Camshaft Position Sensor Resistance

Disconnect electrical connector at camshaft position sensor. See CAMSHAFT POSITION SENSOR LOCATION table. See Fig 1-Fig 3 .

CAMSHAFT POSITION SENSOR LOCATION

Application

Ohms

ES300 & RX300

⁽¹⁾ Two Sensors Are Used, One At Rear Of Each Cylinder Head, Just Below Valve Cover

GS300 & IS300

Just Above Intake Manifold At Rear Corner Of Cylinder Head

GS430, LS430, LX470 & SC430

Behind Driver's Side Upper Timing Belt Cover, Near Camshaft Sprocket With Electrical Connector Near Front Of Upper Timing Belt Cover

⁽¹⁾	Camshaft position sensors may also be referred to as Variable Valve Timing (VVT) sensors.

Using ohmmeter, check resistance between electrical terminals on camshaft position sensor. See Fig 1-Fig 3 . 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 SYSTEM in REMOVAL, OVERHAUL & INSTALLATION article.
