Check Engine Light

The check engine light is perhaps the most well-known, feared and commonly encountered dashboard light. It typically appears as an illuminated engine symbol or the words "check engine." This light can indicate a wide range of issues, ranging from minor to severe. Some common causes include a loose gas cap, a faulty oxygen sensor, or a malfunctioning catalytic converter. When the check engine light illuminates, it's essential to have your vehicle diagnosed by a qualified mechanic to identify and address the underlying problem.

Battery Warning Light

The battery warning light, often depicted as a battery symbol, indicates an issue with your vehicle's charging system. It could signify a faulty alternator, a loose or worn-out drive belt, or a weak battery. If this light illuminates while driving, it's advisable to take immediate action, as a failing charging system can result in a dead battery and a stranded vehicle.

Oil Pressure Warning Light

The oil pressure warning light, typically represented by an oil can or the letters "OIL," alerts you to low oil pressure in your engine. Low oil pressure can be caused by a variety of factors, including insufficient oil levels, a faulty oil pump, or a clogged oil filter. Running the engine with low oil pressure can lead to severe engine damage.

Tire Pressure Monitoring System (TPMS) Light

The TPMS light, usually depicted as an exclamation point inside a tire symbol, indicates an issue with your vehicle's tire pressure. It is designed to alert you when the tire pressure drops below the recommended level, which can compromise handling, fuel efficiency, and tire life. When this light illuminates, check your tire pressure and inflate or repair any underinflated or damaged tires promptly.

Brake System Warning Light

The brake system warning light, often represented by the letters "ABS" or an exclamation point inside a circle, indicates a problem with your vehicle's braking system. It can signify various issues, such as low brake fluid, a malfunctioning ABS (anti-lock braking system), or worn brake pads.
