Know what your car is reporting.
FuelFixScan plugs into your car's OBD2 port and shows the stored diagnostic codes on its own screen, so you can decide what to do next.


A code reader with its own screen.
No phone or app needed. Plug it in and read.
Read trouble codes
See the diagnostic codes your vehicle's computer has stored.
Clear codes after a repair
Reset the check engine light once the fault has been dealt with. Clearing a code does not fix the problem.
View live data
Real-time readings from the sensors your vehicle supports.
Check readiness and vehicle info
I/M readiness status and vehicle details, where your car supports them.
What the codes can mean.
A warning light on its own does not say much. Pick a commonly seen code to see what it can point to.
Catalyst efficiency below threshold
The catalytic converter may not be cleaning exhaust as well as it should. The cause can be the converter itself or an oxygen sensor.
These are general definitions and the exact cause varies by vehicle. A code is a starting point, not a complete diagnosis, and complex issues should be checked by a qualified mechanic.

A typical garage diagnostic costs more than this scanner.
Many garages charge a fee just to find out why a warning light is on.
Source: RepairPal 2026 national estimate for a check-engine-light diagnosis. Actual prices vary by shop, location, and vehicle. FuelFixScan reads codes; it does not repair your car, and a garage's diagnosis can involve more than reading a code. Knowing the code first means you go into that conversation better informed.
Three steps.
Plug it in
Find the OBD2 port, usually under the dashboard on the driver's side, and connect FuelFixScan.
Run the scan
Turn the ignition on. FuelFixScan reads your vehicle's computer and lists any stored codes.
Know the code
Look up what it means, then decide whether it is a DIY fix or a visit to a garage.
Choose how many.
Same scanner in every option. Multi-packs cost less than buying the same number separately. Shipping and any taxes are shown at checkout.

Compatibility.
FuelFixScan works with OBD2-compliant vehicles. In the US, that means cars and light trucks from 1996 onward.
Outside the US it depends on the vehicle. In Europe, petrol cars from 2001 and diesels from 2004 use the equivalent EOBD standard. Protocol support can vary, so please check your vehicle's compatibility before ordering.
Common questions.
Do I need an app or a phone?
No. FuelFixScan has its own built-in screen and menu, so you can read codes without a phone or app.
Can it fix my car, or just read codes?
It reads and displays codes, and can clear them after a repair. It does not repair anything. If the underlying fault is still there, the warning light and the code are likely to come back.
How much is shipping?
Shipping options and costs, along with any taxes, are shown at checkout before you pay. Whether we can deliver depends on your address.
Is it a one-time purchase?
Yes. You pay once for the scanner. There is no subscription and no per-scan fee.
What if it isn't right for me?
