So far so good, download the app hook ed up the sensor found a bad coil number 3 cylinder took about 2 minutes.

So far, it showed a misfire in #6, sure enough the coil was corroded and plug was bad

A possible vacuum leak and a bad ignition coil

It identified faulty ignition coil in my 2006 rav4

Just used it again to pin down a bad ignition coil.
