If a HI-SCAN is not used, connect a digital type voltmeter between connector 1 and 3.
Turn the ignition switch to the ON position (do not start engine) and check that the TP Sensor output voltage is as specified. If a HI-SCAN is used, press code No. 14 and read the voltage.
Standard value: 300 - 900 mV
