My 94 FSM does not call out the resistance of the potentiometer. It uses voltage readings at the ecu. For a closed throttle it should be between 0.1 and 1.0V. For a closed throttle, terminals C & D should be shorted. For a WOT the FSM says that the voltage should be between 3.1 and 4.5V.
Hope that helps, Bruce _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
