DESCRIPTION

The VVT sensor (for exhaust camshaft) (EV1, EV2 signal) consists of a magnet and MRE (Magneto Resistance Element).

The exhaust camshaft has a timing rotor for the VVT sensor. When the exhaust camshaft rotates, changes occur in the air gaps between the timing rotor 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 it to the ECM.

Then the ECM uses this data to control fuel injection duration, fuel injection timing and the Variable Valve Timing (VVT) system.

MONITOR DESCRIPTION

If no pulse signal is transmitted by the VVT sensor (for exhaust camshaft) despite the camshaft rotating, the ECM interprets this as a malfunction of the sensor.

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

MONITOR STRATEGY

Required Sensors/Components (Main)	VVT sensor (for exhaust camshaft)
Required Sensors/Components (Related)	Crankshaft position sensor
Frequency of Operation	Continuous

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON and turn the GTS on.
Start the engine.
Idle the engine for 10 seconds or more [A].
Enter the following menus: Powertrain / Engine / Trouble Codes [B].
Read the pending DTCs.
Tech Tips
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P0365, P0367, P0368, P0390, P0392 or P0393.

Check the DTC judgment result.

GTS Display	Description
NORMAL	DTC judgment completed System normal
ABNORMAL	DTC judgment completed System abnormal
INCOMPLETE	DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions
N/A	Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

Tech Tips

If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A, perform steps [A] and [B] again.

CAUTION / NOTICE / HINT

Tech Tips

If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.
Bank 1 refers to the bank that includes the No. 1 cylinder*.

*: The No. 1 cylinder is the cylinder which is farthest from the transaxle.
Bank 2 refers to the bank that does not include the No. 1 cylinder.
Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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.
