DTC |
P001013 |
A Camshaft Position Actuator Bank 1 Circuit Open |
DESCRIPTION
The Variable Valve Timing (VVT) system consists of the ECM, camshaft timing oil control valve assembly and camshaft timing gear assembly.
The VVT system controls the camshaft timing oil control valve assembly to operate the camshaft timing gear assembly and optimize the intake valve timing according to driving conditions. This control is performed based on the air flow volume, throttle position, engine coolant temperature, etc. Based on signals from each sensor, the ECM controls the position of the camshaft timing control valve assembly to change the relative position of the camshaft, enhance the engine torque and fuel economy and decrease the exhaust gas emissions. Using signals from the camshaft position sensor, the ECM detects the actual valve timing and performs feedback control to optimize the valve timing.

A Camshaft Position Actuator Bank 1 Circuit Open |
Open or short in camshaft timing oil control valve assembly circuit (1 trip detection logic). |

MONITOR DESCRIPTION
This DTC is designed to detect an open or short in the camshaft timing oil control valve assembly circuit. If the camshaft timing oil control valve assembly duty-cycle is excessively high or low while the power switch is on (IG) or the engine is running, the ECM will illuminate the MIL and store this DTC.

CONFIRMATION DRIVING PATTERN
HINT:
-
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Turn the Techstream 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 Techstream on.
- Wait 5 seconds or more [A].
- Enter the following menus: Powertrain / Engine / Trouble Codes [B].
-
Read the 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: P001013.
-
Check the DTC judgment result.

Description
NORMAL
ABNORMAL
- DTC judgment completed
- System abnormal
INCOMPLETE
- DTC judgment not completed
- Perform driving pattern after confirming DTC enabling conditions
HINT:
- If the judgment result is NORMAL, the system is normal.
- If the judgment result is ABNORMAL, the system is malfunctioning.
-
[A] to [B]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- When clearing the permanent DTCs, do not disconnect the cable from the auxiliary battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

CAUTION / NOTICE / HINT
NOTICE:
-
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.)
Click here
-
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.

HINT:
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.
