Toyota Yaris: Sfi System / Camshaft Position "B" - Actuator Bank 1 Circuit Open (P001313)

Toyota Yaris XP210 (2020-2022) Reapir and Service Manual / Engine & Hybrid System / G16e-gts (engine Control) / Sfi System / Camshaft Position "B" - Actuator Bank 1 Circuit Open (P001313)

DESCRIPTION

The Variable Valve Timing (VVT) system 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 (for exhaust camshaft) 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 (for exhaust camshaft). The ECM changes the energizing time of the cam timing oil control solenoid assembly (for exhaust camshaft) duty-cycle in accordance with the camshaft position, crankshaft position, throttle position, etc.

DTC No.

Note

P001313

Camshaft Position "B" - Actuator Bank 1 Circuit Open

Open or short in cam timing oil control solenoid assembly (for exhaust camshaft) circuit (1 trip detection logic).

  • Open or short in cam timing oil control solenoid assembly (for exhaust camshaft) circuit
  • Cam timing oil control solenoid assembly (for exhaust camshaft)
  • ECM

Comes on

SAE: P0013

MONITOR DESCRIPTION

These DTCs are designed to detect an open or short in the cam timing oil control solenoid assembly (for exhaust camshaft) circuit. If the cam timing oil control solenoid assembly (for exhaust camshaft) duty-cycle is excessively high or low while the ignition switch is ON 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 ignition switch to ON.
  3. Turn the GTS on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the ignition switch off and wait for at least 30 seconds.
  6. Start the engine [A].
  7. Wait 5 seconds or more [B].
  8. Turn the GTS on.
  9. Enter the following menus: Powertrain / Engine / Trouble Codes [C].
  10. 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.
  11. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  12. Input the DTC: P001313.
  13. 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:

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

1.

CLEAR DTC

(a) Record the Freeze Frame Data.

Powertrain > Engine > Trouble Codes

(b) Clear the DTCs.

Powertrain > Engine > Clear DTCs

(c) Turn the ignition switch off and wait for at least 30 seconds.

2.

READ OUTPUT DTC (DTC P001313)

(a) Start the engine.

(b) Read the DTCs.
