FREE check engine code scans. Drive in Monday through Friday, 7:30 AM to 5:00 PM. No appointment needed.
Few things are as annoying as a check engine light that pops on out of nowhere. Sometimes it's minor. Sometimes it's the first warning of a problem that will get expensive if it's ignored. The only way to know is to find out what your vehicle's computer is reporting. At Red River Auto Care, 1616 Jimmie Davis Hwy in Bossier City, we scan check engine codes for free, and we'll tell you honestly what the code means and what it doesn't.
What the Check Engine Light Means
Modern vehicles constantly monitor the engine, emissions system, ignition, fuel system and sensors. When the computer sees a reading outside the expected range, it stores a diagnostic trouble code and turns on the check engine light. Common triggers include a loose or worn gas cap, failing oxygen sensors, misfires from worn spark plugs or ignition coils, vacuum leaks, mass airflow sensor problems, catalytic converter efficiency issues and evaporative emissions leaks.
Pay attention to how the light behaves. A steady light means the computer found a problem that should be checked soon. A flashing light usually means a severe misfire that can overheat and damage the catalytic converter. If your light is flashing, reduce your speed, avoid hard acceleration and get the vehicle checked as soon as possible. If the vehicle runs badly, overheats or loses power, it's safer not to drive it.

Free Code Scan vs. Full Diagnostic: The Honest Difference
We want you to know exactly what you're getting, so here's the straight answer.
A code scan connects a scan tool to your vehicle's diagnostic port and reads the trouble codes stored in the computer. It tells us which system flagged a problem and points us in the right direction. Our code scans are free.
A code is not a diagnosis. A code tells you what the computer noticed, not always why. For example, a code for a lean condition could be caused by a vacuum leak, a dirty airflow sensor, a weak fuel pump or a leaking intake gasket. A misfire code could be a spark plug, an ignition coil, a fuel injector or an internal engine problem. Replacing parts based on a code alone often wastes money and doesn't fix the light.
A full diagnostic goes further. Our technicians use the code as a starting point, then look at live sensor data, test the suspect components, check wiring and connections, and inspect for leaks or damage until we find the actual cause. That takes more time and expertise than reading a code, and it's how you avoid paying for parts you didn't need.
After your free scan, we'll explain what the code means for your vehicle. If the cause is clear, we'll tell you. If it needs more testing to pin down, we'll explain what that involves before any work begins, and you decide how to proceed.
Why Not Just Clear the Code?
Clearing a code turns the light off, but it doesn't fix anything. If the problem is still there, the light will come back, and in the meantime you lose the warning that something is wrong. Some issues behind a check engine light also affect fuel economy, emissions and drivability, and a few can lead to costly damage if left alone. It's worth knowing what's going on.
Symptoms That Often Come With the Light
- Rough idle, hesitation or stalling
- Loss of power or poor acceleration
- Worse fuel economy than usual
- A rotten-egg smell from the exhaust
- Hard starting or a no-start
- The engine running hot
Tell us about any symptoms when you drop off your vehicle. When the problem happens (cold starts, highway speeds, idling) helps our technicians track it down faster.
Repairs Backed by Our Warranty
Once we find the cause, we'll explain the repair in plain terms. Our repairs come with a lifetime warranty on parts and 2 years on labor. Many check engine causes overlap with other services we handle, like tune-ups, leak repair, cooling system repair and charging system repair. While you're in, we can also look at things like your brakes or your next oil change.

Frequently Asked Questions
Is the check engine code scan really free?
Yes. Red River Auto Care offers free check engine code scans. Drop in Monday through Friday, 7:30 AM to 5:00 PM. No appointment is needed.
What's the difference between a code scan and a diagnostic?
A code scan reads the trouble codes stored in your vehicle's computer and shows which system flagged a problem. A full diagnostic goes further, testing components, wiring and live data to find the actual cause. A code alone doesn't always tell you which part has failed.
Can I keep driving with my check engine light on?
If the light is steady and the vehicle drives normally, get it checked soon. If the light is flashing, or the vehicle runs badly, loses power or overheats, it's safer not to drive it. Our 24/7 towing line is (318) 470-7807.
Will a loose gas cap turn on the check engine light?
It can. A loose or worn gas cap can trigger an evaporative emissions code. It's one of many possible causes, so a scan is the best way to know.
Why not just clear the code?
Clearing the code turns off the light but doesn't fix the problem. If the issue is still there, the light will come back, and you lose the warning in the meantime.
Do I need an appointment for a code scan?
No. Just drive in to 1616 Jimmie Davis Hwy in Bossier City during business hours, Monday through Friday from 7:30 AM to 5:00 PM.
