I just bought another 2001 Celica it had been swapped to a 2zz 6speed, (originally a 1zz auto) and the speedometer doesn’t work, do these transmission have the VSS sensor, or to I need to do more wiring. Idk if the ECU is from a GTS or not. I didn’t have time to get under it today, and was wondering if anyone else has had this issue. It is throwing the P500 code for the VSS. So any help and guidance would be great. The last form I posted on got no responses so I’m hoping this website actually has some decent people on it.
