Common Check Engine Light Triggers
The check engine light (CEL) can be triggered by various issues in your vehicle's engine or emissions system. While the specific triggers can vary depending on the make and model of your car, here are some common check engine light triggers and suggestions on what to do about them:
- Loose or damaged gas cap: A loose, damaged, or missing gas cap can cause the check engine light to come on. Check the gas cap to ensure it is tightened properly. If it is damaged, replace it with a new one. In most cases, the light will go off after a few driving cycles once the cap is secure.
- Oxygen sensor malfunction: The oxygen sensor monitors the oxygen levels in the exhaust system. A faulty sensor can lead to poor fuel economy and increased emissions. It is advisable to have a professional diagnose and replace the faulty sensor.
- Catalytic converter issues: The catalytic converter reduces harmful emissions from the exhaust. Problems with the catalytic converter can trigger the check engine light. Diagnosing and repairing catalytic converter issues typically require professional assistance.
- Mass airflow sensor (MAF) failure: The MAF sensor measures the amount of air entering the engine. A malfunctioning sensor can cause poor performance and reduced fuel efficiency. Cleaning or replacing the MAF sensor may be necessary.
- Spark plug or ignition coil problems: Worn-out spark plugs or faulty ignition coils can result in engine misfires. These can trigger the check engine light. Inspect and replace spark plugs or ignition coils as needed.
- EGR valve malfunction: The exhaust gas recirculation (EGR) valve directs some exhaust gases back into the combustion chamber to reduce emissions. If the EGR valve is stuck open or closed, it can cause engine performance issues. Professional assistance is recommended to diagnose and repair EGR valve problems.
- Malfunctioning thermostat: A faulty thermostat can cause the engine to overheat or operate at an incorrect temperature. This can trigger the check engine light. Have a professional inspect and replace the thermostat if necessary.
- Faulty or loose sensors: Various sensors in your vehicle, such as the crankshaft position sensor or camshaft position sensor, can malfunction or become loose, leading to the check engine light coming on. Professional diagnosis and repair are typically required.
In any case, when the check engine light comes on, it is recommended to have your vehicle inspected by a qualified mechanic or automotive service technician. At the Berglund Mazda service center in Salem, we use diagnostic tools to retrieve error codes from the vehicle's onboard computer system, which will help identify the specific problem. Avoid ignoring the check engine light for an extended period, as it may indicate a significant issue that requires attention to prevent further damage to your vehicle.
Other Common Warning Lights
Oil Light
It's important to pay attention to the oil light on your car's dashboard. If it comes on, pull over and check the oil levels with a dipstick. If it's low, add more oil. If it's dirty or you suspect a leak, make an appointment with a service center.
Tire Pressure Warning Light
The tire pressure warning light can indicate low or high pressure, not just a flat tire. If it flashes at start-up, there may be a problem with the monitoring system. Check the pressure and adjust it as needed. If the light stays on, schedule a service appointment with Berglund Mazda.
Engine Temperature Warning Light
If your engine temperature warning light comes on, turn off the engine and contact roadside assistance immediately. But don't panic; your engine may be overheating for something as minor as low coolant levels; however, delaying action could result in significant damage.
Battery Warning Light
If you see a rectangular symbol with a plus and minus sign, it's the battery warning light. Check for loose cables or corrosion on the battery. If that doesn't work, see a professional to test your battery, starter, and alternator.
