FAQ's: Engine Diagnostics in Southaven MS

Tune-up, Fuel Injection Cleaning, Emission Repair

Why is my vehicle's check engine light on?

When your vehicle's dashboard check engine light comes on, it can signal anything from a loose gas cap to serious engine trouble. A diagnostic scan from a reputable auto repair shop will use advanced tools to read the error codes and pinpoint the issue—whether it’s an engine misfire, oxygen sensor failure, or emissions problem.

Is it ok to drive with the check engine light on?

If the light is solid, it is usually safe to drive short distances, but you should get it checked out soon by a professional auto repair shop. If the check engine light is flashing, it could indicate a severe misfire that may damage your catalytic converter—stop driving and get it inspected immediately.

How long does an engine diagnostic take?

Most auto repair shops can run a scan reader in about 15 to 30 minutes but to do an engine/computer diagnostic typically takes about an hour. but, deeper diagnostics (e.g., fuel pressure testing, compression checks) will usually take longer depending on the issue.

What exactly does an engine diagnostic include?

A full diagnostic typically covers:

Reading the trouble codes from the ECU
Checking fuel pressure and performance of the spark plugs
Inspecting the battery and charging system
Compression testing and sensor analysis

How much does an engine diagnostic cost?

Prices vary by shop but expect to pay $120–$200 for a full engine diagnostic.

Can an engine diagnostic fix the problem?

No. The engine diagnostics will identify the problem, but do not fix the problem. After the issue is pinpointed, the shop will recommend all necessary repairs—such as replacing a faulty sensor, ignition coil, or fuel injector. Most shops provide upfront pricing.

Will an engine diagnostic tell me if I need a new engine?

Yes, it will. Should the test reveal low compression across cylinders, severe internal damage, or catastrophic failure, the shop may recommend an engine replacement or engine rebuild.

Can I do an engine diagnostic myself?

Sure, you can use an OBD-II scanner to read basic codes on your own, but professional auto repair shops use advanced tools/scanners and techniques to interpret data and test components more thoroughly. When it comes to your vehicle’s engine, you should get a professional and reputable auto repair shop to perform the diagnostics.
