A25A-FXS (ENGINE CONTROL): SFI SYSTEM (w/o Canister Pump Module): P001313; Camshaft Position "B" - Actuator Bank 1 Circuit Open; 2019 - 2020 MY RAV4 HV [11/2018

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

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.
Put the engine in Inspection Mode (Maintenance Mode).
Click here
Start the engine.
Wait 5 seconds or more.
Enter the following menus: Powertrain / Engine / Trouble Codes.
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: P001313.

Check the DTC judgment result.

Techstream 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.

NOTICE:

Vehicle Control History may be stored in the hybrid vehicle control ECU assembly 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.

If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, 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.

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.
