Best OBD2 Scanners Under $100

You do not need to spend hundreds to read check engine codes and live data. These FOXWELL scanners deliver solid engine diagnostics under $100 — check Amazon for current pricing on each model.

1 Cheapest option: FOXWELL NT201

Read and clear engine codes, view live data, and run smog readiness monitors. Best for drivers who only need to know why the MIL is on and whether it is safe to drive.

2 Best under $100 overall: FOXWELL NT301

Live data graphs, freeze frame, battery voltage test, and a protective case. The NT301 is the top pick when you want more diagnostic depth without crossing the $100 line.

3 Add battery testing: BT100 Pro

Pair a code reader with the FOXWELL BT100 Pro to test CCA, voltage, and battery health before blaming the alternator or starter for no-start issues.

4 What you give up under $100

Budget scanners do not scan ABS, SRS, or transmission modules and cannot run bidirectional active tests. Upgrade to NT604 or NT624 when you need full-system access.
