7GR-FKS ENGINE CONTROL SFI SYSTEM P001013 A Camshaft Position Actuator Bank 1 Circuit Open P002013 Camshaft Position "A" Actuator Bank 2 Circuit Open
DESCRIPTION
The Variable Valve Timing (VVT) system adjusts the intake valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing.
The camshaft timing oil control solenoid assembly operates according to signals received from the ECM to control the position of the camshaft timing oil control valve assembly and supply engine oil. The camshaft timing oil control valve assembly moves when the ECM applies 12 V to the camshaft timing oil control solenoid assembly. The ECM changes the energizing time of the camshaft timing oil control solenoid assembly (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.

MONITOR DESCRIPTION
This DTC is designed to detect an open or short in the camshaft timing oil control solenoid assembly (for intake camshaft) circuit. If the camshaft timing oil control solenoid duty-cycle is excessively high or low while the ignition switch to ON or the engine is running, the ECM will illuminate the MIL and store this DTC.
MONITOR STRATEGY
| Required Sensors/Components | Camshaft timing oil control solenoid assembly (for intake camshaft) |
| Frequency of Operation | Continuous |
CONFIRMATION DRIVING PATTERN
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for at least 30 seconds.
Start the engine [A].
Wait 5 seconds or more [B].
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes [C].
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 or P002013.
Check the DTC judgment result.
| GTS 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 |
- HINT:
- ·
If the judgment result is NORMAL, the system is normal.
·If the judgment result is ABNORMAL, the system has a malfunction.
·If the judgment result is INCOMPLETE, perform steps [A] through [C] again.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
- HINT:
- ·
If DTC P001013 is output, check the VVT system (for intake camshaft of bank 1) circuit.
·If DTC P002013 is output, check the VVT system (for intake 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 transmission.
·Bank 2 refers to the bank that does not include the No. 1 cylinder.
·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.
PROCEDURE
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTC after recording the Freeze Frame Data and DTC.
