Ignition control module is an essential component of a vehicle’s ignition system. It is responsible for controlling the timing and duration of the spark that ignites the air-fuel mixture in the engine’s cylinders. A faulty ignition control module can cause a variety of problems, including engine misfires, rough idling, and poor fuel economy.
There are a few simple steps that you can take to check your ignition control module. First, locate the module. It is usually mounted on the firewall or near the distributor. Once you have located the module, disconnect the electrical connectors. Next, use a multimeter to test the resistance between the terminals on the module. The resistance should be within the specifications listed in your vehicle’s service manual. If the resistance is not within specifications, the module is likely faulty and should be replaced.
