TIL those cheap code readers from the auto parts store can sometimes see what my $4000 scanner misses.

Had a 2012 Civic with a weird intermittent misfire that my main tool showed as 'no codes present', but a $30 reader my buddy left in my truck picked up a pending P0304 after a 20 minute test drive, leading me right to a bad coil pack.

My old Innova 3100 caught a weird transmission code on my wife's Outback that my shop's fancy scanner just said was "no communication"... cost me like 60 bucks years ago. Sometimes the simple tools just listen better.

Wait, your shop's scanner just said "no communication" and charged you? That's wild lol
