Understanding 4 Common Check Engine Light Problems
Seeing the check engine light illuminate on your dashboard can be stressful for any driver. While the light doesn’t always signal an immediate emergency, it does mean your vehicle’s onboard computer has detected a problem that needs attention. Ignoring the warning can lead to reduced performance, poor fuel-economy, or costlier repairs down the road. Understanding some of the most common causes behind a check engine light can help you respond quickly and make informed decisions. At Mata Auto Repair, we provide expert check engine light diagnostics and repair in the greater Omaha area. Here are four frequent check engine light problems drivers encounter.
Failing Oxygen Sensor
Oxygen sensors monitor the amount of unburned oxygen in the exhaust and help the engine adjust the air-fuel mixture. When an oxygen sensor fails, the engine may run too rich, reducing fuel-efficiency and increasing emissions. Over time, a bad oxygen sensor can also damage the catalytic converter. Replacing a faulty sensor helps restore proper engine performance and fuel-economy.
Malfunctioning Catalytic Converter
The catalytic converter plays a critical role in reducing harmful exhaust emissions. When it begins to fail, you may notice poor acceleration, reduced power, or a sulfur-like smell. A malfunctioning catalytic converter often triggers the check engine light. Addressing related issues early, such as sensor failures, can help prevent converter damage.
Ignition System Problems
Worn spark plugs, damaged ignition coils, or faulty wiring can cause engine misfires that trigger the check engine light. Misfires may lead to rough idling, hesitation, or reduced power. Regular maintenance helps reduce the risk of these problems.
Faulty Mass Air Flow Sensor
The mass air flow (MAF) sensor measures how much air enters the engine so the computer can calculate the correct amount of fuel. When the MAF sensor fails, the engine may stall, idle roughly, or experience poor acceleration. This issue often results in decreased fuel-efficiency and increased emissions. Replacing the sensor can restore proper engine operation.
