DESCRIPTION
The VVT sensor (for exhaust side) consists of a magnet and MRE (Magneto Resistive Element).
The exhaust camshaft has a sensor plate with 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 magnet. As a result, the resistance of the MRE material fluctuates. The VVT sensor (for exhaust side) converts the exhaust camshaft rotation data to pulse signals, uses the pulse signals to determine the camshaft angle, and sends it to the ECM.
The crankshaft (crank angle sensor plate) has 34 teeth. The pickup coil generates 34 signals for each engine rotation. Based on combination of the VVT signals and NE signal, the ECM detects the crankshaft angle. Then the ECM uses this data to control fuel injection time and injection timing. Also, based on the NE signal, the ECM detects the engine speed.

MONITOR DESCRIPTION
If no signal is transmitted by the VVT sensor (for exhaust side) despite the engine revolving, 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 stores a DTC.

CONFIRMATION DRIVING PATTERN
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
-
Clear DTCs (even if no DTCs are stored, perform the clear DTC procedure) (See page
![2016 MY Sienna [12/2015 - 08/2016]; 2GR-FE (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR](/t3Portal/stylegraphics/info.gif)
).
- Turn the ignition switch off and wait for at least 30 seconds.
- Turn the ignition switch to ON and turn the Techstream on.
- Start the engine.
- Idle the engine for 10 seconds [A].
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P0365, P0367, P0368, P0390, P0392 or P0393.
-
Check the DTC judgment result [B].

-
If the test result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs (See page
).
HINT:
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.

CAUTION / NOTICE / HINT
HINT:
- Read freeze frame data using the Techstream. 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.
- If no problem is found by this diagnostic troubleshooting procedure, troubleshoot the engine mechanical system.
-
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.
