The HOMPOW V520 is a plug-and-play Bluetooth OBD2 code reader for cars built since 1996 in the US (2000 in Europe and Asia). It reads and clears engine codes, streams live sensor data, runs I/M readiness, EVAP and O2 sensor tests, and shows battery and alternator voltage. A six-button layout and color display make it approachable for beginners, and it covers the core OBD2 modes most DIYers need. It is a basic tool, not a full bidirectional scanner: it won't do ABS, airbag or manufacturer-specific systems, and Bluetooth pairing adds a step versus a plug-in handheld. With 4.2 stars from 233 ratings, owners find it useful for check-engine jobs but some report pairing and app quirks.

Owners rate it 4.2 out of 5 and mostly find it a handy, low-cost way to read and clear check engine codes and check emissions readiness. Complaints center on Bluetooth pairing and app reliability rather than the diagnostics themselves.
The HOMPOW V520 is an OBD2 code reader for vehicles from 1996 and later. It plugs into the car's OBDII port and checks vehicle status in about 3 seconds. It scans the engine and emissions systems to find the cause of a check engine light.
It reads diagnostic trouble codes and clears them after repairs. It also shows real-time vehicle and sensor data on the screen. Built-in tests cover I/M emissions readiness, the EVAP system, oxygen sensors, and battery and alternator voltage.
The scanner has a large color display and six buttons. It is plug and play. It supports OBD-II, which cars have if built after 1996 in the US or 2000 in the EU and Asia. Older cars may have OBD-I or no port.
