DESCRIPTION

The VVT sensor system consists of a timing rotor (installed on each camshaft) and Magnetic Resistance Element (MRE) type VVT sensor. The timing rotor (camshaft) has 3 protrusions. When it rotates, the magnetic vector (direction of magnetic field) applied to the VVT sensor's MRE varies, which causes its resistance to vary. This varying resistance is converted to voltage, and then modified into a rectangular waveform with Hi (approximately 4 V) and Lo (approximately 1 V) outputs. As a result, the actual camshaft's position is detected and the position is output to the ECM.

DTC No.

MONITOR DESCRIPTION

If no signal is transmitted by the VVT sensor despite the engine revolting, the ECM interprets this as a malfunction of the sensor.
When the sensor output voltage remains less than 0.3 V, or more than 4.7 V for more than 5 seconds, the ECM sets a DTC.

INSPECTION PROCEDURE

Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
1.CHECK ECM TERMINAL VOLTAGE
A150299E01

  1. Inspect the ECM using an oscilloscope.

    1. While the engine is idling, check the waveform between the terminals of the ECM connector.

      Standard voltage:
      Tester Connection
      		Condition
      		Specified Condition
      E1-26 (EV1+) - E1-33 (EV1-)
      		Engine idling
      		Correct waveform appears as shown
      E3-22 (EV2+) - E3-29 (EV2-)
      		Engine idling
      E1-27 (NE+) - E1-34 (NE-)
      		Engine idling
