- Two camshaft position sensors are used. Camshaft position sensors are located at flywheel end of each cylinder head, just below valve cover. See Fig 1. Camshaft position sensors may also be referred to Variable Valve Timing (VVT) sensors. Remove necessary components for access to electrical connector at camshaft position sensor. Disconnect electrical connector at camshaft position sensor.
- Using ohmmeter, check resistance between electrical terminals on each camshaft position sensor. See Fig 1. Ensure camshaft position sensor resistance is within specification. See CAMSHAFT POSITION SENSOR RESISTANCE table. Replace camshaft position sensor if resistance is not within specification. See CAMSHAFT POSITION SENSOR under IGNITION SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION - V6 & V8 article. Reinstall electrical connector on camshaft position sensor.
