Pick-Up Coil

NOTE: Samurai models utilize an integral crank angle sensor within pick-up coil.
  1. With ignition off, disconnect Yellow ECM connector. Using voltmeter, backprobe positive lead to terminal B1 of ECM Green connector (still connected to ECM). Backprobe negative lead to terminal A13 of disconnected Yellow ECM connector.
  2. Remove distributor cap, rotor, and shield cover. Check voltmeter reading when reluctor "window" is between magnet and Hall Effect pick-up coil. Voltmeter reading should be zero volts.
  3. Turn reluctor so that window is not between magnet and Hall Effect pick-up coil, thus breaking magnetic field. Voltmeter reading should be battery voltage.
  4. If results are not as indicated, inspect wiring and connections and repair as required. If wiring is okay, replace Hall Effect pick-up coil (crank angle sensor).
