I'm am selling one of my two Scan Gauge II . I bought this from Wayne maybe 6 years ago and used in my Camry Hybrid until I sold it earlier this year. The replacement did not need a Scan Guage. It is in very good condition and always worked. They are now listed at $159, and seem to last forever, so selling for $90 shipped lower 48 . Email me at dj63401 (at) gmail.com if want or need more info. Or PM on this site.
