Camshaft Position "B" - Timing Over-Retarded Bank 1

Exhaust valve timing is stuck at a certain value when in the retard range (1 trip detection logic).

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, cam timing oil control solenoid assembly, camshaft timing oil control valve assembly (exhaust camshaft timing gear bolt assembly) and camshaft timing exhaust gear assembly. The ECM sends a target duty-cycle control signal to the cam timing oil control solenoid assembly. The camshaft timing oil control valve assembly (exhaust camshaft timing gear bolt assembly) is operated to control the oil pressure supplied to the camshaft timing exhaust gear assembly based on this signal. The camshaft timing 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 the actual exhaust valve timing are small, the ECM interprets this as the camshaft timing exhaust gear assembly stuck malfunction and stores a DTC.

  • Example:
  • DTC P001400 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 cam timing oil control solenoid assembly is forcibly activated for 60 seconds or more (Condition "B").
  • DTC P001500 is stored when the following conditions "C" and "D" are met:
    1. It takes 5 seconds or more to change the valve timing by 5°CA (Condition "C").
    2. After the above condition is met, the cam timing oil control solenoid assembly is forcibly activated for 9.5 seconds or more (Condition "D").

These DTCs indicate that the camshaft timing exhaust gear assembly cannot operate properly due to a camshaft timing oil control valve assembly (exhaust camshaft timing gear bolt assembly) malfunction or the presence of foreign matter in the camshaft timing oil control valve assembly (exhaust camshaft timing gear bolt assembly).

P0014: Advanced Camshaft Timing

Both of the following conditions are met

-

Deviation of actual valve timing and target valve timing

More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit

Valve timing

No change at advanced valve timing

P0015: Retarded Camshaft Timing

Both of the following conditions are met

-

Deviation of actual valve timing and target valve timing

More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit

Valve timing

No change at retarded valve timing

If the difference between the target and actual camshaft timing is greater than the specified value, the ECM operates the VVT actuator for 10 seconds by applying and releasing oil pressure. Then, the ECM monitors the camshaft timing change for 10 seconds.

CAUTION / NOTICE / HINT

NOTICE:

  • Vehicle Control History may be stored in the hybrid vehicle control ECU assembly 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.

    Click here

    (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 assembly, 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.

HINT:

  • DTC P001400 or P001500 may be stored when foreign matter in the engine oil is caught in some parts of the system. The DTC will remain stored even if the system returns to normal after a short time. This foreign matter may then be captured by the oil filter.
  • 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.
