Why is my transistor failing?
The common cause of one driver/transistor failing is a shorted ignition coil primary winding. This is a winding of wire within the ignition coil where each loop is separated by a very thin plastic coating.
What is waste spark ignition?
Each ignition coil makes a spark for two companion cylinders in what's called a waste spark ignition system. Each time one of the coils fires, two spark plugs receive a spark. One cylinder is on its compression stroke and the other is on its exhaust stroke.
What happens if the ignition module fails?
If the ignition module has failed completely, the vehicle won’t get spark and won’t start. Continuing to drive with the symptoms mentioned above can damage your car’s catalytic converter. If you notice these symptoms, get your car checked out right away.
What is the role of the ignition control module?
Up until around the turn of the century, that task belonged to the ignition control module. The ignition module is responsible for firing the spark plugs. Each spark plug must fire at exactly the right time for the engine to run properly.
What is the difference between ECM and ignition module?
On some vehicles, the ECM may control ignition timing above a certain engine RPM, while the ignition module has control below a certain RPM. In these instances, the signal from the sensor may first be sent to the ignition module.
What causes a check engine light to turn on?
A faulty ignition control module can cause a number of problems. 1. Check engine light is on: The ECM monitors all parts of the vehicle that could affect emissions. This includes the ignition system. If it determines the ignition module has caused a problem with the system, it will turn on the check engine light. 2.
