Toyota Tundra (2015 year). Manual — part 1877
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 and ECT / Utility / All Readiness.
9.
Input the DTC: P0013 or P0023.
10.
Check the DTC judgment result.

INSPECTION PROCEDURE
HINT:
If DTC P0013 is displayed, check the bank 1 VVT system for exhaust camshaft 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 transmission.
If DTC P0023 is displayed, check the bank 2 VVT system for exhaust camshaft circuit.
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 be helpful in determining whether the vehicle was moving or stationary, whether the engine
was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the
.
PROCEDURE
1.
CHECK DTC (DTC P0013 OR P0023)
(a) Connect the Techstream to the DLC3.
(b) Clear DTC after recording the freeze frame data and DTC.
(c) Turn the ignition switch off.
(d) Allow the engine to idle and check DTC.
(e) Check that P0013 or P0023 is not present.
OK:
P0013 or P0023 is not output.

DESCRIPTION
HINT:
If DTC P0014, P0015, P0024 or P0025 is present, check the VVT (Variable Valve Timing) system.
The Variable Valve Timing (VVT) system includes the ECM, OCV and VVT controller. The ECM sends a target
duty-cycle control signal to the OCV. This control signal regulates the oil pressure supplied to the VVT
controller. 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 OCV based on the
signals transmitted by several sensors. The VVT controller regulates the exhaust camshaft angle using oil
conditions. The ECM detects the actual exhaust valve timing using signals from the camshaft and crankshaft
position sensors, and performs feedback control. This is how the target exhaust valve timing is verified by the
ECM.
