DESCRIPTION
The VVT sensor (VV1, VV2 signal) consists of a magnet and MRE (Magneto-Resistive Element).
The intake camshaft has a timing rotor for the VVT sensor. When the intake 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 camshaft rotation data to pulse signals, uses the pulse signals. The ECM uses the pulse signals to determine the camshaft angle. Then the ECM uses this data to control fuel injection duration and injection timing.

-
The correct waveform is as shown.
-
VV1 stands for the VVT sensor signal (for intake camshaft of bank 1), and VV2 stands for the VVT sensor signal (for intake camshaft of bank 2).

Tester Range 5 V/DIV., 20 ms./DIV. Condition Idling with warm engine -
MONITOR DESCRIPTION
If the output voltage transmitted by the VVT sensor (for intake camshaft) remains low or high, the ECM interprets this as a malfunction in the sensor circuit, illuminates the MIL and stores a DTC.
MONITOR STRATEGY
| Required Sensors/Components (Main) | VVT sensor |
| Required Sensors/Components (Related) | Crankshaft position sensor |
| Frequency of Operation | Continuous |
CONFIRMATION DRIVING PATTERN
-
Connect the GTS to the DLC3.
-
Turn the power switch on (IG).
-
Turn the GTS on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the power switch off and wait for at least 30 seconds.
-
Turn the power switch on (IG).
-
Turn the GTS on.
-
Put the engine in Inspection Mode (2WD for measuring Exhaust Gas).
-
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.
Tip:
-
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: P034011, P034015, P034511 or P034515.
-
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
Tip:
-
If the judgment result shows NORMAL, the system is normal.
-
If the judgment result shows ABNORMAL, the system is malfunctioning.
-
If the judgment result shows INCOMPLETE, perform steps [A] and [B] again.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
-
Vehicle Control History may be stored in the hybrid vehicle control ECU if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.
(Select Powertrain in Health Check and then check the time stamp data.)
-
If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.
-
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 transmission.
-
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.

CHECK HARNESS AND CONNECTOR
Tip:Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
-
Disconnect the VVT sensor (for intake camshaft) connector.
-
Turn the power switch on (IG).
-
