Who this guide is for
OBD2 scanners that read check engine codes on 1996 and newer cars, from glovebox readers to full diagnostic tools. We focus on what each pick does best, what it costs in the US and who should skip it.
How we chose
We compared manufacturer specifications, documentation, warranty terms and typical US prices, then gave each product a clear Buy, Consider or Skip verdict for the people it suits.
What to look for
- All US cars from 1996 onward have an OBD2 port.
- Basic readers show engine codes; better tools read ABS, airbag and transmission codes.
- Check for subscription costs.
- Live data helps diagnose problems before you buy parts.
Buying in the US
Some auto parts stores in the US read codes for free, but a scanner lets you check codes any time and see live data.
Frequently asked questions
Will an OBD2 scanner work on my car?
Yes, if it was sold in the US in 1996 or later.
Can I clear a check engine light myself?
Yes, but fix the cause first or the light will return.
Do I need a subscription?
BlueDriver and ANCEL work without one. FIXD needs a subscription for most features.
