Code 1-3-1: Ignition System RPM Signal

Turn ignition off. Disconnect fuel system ECU connector and remove protective sleeve. Connect a voltmeter between harness side of terminal No. 1 (Yellow/Gray wire) and ground. Run starter motor. Voltage reading should be 5-7 volts. If reading is not 5-7 volts, check wiring between ignition ECU and fuel injection ECU. If wiring is okay, replace ignition ECU.
