[QUOTE="torch, post: 1471796, member: 1295"] New kill switch? Why? It should be a simple on-off switch, did you test it with an ohmmeter? Assuming it's a simple potentiometer you are probably OK so long as you didn't do something silly like connect the battery directly to the contacts. Of course, if it's some sort of electronic accelerometer then it could be damaged but such things were less common back at the turn of the century when this was designed. One thought that occurred to me: Your codes are 13 (Intake Air Pressure), 15 (Throttle Position sensor), 21 (Water Temperature Sensor), and 41 (Lean Angle Sensor). All four of those have a Black/Blue wire that shares a common connection to the ECU with the others. So do the Atmospheric Temp, Crankshaft Position, Cylinder ID, Speed and Intake Air Temp sensors. But so far as I can see from the fault codes table there's no monitoring of the wiring to those others. So maybe the problem is a break or short in the B/L wire to the ECU or a defective ECU.
