Our take on the OBD2 Scanner Diagnostic Tool CR3008 Plus

The CR3008 Plus is a handheld OBD2 diagnostic scanner for cars, sold with batteries included. It reads and clears engine fault codes, shows live data, and checks emissions readiness before an inspection. It is a basic code reader rather than a bidirectional tool, so it suits drivers who want to see why the check engine light is on without paying a shop. It is widely sold at budget prices, and its latest best price sits near the low end of its recent range.

Best for
Drivers with a check engine light on
Pre-purchase used car checks
DIY oil-change and emissions readiness checks
Keeping in the glovebox for quick scans

Questions and answers

Is the CR3008 Plus worth it?
For a driver who just wants to read and clear engine codes at home, yes. If you need ABS, airbag or transmission diagnostics, spend more on a tool that covers those modules.
Will it work on my car?
It works on OBD2 cars, which in the US means most gasoline cars from 1996 and most diesels from 2004. Older or non-US vehicles may not be compatible.
Can it reset the check engine light?
Yes. It clears stored engine codes and turns off the light, but the light returns if the underlying fault is not fixed.
Does it check emissions readiness?
Yes. It shows which emissions monitors are ready, which helps before a smog or inspection test.
What comes in the box?
The scanner, a cable, batteries and a quick-start guide. No case or memory card is included.
When is it cheapest?
Budget code readers like this one tend to dip during holiday sales and back-to-school promotions. Check the price history before buying.
