Toyota Yaris: Sfi System / A Camshaft Position Actuator Bank 1 Circuit Open (P001013)

Toyota Yaris XP210 (2020-2024) Reapir and Service Manual / Engine & Hybrid System / G16e-gts (engine Control) / Sfi System / A Camshaft Position Actuator Bank 1 Circuit Open (P001013)

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

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Note
P001013	A Camshaft Position Actuator Bank 1 Circuit Open	Open or short in cam timing oil control solenoid assembly (for intake camshaft of) circuit (1 trip detection logic).	Open or short in cam timing oil control solenoid assembly (for intake camshaft of) circuit Cam timing oil control solenoid assembly (for intake camshaft of) ECM	Comes on	SAE: P0010

MONITOR DESCRIPTION

This DTC is designed to detect an open or short in the cam timing oil control solenoid assembly (for intake camshaft) circuit. If the cam timing oil control solenoid 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.

MONITOR STRATEGY

Required Sensors/Components	Cam 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.

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.	READ OUTPUT DTC (DTC P001013)

(a) Clear the DTC after recording the freeze frame data and DTC.

Powertrain > Engine > Clear DTCs

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

(d) Read the DTCs.

Powertrain > Engine > Trouble Codes

Result	Proceed to
P001013 is output	A
DTCs are not output	B

CHECK FOR INTERMITTENT PROBLEMS

2.	INSPECT CAM TIMING OIL CONTROL SOLENOID ASSEMBLY (FOR INTAKE CAMSHAFT)

REPLACE CAM TIMING OIL CONTROL SOLENOID ASSEMBLY (FOR INTAKE CAMSHAFT)

3.	CHECK HARNESS AND CONNECTOR (CAM TIMING OIL CONTROL SOLENOID ASSEMBLY (FOR INTAKE CAMSHAFT) - ECM)

(a) Disconnect the cam timing oil control solenoid assembly (for intake camshaft) connector.

(b) Disconnect the ECM connector.

Standard Resistance:

Tester Connection	Condition	Specified Condition
