Would you fail someone for a speedo sensor code? My car is a 95, but I'm pretty sure it is OBD2, is that possible?

It's not up to me. The Machine does it automaticly. Any code that effects emissions will trigger a failure. Vehicle speed /load effects how the computer adjusts fuel tables.

Most speedo gears are in the tailshaft housing. Are you sure you can't just drop the D/S and unbolt the tailshaft?(4 bolts).

You must be picturing a real car in your head, not this gas powered golfcart that I drive to school. Neon is FWD, uses a POS transaxle, no driveshaft, no tailshaft, no fun to drop.
