If you don’t replace the gas cap after refueling, your check engine light may illuminate. Be sure to check that the cap is tightened correctly, then continue driving for a few miles to allow the sensors to reset. If the light stays on, there is likely another issue going on.
Replacing a lost gas cap is easy! Stop by a local auto parts store to find a suitable lid for your specific vehicle.
The spark plugs ignite the fuel and air mixture in the engine to start combustion and power the vehicle. These tiny components have a big job to do and are very susceptible to wear over the lifespan of your car. They’ll likely need to be swapped out to prevent engine misfire.
Worn coils and spark plugs exhibit similar warning signs of failure. Replace both to confidently rule them out as a cause of the check engine light. You could save yourself the trouble of replacing one or the other shortly after.
Oxygen sensors measure the amount of unburned oxygen in the exhaust system. They send data to a computer that controls the amount of air that enters the fuel for maximum efficiency. Like spark plugs, these tiny parts are easily susceptible to failure over time after years of use. They could be the trigger for your check engine light.
A car with faulty oxygen sensors can still operate, but you may be burning more fuel than usual.
Is one of these parts the reason for your vehicle’s check engine light? These are simple fixes that the team at Motorcars International in Smyrna, Georgia can easily perform. It’s best to visit our experts for final diagnosis to ensure something more serious isn’t going on under the hood.
