The camshaft position sensor is installed on the front of the right cylinder head of the 5VZ-FE engine. The timing rotor has been integrated with the right bank camshaft timing pulley. While the camshaft rotates, the air gap between the protrusion on the timing rotor and the pick-up coil changes. This causes fluctuation in the magnetic field and generates a voltage signal in the pick-up coil.
- Disconnect the sensor harness.
- Measure the resistance between the sensor terminals. It should be between 835-1400 ohms.
- If not within specifications, replace the sensor.
REMOVAL & INSTALLATION
See Figure 1
- Drain the engine cooling system.
- Disconnect the upper radiator hose from the water outlet.
- Disconnect the power steering air hose from the clamp.
- Disconnect the three cord clamps of the spark plug wires from the belt cover.
- Remove the mounting bolts for the timing belt cover and gasket.
- Disconnect the camshaft position sensor harness.
- Remove the sensor.
- Attach the camshaft position sensor to the engine, tighten to 69 inch lbs. (8 Nm).
- Attach the wiring harness to the sensor.
- Install the timing belt cover tightening the six mounting bolts.
- Attach the power steering pump hose to the belt cover clamp.
- Install the spark plug wire clamps to the timing belt cover.
- Attach the upper radiator hose.
- Fill the cooling system, start the engine and top off the coolant.
- Check for leaks.
