Check engine light on? Don’t panic. Express Oil Change & Tire Engineers offers quick and professional car diagnostic services to identify the issue and keep you safely on the road. Our certified technicians use advanced diagnostic tools to read trouble codes, inspect related systems, and provide clear answers - so you know what’s wrong and how to fix it.
No appointment needed. Just walk in!
A diagnostic service uses your vehicle’s onboard computer system to identify problems that trigger warning lights like the check engine light. Our technicians connect a scanner to read error codes, then inspect the related components such as the battery, transmission, cooling system. This process pinpoints the cause of the problem and helps determine the right repair solution.
First, don’t panic. If it’s flashing, that usually means a more urgent problem, so pull over safely. If it’s steady, check your other dashboard warning lights for oil pressure, temperature, or battery alerts. Try tightening your gas cap - one of the most common and easily fixed reasons a check engine light turns on. If the light stays on, bring your car in promptly for a diagnostic test before a small issue becomes a costly repair.
Diagnostics are important because modern cars rely heavily on electronic sensors and systems. Ignoring a warning light can lead to serious damage and expensive repairs. A professional diagnostic test provides a clear explanation of the issue, rules out guesswork, and make sure that only the necessary repairs are made. It saves you money, prevents breakdowns, and keeps your car safe to drive.
You don’t need a diagnostic on a set schedule - it’s triggered by symptoms or warning lights. Common times to get a diagnostic include when the check engine light comes on, when your car struggles to start, when you notice reduced performance, or when unusual noises or smells appear. Many drivers also choose to get a diagnostic check before long trips for added peace of mind.
Your check engine light can turn on for a variety of issues, including:
Loose or faulty gas cap - A simple fix that often resolves the problem.
Battery or charging system issues - Weak batteries or alternators often trigger alerts.
Transmission faults - Trouble codes may indicate slipping gears or sensor failures.
Cooling system problems - Overheating or sensor errors can set off a warning.
Exhaust system or emissions failures - Problems with oxygen sensors or catalytic converters are common culprits.
