WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2003 Toyota Tacoma, 2003 Toyota RAV4, 2003 Toyota Prius, 2003 Toyota Matrix, and 2003 Toyota MR2. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Variable Valve Timing (VVT) camshaft timing oil control valve may also be referred to as oil control valve for VVT, VVT Oil Control Valve (OCV) or camshaft timing oil control valve VVT.
WARNING:
On Prius, read service precautions before proceeding with service procedure. See SERVICE PRECAUTIONS .
- Remove No. 2 cylinder head cover located on top of engine, above ignition coils and valve cover (if necessary) for access to VVT camshaft timing oil control valve. VVT camshaft timing oil control valve is located at intake manifold side of cylinder head, near timing chain end of engine. See Figure-Fig 5. . To check VVT camshaft timing oil control valve resistance, disconnect electrical connector at VVT camshaft timing oil control valve.
- Using ohmmeter, check resistance between electrical terminals on VVT camshaft timing oil control valve. Ensure resistance is within specification. See VVT CAMSHAFT TIMING OIL CONTROL VALVE RESISTANCE table. If resistance is within specification, go to next step. If resistance is not within specification, replace VVT camshaft timing oil control valve. See VARIABLE VALVE TIMING CAMSHAFT TIMING OIL CONTROL VALVE

Application Ohms @ 68°F (20°C) Camry, Camry Solara, Celica, Corolla, Highlander, MR2, Prius & RAV4 6.9-7.9 ECHO 5.5-12.0 - To check VVT camshaft timing oil control valve operation, remove VVT camshaft timing oil control valve. See VARIABLE VALVE TIMING CAMSHAFT TIMING OIL CONTROL VALVE under VARIABLE VALVE TIMING SYSTEM in REMOVAL & INSTALLATION - 4-CYLINDER article.
- Note movement of valve inside VVT camshaft timing oil control valve while applying and disconnecting battery voltage and ground to terminals No. 1 and 2 on VVT camshaft timing oil control valve. See Figure and Fig 6 . 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 and Fig 6 . Replace VVT camshaft timing oil control valve if operation is not as specified.
