Subfuel Solenoid Test

  1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
  1. Make sure the HDS communicates with the ECM/PCM. If it doesn't, go to the DLC circuit troubleshooting.
  1. Select the SUBFUEL SOLENOID ON and OFF in the INSPECTION MENU with the HDS.
  1. Check the clicking sound of subfuel solenoid by means of a stethoscope.
    • If any subfuel solenoid fails to make the typical clicking sound, check the sound again after replacing the subfuel solenoid.
    • If clicking sound is still absent, check the following.
    • -
      Whether there is wire breakage or poor connection in the YEL/BLK, YEL wire between subfuel pump relay and the subfuel solenoid.
      -
      Whether there is wire breakage or poor connection in the WHT wire between subfuel pump relay and the auxiliary under-dash fuse holder (15 A) fuse.
      -
      Whether there is any short-circuiting, wire breakage or poor connection in the wire between the subfuel solenoid and the ECM/PCM.
  1. Turn the ignition switch to LOCK (0).
  1. Disconnect the subfuel solenoid 2P connector.

  1. Measure the resistance between subfuel solenoid (A) terminals No. 1 and No. 2. There should be 10.3 Ω.
  1. Check the subfuel solenoid for dirt or rusty.
