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, GX470, 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. On all vehicles except GX470, see IGNITION SYSTEM in REMOVAL & INSTALLATION - EXCEPT GX470. On GX470 , see IGNITION SYSTEM in REMOVAL & INSTALLATION - GX470.
