Tacoma & 4Runner

Disconnect electrical connector at camshaft position sensor. Camshaft position sensor is located at driver's side front corner of cylinder head, just in front of intake manifold. See Fig 5. Using ohmmeter, check resistance between electrical terminals on camshaft position sensor.
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 IGNITION SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION - 4-CYLINDER article. Reinstall electrical connector on camshaft position sensor.
