Revolution Sensor

WARNING: This page is about a different car, the 2007 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove revolution sensor.
  2. Connect 12V power supply and 100 Ω resistance to the terminal. (Do not mistake polarity)
  3. Inspect the voltage of HIGH and LOW signal by shaking magnetic body from side to side at revolution sensor tip [gap is within 5mm (0.20 in)].
    CAUTION: Make sure to shake direction from bolt hole to sensor-self when shaking magnetic body. If not, voltage value cannot change.
