Common reasons for the check engine light to come on

The check engine light in a Triumph can come on for a variety of reasons. It is important to understand these common reasons in order to effectively diagnose and address the issue. One common reason for the check engine light to come on is a loose or faulty gas cap. If the gas cap is not properly tightened, it can cause the check engine light to illuminate. Another common reason is a malfunctioning oxygen sensor. The oxygen sensor measures the amount of oxygen in the exhaust and helps regulate the fuel-to-air ratio. If the sensor is faulty, it can cause the check engine light to come on. Additionally, a misfiring engine or a problem with the catalytic converter can also trigger the check engine light. It is important to address these issues promptly to prevent further damage to the vehicle.
