The exhaust camshaft has 3 teeth on its outer circumference. When the exhaust camshaft rotates, changes occur in the air gaps between the 3 teeth and MRE, which affects the magnetic field. As a result, the resistance of the MRE fluctuates. The VVT sensor converts the exhaust camshaft rotation data into pulse signals, uses the pulse signals to determine the camshaft angle, and sends the data to the ECM.

HINT:

EV1 and EV2 are the VVT sensor signals, and NE is the crankshaft position sensor signal.

MONITOR DESCRIPTION

If no signal is transmitted by the VVT sensor despite the engine running, or the rotations of the camshaft and crankshaft are not synchronized, the ECM interprets this as a malfunction of the sensor.

Also, when the sensor output voltage remains at below 0.3 V, or higher than 4.7 V for more than 4 seconds, the ECM stores a DTC.

CONFIRMATION DRIVING PATTERN

Start the engine and run it at idle for 10 seconds or more.

INSPECTION PROCEDURE

HINT:

Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, 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.

Bank 1 refers to the bank that includes the No. 1 cylinder*.
*: The No. 1 cylinder is the cylinder which is farthest from the transmission.

Bank 2 refers to the bank that does not include the No. 1 cylinder.

1.CHECK HARNESS AND CONNECTOR (SENSOR POWER SOURCE)
