A25A-FXS (ENGINE CONTROL): SFI SYSTEM (w/o Canister Pump Module): P16B09F; Actuator Cut Circuit Stuck Off; 2019 - 2020 MY RAV4 HV [11/2018

The ECM monitors the operation of the throttle actuator. When a malfunction is detected in the throttle actuator cut circuit immediately after the power switch is turned off, the ECM illuminates the MIL and stores a DTC.

MONITOR STRATEGY

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 Techstream off.
Turn the power switch off.
Disconnect the Techstream.
Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.
Connect the cable to the negative (-) auxiliary battery terminal.
Connect the Techstream to the DLC3.
Turn the power switch on (IG).
Turn the Techstream on.
Wait 1 second 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.

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.

PROCEDURE

Powertrain > Engine > Clear DTCs

(a) Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.
