What is coil over plug?
In this regard, how does coil over plug work?
With the Coil On Plug Ignition System, each spark plug is ignited by its own coil. That means the (PCM) or (ECM) can control the spark and spark timing on an individual, per-cylinder basis. That gives better control over spark timing for more horsepower, better mileage and fewer emissions.
Also Know, how long do coil over plugs last? Federal law in the United States dictates that the ignition coil and ignition module on new vehicles are warranted for at least two years or 24,000 miles, whichever occurs first. The insulation in the ignition coil will degrade over time, but many coils are designed to last 100,000 miles or more.
Regarding this, is coil on plug better?
Coil on plug has several advantages over conventional distributor type systems: 1) Less voltage loss from the coil to the plug. With fewer connections and the elimination of the distributor rotor to cap air gap. 2) Can be used in conjunction with injector control to have the ECM perform misfire diagnosis.
How do you test a coil pack?
Test the coil with a multimeter. Disconnect the coil pack's electrical connector then remove the coil pack from your car's engine using a wrench. Set the ohmmeter/multimeter to 200 ohms range then turn it on. Using a meter lead, attach the spark plug wire terminal to each coil.
