Frequently Asked Questions
Q: Will a $50 OBD2 scanner work on my car?
A: Most likely yes. A majority of scanners under $50 support standard OBDII protocols used since 1996. Check the product notes for specific protocol support if you have an uncommon vehicle.
Q: Do cheap OBD2 scanners read all codes?
A: Cheap scanners read generic (P0, P2, P3, U0) codes and many manufacturer codes. They may not support deep manufacturer-specific modules like ABS or airbag systems.
Q: Should I buy a Bluetooth or wired scanner?
A: Choose based on preference. Bluetooth models let you use a phone for graphs and logging. Wired handheld units often work immediately, need no phone, and are simpler for many users.
Q: Can these scanners help pass a smog test?
A: Some scanners include I/M readiness checks so you can verify monitors are set before testing. They can’t clear readiness — only driving cycles can reset monitors.
