38. Install the rocker arm oil control solenoid/oil filter assembly (A), with a new rocker arm oil control solenoid filter (B).
39. Install the oil pan (see «OIL PAN INSTALLATION»(ref-348540-S13051466612009112400000) ).
40. Install the crankshaft position (CKP) sensor (see «CMP SENSOR REPLACEMENT»(ref-348508-S19204905652009112400000) ).
