Description And Operation

DESCRIPTION 

GC0195216Courtesy of CHRYSLER GROUP, LLC

One coil capacitor (1) is used. It is located in the right section of the engine compartment.

OPERATION 

The coil capacitor helps dampen the amount of conducted electrical noise to the camshaft position sensor, crankshaft position sensor, and throttle position sensor. 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.
