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 material fluctuates. The VVT sensor converts the exhaust camshaft rotation data to pulse signals, uses the pulse signals to determine the camshaft angle, and sends the camshaft angle data to the ECM.

DTC No.	DTC Detection Condition	Trouble Area
P0365 P0390	There is no VVT sensor signal despite the crankshaft position sensor input being normal at an engine speed of 600 rpm or more (1 trip detection logic).	Open or short in VVT sensor (for exhaust side) circuit VVT sensor (for exhaust side) Exhaust camshaft Timing chain has jumped tooth ECM
P0367 P0392	Output voltage of the VVT sensor is below 0.3 V for 4 seconds (1 trip detection logic).	Open or short in VVT sensor (for exhaust side) circuit VVT sensor (for exhaust side) Exhaust camshaft Timing chain has jumped tooth ECM
P0368 P0393	Output voltage of the VVT sensor is higher than 4.7 V for 4 seconds (1 trip detection logic).	Open or short in VVT sensor (for exhaust side) circuit VVT sensor (for exhaust side) Exhaust camshaft Timing chain has jumped tooth ECM

Reference: Inspection using an oscilloscope

HINT:

The correct waveforms are as shown.

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

Equipment Setting	5 V/DIV. 20 msec./DIV.
Condition	Cranking or idling

MONITOR DESCRIPTION

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

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 TERMINAL VOLTAGE (SENSOR POWER SOURCE)

Disconnect the VVT sensor connector.

Turn the ignition switch to ON.

Measure the voltage according to the value(s) in the table below.

Standard Voltage:
Tester Connection Switch Condition Specified Condition
C121-3 (VC2) - Body ground Ignition switch ON 4.5 to 5.0 V
C122-3 (VC2) - Body ground Ignition switch ON 4.5 to 5.0 V
