DESCRIPTION
The Variable Valve Timing (VVT) system includes the ECM, camshaft timing oil control valve assembly (for exhaust side) and camshaft timing exhaust gear assembly. The ECM sends a target duty-cycle control signal to the camshaft timing oil control valve assembly (for exhaust side). This control signal regulates the oil pressure supplied to the camshaft timing exhaust gear assembly. Camshaft timing control is performed according to engine operating conditions such as the intake air volume, throttle valve position and engine coolant temperature. The ECM controls the camshaft timing oil control valve assembly (for exhaust side), based on the signals transmitted by several sensors. The camshaft timing exhaust gear assembly regulates the exhaust camshaft angle using oil pressure through the camshaft timing oil control valve assembly (for exhaust side). As a result, the relative positions of the camshaft and crankshaft are optimized, the engine torque and fuel economy improve, and the exhaust emissions decrease under overall driving conditions. The ECM detects the actual exhaust valve timing using signals from the VVT sensor and crankshaft position sensor, and performs feedback control. This is how the target intake valve timing is verified by the ECM.

MONITOR DESCRIPTION
This DTC is designed to detect an open or short in the camshaft timing oil control valve assembly (for exhaust side) circuit. If the camshaft timing oil control valve assembly (for exhaust side) duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and store the 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.
- Wait 5 seconds.
- Enter the following menus: Powertrain / Engine / Trouble Code.
-
Read pending DTCs.
HINT:
- 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: P0013 or P0023.
-
Check the DTC judgment result.
Techstream 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's memory limit
HINT:
If the judgment result shows ABNORMAL, the system has a malfunction.
-
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.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
HINT:
- If DTC P0013 is output, check the VVT system (for exhaust camshaft of bank 1) circuit.
- If DTC P0023 is output, check the VVT system (for exhaust camshaft of bank 2) circuit.
-
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 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.
