Rocker Arm Oil Control Solenoid Test

  1. Disconnect the rocker arm oil control solenoid connector.
  2. Measure the resistance between the rocker arm oil control solenoid 1P connector terminal (A) and body ground.
    • If the resistance is as specified, go to step  3.
    • If the resistance is not as specified, replace the rocker arm oil control solenoid.

      Resistance: 14-30 Ω

  3. Remove the rocker arm oil control solenoid/oil filter assembly (A) from the oil pump, and check the rocker arm oil control solenoid filter (B) for a restriction. If there is a restriction, replace the rocker arm oil control solenoid filter, the engine oil filter, and the engine oil.

  4. If the filter is not restricted, remove the rocker arm oil control solenoid (A) and push the valve (B) with your finger to check its movement. If the valve moves freely, it is normal, check the engine oil pressure (see OIL PRESSURE TEST ). If the valve binds or sticks, replace the rocker arm oil control solenoid assembly.
