Works Well on Toyota RAV4

Worked on my 2009 Toyota RAV4 Limited. I got error p0137 which means Low Voltage on Bank 1 Sensor 2 (Downstream) on my Oxygen Sensor. So I replaced it and cleared the code and now it's working fine! This device saved me $300 that I would've lost to the dealer.

Simple to use, Read and Delete Codes

Tried in my husbands 2013 Toyota FJ Cruiser. He didn’t have a check engine light yet, just testing it out. Bought this for the future when an issue arises. But the screen was bright and clear, easy to read. All that had to be done was plugging it in, very simple to use. There we’re options to read the code, and to delete the code. Extremely user friendly for those that might have never used one of these readers before. This is an Extremely good product.
