The Thinkcar Thinkcheck is a handheld OBD2 code reader with a 5-inch color touchscreen, built-in battery, and Bluetooth and WiFi. It reads and clears engine codes on most cars and light trucks sold in the US since 1996. At $144.17 on eBay as of November 8, 2026, it sits at the low end of its recent range, with 14 stores listing it new. It is a general-purpose reader rather than a dealer-level tool, so it covers engine and emissions codes but not deep body or chassis systems.

Owner feedback on the Thinkcheck is thin, and what exists is mixed. Buyers like the large touchscreen and easy code reading, but some find the app pairing and limited system coverage frustrating.
