Rocker Arm Oil Control Solenoid Assembly Inspection
2009 Acura MDXSECTION Rocker Arm Oil Control Solenoid Assembly Inspection
- 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.
- 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 engine oil is OK, replace the rocker arm oil control solenoid (see ROCKER ARM OIL CONTROL SOLENOID REPLACEMENT ). If the valve binds or sticks, replace the rocker arm oil control solenoid assembly.
