Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the appropriate KS.
    NOTE: If the voltage is not within the specified range on either circuit, test for a wire to wire short, short to ground or voltage between the KS circuits.
  2. Ignition ON, test for 2-3 volts between the signal circuit terminal 1 and ground.
    • If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuits/connections test normal, replace the ECM.
    • If greater than the specified range, test the signal circuit for a short to voltage. If the circuits/connections test normal, replace the ECM.
  3. Test for 2-3 volts between the low reference circuit terminal 2 and ground.
    • If less than the specified range, test the low reference circuit for a short to ground or an open/high resistance. If the circuits/connections test normal, replace the ECM.
    • If greater than the specified range, test the low reference circuit for a short to voltage. If the circuits/connections test normal, replace the ECM.
  4. If all circuits/connections test normal, test or replace the KS sensor.
