Error Code P001313 Toyota

Description:

– The Variable Valve Timing (VVT) system (for exhaust side) adjusts the exhaust valve timing to improve driveability. The engine oil pressure turns the VVT controller (camshaft timing exhaust gear assembly) to adjust the valve timing.

– The cam 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 (exhaust camshaft timing gear bolt assembly) and supply engine oil. The camshaft timing oil control valve assembly (exhaust camshaft timing gear bolt assembly) moves when the ECM applies 12 V to the cam timing oil control solenoid assembly. The ECM changes the energizing time of the cam 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 cam timing oil control solenoid assembly circuit. If the cam timing oil control solenoid 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:

1. Connect the GTS to the DLC3.

2. Turn the power switch on (IG).

3. Turn the GTS on.

4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

5. Turn the power switch off and wait for at least 30 seconds.

6. Turn the power switch on (IG).

7. Turn the GTS on.

8. Put the engine in Inspection Mode (Maintenance Mode).

9. Start the engine.

10. Wait 5 seconds or more.

11. Enter the following menus: Powertrain / Engine / Trouble Codes.

12. 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.

13. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

14. Input the DTC: P001313.

15. 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.
