DESCRIPTION

Refer to DTC P0013 (See page 2016 MY Sienna [12/2015 - 08/2016]; 2GR-FE (ENGINE CONTROL): SFI SYSTEM: P0013,P0023; Camshaft Position "B" Actuator Circuit / Open (Bank 1)+ ).

DTC No.

DTC Detection Condition

Trouble Area

P0014

P0024

Exhaust valve timing is stuck at a certain value when in the advance range

(2 trip detection logic)

  • Valve timing
  • Camshaft timing oil control valve assembly (for exhaust side of bank 1, 2)
  • Oil control valve filter
  • Oil pipe
  • Camshaft timing exhaust gear assembly (bank 1, 2)
  • ECM

P0015

P0025

Exhaust valve timing is stuck at a certain value when in the retard range

(1 trip detection logic)

  • Valve timing
  • Camshaft timing oil control valve assembly (for exhaust side of bank 1, 2)
  • Oil control valve filter
  • Oil pipe
  • Camshaft timing exhaust gear assembly (bank 1, 2)
  • ECM

MONITOR DESCRIPTION

  • The ECM optimizes the exhaust valve timing using the Variable Valve Timing (VVT) system to control the exhaust camshaft. The 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. This control signal regulates the oil pressure supplied to the camshaft timing exhaust gear assembly (for exhaust side). The camshaft timing exhaust gear assembly can advance or retard the exhaust camshaft.
  • If the difference between the target and actual exhaust valve timing is large, and changes in actual exhaust valve timing are small, the ECM interprets this as the camshaft timing exhaust gear assembly stuck malfunction and stores a DTC.
  • Example:
  • A DTC is stored when the following conditions "A" and "B" are met:
    1. It takes 5 seconds or more to change the valve timing by 5°CA (Condition "A").
    2. After the above condition is met, the camshaft timing oil control valve assembly is forcibly activated 10 seconds (Condition "B").
  • DTCs P0014 and P0024 (advanced camshaft timing) are subject to 2 trip detection logic.
  • DTCs P0015 and P0025 (retarded camshaft timing) are subject to 1 trip detection logic.
  • These DTCs indicate that the camshaft timing exhaust gear assembly cannot operate properly due to camshaft timing oil control valve assembly (for exhaust side) malfunctions or the presence of foreign objects in the camshaft timing oil control valve assembly (for exhaust side).

  • If DTC P0014 or P0015 is output, check the VVT system (for exhaust camshaft of bank 1) circuit.
  • If DTC P0024 or P0025 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.
  • DTC P0014, P0015, P0024 or P0025 may be stored when foreign objects in the engine oil are caught in some parts of the system. The DTC will remain stored even if the system returns to normal after a short time. Those foreign objects may then be captured by the oil filter.
  • 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.
