Ignition to on
Using a multimeter set on DC Volts. Connect black probe to an earth point or negative terminal on battery.
-Probe the TPS wiring with the red probe to find the signal wire which shoukd read around .4V, there will be a 12V power and Earth aswell.
-to set the TPS u need the signal to read .4-.5volts with no throttle. If it needs adjusting carefully loosen the tps bolts/screws. (caution these can be tricky to undo, and dont overtighten)
-signal should read around 4.5Volts at full throttle
