When something is wrong with one of your vehicle’s parts, it can be hard to tell right off the bat. Luckily, our vehicles come equipped with a system of warning lights that alert us when something is wrong. Through our dashboard lights, our vehicle will show us which area of the car needs to be looked at. Whether you’re looking for info for your [primary make], [secondary make], or another manufacturer, these dashboard lights have mostly universal appearances.
However, sometimes it is not very obvious what this light is trying to tell us. One dashboard light that turns on when various parts are malfunctioning is the Check Engine light. If your Check Engine light turns on, it is a good idea to observe when the light turns on and if the light is flashing or steady. Generally speaking, a steady Check Engine light does not mean the issue is immediately urgent (although you should still get the issue checked out), but if the light is flashing, you should get your car checked at an auto repair shop immediately. If you are in Briar Forest, TX, Houston, TX, Memorial, TX, Meadows Place, TX, Bellaire, TX, or nearby, you can come to McDaniel Auto Care in Harris County. We can determine why your Check Engine light has turned on by performing a Check Engine light diagnostic and fix the issue efficiently and skillfully.
- Oxygen Sensor Failure: Your O2 sensor monitors the amount of unburnt oxygen in the exhaust. While your car will stay running if this sensor fails, you’ll experience a significant drop in fuel efficiency and potentially damage your catalytic converter over time.
- Loose or Damaged Gas Cap: This is one of the most common (and simplest) fixes. If the light appears shortly after a trip to the gas station, your fuel cap may be loose, cracked, or missing, causing a leak in the evaporative emissions system.
- Catalytic Converter Issues: This component converts harmful carbon monoxide into carbon dioxide. While these are designed to last, failure is often caused by neglecting other maintenance—like regular oil changes or ignoring a faulty spark plug.
- Ignition Coil & Spark Plug Malfunction: Ignition coils provide the electricity needed for spark plugs to ignite the fuel-air mixture. If these components fail, your engine will misfire, resulting in poor performance and reduced gas mileage. (Note: Diesel engines do not use this system).
- Worn Spark Plug Wires: Over time, these wires can corrode or crack. Signs of failure include a rough idle, a noticeable drop in engine power, and a glowing Check Engine light. Replacing these promptly prevents more expensive engine damage.
- Mass Airflow (MAF) Sensor Failure: The MAF sensor calculates how much air is entering the engine to ensure the proper fuel mix. If your car is idling roughly, stalling, or having trouble starting, this sensor is a likely culprit.
On-Board Diagnostics, or OBD, is a computer system in your vehicle’s diagnostic system established in 1996 that monitors and identifies issues with your vehicle. When the OBD system identifies an issue, it turns on the Check Engine light and records an OBD trouble code. When you bring your vehicle to McDaniel Auto Care, we pull codes from the OBD system by plugging a code reader, or scan tool, into your vehicle’s OBD port. These codes provide us with more information about the conditions the Check Engine light was under when it turned on, making it easier for us to identify what the issue is with your vehicle.
