2) Turn ignition on with engine off. Connect a DVOM to Dark Blue and Black wire terminals. With throttle at closed position, adjust TPS to obtain specified voltage. See TPS ADJUSTMENT VOLTAGE table.
3) Tighten screws and recheck readings. Turn ignition off. Remove jumper wires and reconnect harness connector to TPS.
