Check Engine Light On? Common Causes & What to Do
Today’s vehicles are manufactured with complex interrelated systems. On-board computers continuously monitor and store information concerning the performance of these systems.
A warning light comes on because the computer has sensed a signal from one of the systems or components that has gone outside of its normal operating range. The computer then sends a signal to turn on the dashboard light to let you know something is wrong!
How can Kwik Kar “diagnose” my problem?
At Kwik Kar, we have the tools, training, and technology to handle diagnostic issues, from Check Engine lights to ABS Warning lights. Our complete diagnostic process includes:
1. Retrieve Data – Using advanced scan tools, we analyze your car’s onboard computer to gather codes, freeze frame data, software versions, and sensor info. Simply pulling codes isn’t enough for an accurate diagnosis.
2. Verification Testing – We verify that systems like engine vacuum, timing, ignition, fuel, and emissions meet specifications to avoid misdiagnosis.
3. Pinpoint Testing – We conduct detailed testing, including electrical and mechanical tests, wiring checks, and bi-directional control tests to identify the exact problem.
4. Research Technical Service Bulletins (TSBs) – We consult TSBs to check for any known issues with your vehicle type but still perform thorough testing to confirm.
5. Car Repair – Repairs may involve parts replacement, cleaning, software updates, or wiring repairs.
6. Verify Repair – After repairs, we retest your vehicle to ensure the issue is fully resolved and functioning correctly.
Check Engine Diagnostic FAQs
How long will it take to diagnose my problem?
In most cases, Kwik Kar can diagnose and fix the issue on the same day, getting you back on the road quickly.
Do I need an appointment?
Appointments aren’t usually required at most Kwik Kar locations, but it’s always a good idea to call ahead to check availability. We aim to provide service times that are convenient for you.
How much will it cost?
Diagnostic fees vary by location and are typically charged at an hourly or procedural rate. Contact your nearest Kwik Kar using our store locator for a detailed estimate. Check Engine Light diagnostics are often a fixed rate unless further testing is needed.
Why does my parts store offer a free Check Engine light diagnostic?
Parts stores offer basic code reading for free, but they don’t perform the complete diagnostic procedures needed to pinpoint the exact issue. Kwik Kar’s certified technicians use advanced tools and expertise to accurately diagnose and fix your vehicle.
What are examples of vehicle operating issues that require diagnostics?
Common issues requiring diagnostics include dashboard warning lights (Check Engine, ABS), emissions failures, engine or transmission performance problems, and steering or ride control issues. Kwik Kar uses high-quality parts that meet or exceed manufacturer standards, and we’ll return your old parts if you’d like! If a warning light comes on, trust our experts to handle it.
