When the check engine light appears on your dashboard, it’s easy to ignore—especially if the car still seems to run fine. But that warning light is your vehicle’s way of telling you something is wrong, and ignoring it can lead to more expensive repairs or even breakdowns. Many issues triggered by the check engine light require prompt attention to protect your engine and ensure your vehicle remains reliable. At Powerhouse Auto Repair, we provide expert check engine light diagnostics and repair in the greater Tallahassee area. Here are four common check engine light problems that should be addressed as soon as possible.

Faulty Oxygen Sensor

The oxygen sensor monitors how much unburned oxygen is in your car’s exhaust. A failing oxygen sensor can cause the engine to run too rich or too lean, reducing fuel-economy and increasing emissions. If left unaddressed, it can damage the catalytic converter over time, leading to a more costly repair. Replacing a bad oxygen sensor is relatively quick and inexpensive compared to the damage it can prevent.

Catalytic Converter Failure

The catalytic converter plays a vital role in reducing harmful emissions from your exhaust system. If it starts to fail, your car may run poorly and emit a sulfur-like smell. Because it’s a major component of the emissions system, prompt replacement is crucial to maintaining your vehicle’s efficiency and preventing excessive pollution.

Malfunctioning Mass Airflow Sensor

The mass airflow sensor helps your engine determine how much fuel to inject based on the amount of air entering the system. If the sensor goes bad, it can cause rough idling, stalling, poor fuel-economy, and hesitation during acceleration. Replacing a faulty MAF sensor can help restore optimal engine performance.

Ignition System Issues

Problems with spark plugs, ignition coils, or related components can also trigger the check engine light. If your car misfires, stalls, or accelerates unevenly, it could be due to a faulty ignition system. Prompt repair helps ensure smooth engine operation.
