An indispensable tool for hybrid vehicles.

Very good tool, would give 5 stars. I removed 1 star because the temporary "prefix" is open circuited. You have to constantly move around the connector for it to make a connection and apparently OTC doesn't sell this part separately. When I got it to work, I turned my AC up to 74 degrees and the meter read 74 degrees.

Pros
