Camshaft Position Sensor: Sorento

NOTE: DO NOT use OBD-II Data Link Connector (OBD-II DLC) for lab scope power source as this will affect waveform.

Connect lab scope positive probe to ECM connector B01 terminal No. B10 (Blue wire). See Figure. Connect lab scope negative probe to ground. Set lab scope time to 20 milliseconds and voltage to 5 volts. Start engine and allow it to reach normal operating temperature. With engine at idle, compare CMP sensor waveform to normal CMP sensor waveform. See Figure. If waveform is erratic, replace CMP sensor.
