Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
