPONENT INDEX .

The coil capacitor helps dampen the amount of conducted electrical noise to the CMP, CKP, and Throttle Position Sensor (TPS). This noise is generated on the 12v supply wire to the ignition coils and fuel injectors. The ignition capacitor also provides a voltage to the ignition coil allowing for less ramp time when the coil is activated.
