It operates quickly and easily diagnoses fault codes, as well as offering capabilities for data logging and showing extra sensor readouts.

All in all...you can beat the value for the price. ### ⭐⭐⭐⭐ Easy to use, but the feature I needed was incomplete *by P***I on March 17, 2021* I already have a simple code reader, but picked this up as it is supposed to provide live data for O2 sensors. Unfortunately it does not read all the sensors. The first sensor, which is an Air/Fuel Ratio sensor is read, and the second sensor which is an O2 sensor is read, but the third sensor, also an O2 sensor is not listed in the display. Emailed manufacturer but never heard back. So while fine for most cars, this feature which I explicitly purchased this product for is incomplete. My auto is a 2005 Honda Civic Hybrid. On the plus side, it is a very good value compared to simple code readers. The display is easy to use and because the software is upgradable, should be able to get more features in the future, like that last O2 sensor being supported. ## Frequently Bought Together - EDIAG YA-201 Obd2 Scanner, Full OBD2 Modes Check Engine Code Reader After 1996 All OBDII/EOBD/KOBD/CAN Cars, O2 Sensor EVAP Systems, Battery Test,Live Data Stream,Plug & Play - LAUNCH X431 Creader Elite 2.0 FGC OBD2 Scanner,ECU Coding, Bi-Directional Scan Tool for Ford, for GM, for Chrysler,100+ Reset, Full System Diagnose, FCA AUTOAUTH, AUTOVIN, Lifetime Free Update - KINGBOLEN EL-50448 Automotive Tire Pressure Monitor Sensor 315/433 MHz TPMS Reset/Relearn Activation Tool Fit for GM Series Vehicle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/161535336-ediag-ya-201-obd2-scanner-full-obd2-modes-check-engine](https://www.desertcart.co.uk/products/161535336-ediag-ya-201-obd2-scanner-full-obd2-modes-check-engine) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-24*
