Celica 1.8L 2ZZ-GE
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Toyota Tacoma, 2002 Toyota RAV4, 2002 Toyota Prius, 2002 Toyota MR2, and 2002 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
- Remove No. 2 cylinder head cover located on top of engine, above ignition coils and valve cover. To check VVL oil control valve resistance, disconnect electrical connector at VVL oil control valve. VVL oil control valve is located at intake manifold side of cylinder head, near flywheel end of engine. See Figure.
- Using ohmmeter, check resistance between electrical terminals on VVL oil control valve. Resistance should be 6.9-7.9 ohms at 68°F (20°C). If resistance is within specification, go to next step. If resistance is not within specification, replace VVL oil control valve. See VARIABLE VALVE LIFT OIL CONTROL VALVE under VARIABLE VALVE LIFT SYSTEM in REMOVAL, OVERHAUL & INSTALLATION - 4-CYLINDER article.
- To check VVL oil control valve operation, remove VVL oil control valve. See VARIABLE VALVE LIFT OIL CONTROL VALVE under VARIABLE VALVE LIFT SYSTEM in REMOVAL, OVERHAUL & INSTALLATION - 4-CYLINDER article.
- Note movement of valve inside VVL oil control valve while applying and disconnecting battery voltage and ground to terminals No. 1 and 2 on VVL oil control valve. See Figure. Valve should move outward toward end of assembly opposite electrical connector with voltage applied and should move inward toward electrical connector end of assembly with voltage not applied. See Figure. Replace VVL oil control valve if operation is not as specified.
