That check engine light can mean many things—from a loose gas cap to a serious engine problem. At Whetzel’s Automotive, we use advanced engine diagnostic equipment to pinpoint the exact issue, so you only pay for repairs you actually need. No guessing, no unnecessary parts. Serving West Columbia, Columbia, Lexington, Cayce, Irmo, and Forest Acres.
Your check engine light is part of your vehicle’s onboard diagnostic system (OBD-II). When it illuminates, it means the computer has detected a problem that could affect emissions or engine performance. Here’s what the different states mean:
A steady light typically indicates a non-emergency issue—something like a failing sensor, emissions problem, or minor engine issue. You should schedule a service soon to prevent the problem from worsening.
A flashing light is urgent. It usually indicates an engine misfire that could damage your catalytic converter—an expensive repair. Pull over safely and call for assistance. Don’t continue driving.
Intermittent lights often indicate a developing problem. Even if the light goes off, the trouble code is stored in your vehicle’s computer. We can retrieve it and diagnose the issue before it becomes serious.
While the check engine light can indicate hundreds of different issues, some are more common than others:
Our diagnostic process identifies exactly which issue is affecting your vehicle.

Many shops simply read the trouble code and recommend replacing the indicated part. That approach often leads to unnecessary repairs and frustrated customers. Our process is different:
We connect to your vehicle’s computer and retrieve all stored trouble codes. This tells us where to start looking, but it’s just the beginning.
We interpret what the codes actually mean in the context of your specific vehicle and symptoms. A code is a clue, not a diagnosis.
Using specialized equipment, we test the specific systems and components indicated by the codes. This verifies the actual failure rather than guessing.
We identify not just what failed, but why it failed. This prevents repeat problems and ensures a lasting repair.
We explain what we found in plain English and provide a clear repair estimate. You’ll understand the problem and your options before any work begins.

Accurate diagnosis is the foundation of effective repair. Here’s why drivers trust us:
Our diagnostic fee covers the time and expertise needed to properly identify your problem. Diagnostic costs vary depending on the system being diagnosed.
Many parts stores offer free code reading, but a code is not a diagnosis. Without proper testing, you may end up replacing parts that aren’t actually failed, wasting money and not fixing the problem.
A solid light usually indicates a non-emergency, but you should schedule service soon. A flashing light requires immediate attention—pull over safely and call for help.
This can happen if associated systems develop a faulty condition, if there are multiple issues, or if a new problem developed. Our diagnostic process is thorough which minimizes this risk.
Don’t let that check engine light cause unnecessary stress—or lead to unnecessary repairs. Our diagnostic process is very thorough and finds the real problem so you can make informed decisions. Schedule your appointment today.
