Does the trouble code display sequence using the trip odometer necessarily display all registered fault codes?
The "Check Engine" light is on in my 2001 SE wagon. The diagnostic display flashes "Dtc" / "none" and yet the amber light has been on for weeks now. The only trouble I have had is with the speed sensor, but it hasn't acted up for quite some time. I always tighten my fuel filler cap so I'm sure it's not that.
Will a proper OBD II code reader be able to tell me more than the dashboard display? Does anyone really know what all the things mean in the diagnostic sequence? While it's fun to make the gauges whirl around, I haven't gotten much use out of that feature.
