Kickdown Cable

This procedure addresses the kickdown cable replacement on 2019-2024 Toyota RAV4 2.5L I4 FWD models. Note: This transmission uses electronic throttle control without a traditional kickdown cable.

Warnings

Tools required

Parts

• Throttle Position Sensor (if faulty) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Ensure engine is cool to the touch
3. Disconnect negative battery terminal and wait 2 minutes for airbag system to deplete
4. Verify symptoms are actually related to throttle response and not a mechanical cable (which does not exist on this model)

Procedure

1. 1

   Remove engine cover
   Grasp the engine cover at the front two corners and pull upward firmly to release the retaining grommets. Set cover aside.
2. 2

   Locate throttle body assembly
   Identify the throttle body on the driver's side of the intake manifold. Note there is no physical kickdown cable connected to this assembly - only electrical connectors and air intake ductwork.
   ℹ️Confirm absence of any kickdown cable. Modern electronic throttle control systems replaced cable-driven systems in this generation.
3. 3

   Inspect throttle position sensor connector
   Locate the electrical connector on the throttle body. Press the locking tab and disconnect the connector. Inspect terminals for corrosion, damage, or loose pins that could cause throttle signal issues mistaken for cable problems.
4. 4

   Check for diagnostic trouble codes
   If throttle response issues exist, connect an OBD-II scanner and check for codes P0120-P0124 (throttle position sensor), P0220-P0229 (throttle pedal position sensor), or transmission-related codes P0715-P0731. These electronic faults mimic symptoms previously caused by failed kickdown cables in older vehicles.
5. 5

   Perform throttle body inspection
   If replacing the throttle position sensor (integrated into throttle body), remove the two mounting bolts securing the throttle body to the intake manifold. Remove the throttle body and gasket. Clean mating surfaces if reinstalling same unit.
   Torque spec

   Sensor Bolts11 Nm (8 lb-ft)
6. 6

   Install throttle body assembly
   Position new gasket on intake manifold. Install throttle body and thread mounting bolts by hand. Torque bolts to specification in a criss-cross pattern.
   Torque spec

   Sensor Bolts11 Nm (8 lb-ft)
7. 7

   Reconnect electrical connector
   Plug the throttle position sensor connector back into the throttle body until the locking tab clicks into place. Ensure connection is secure with no gap between connector halves.
8. 8

   Perform throttle relearn procedure
   Reconnect battery negative terminal. Turn ignition to ON position without starting engine for 30 seconds. Turn ignition OFF for 10 seconds. Start engine and let idle for 5 minutes without touching accelerator pedal to allow ECU to relearn throttle baseline values.

Reassembly

1. Reinstall engine cover by aligning grommets with mounting posts and pressing down firmly until seated
2. Verify all electrical connectors are fully seated and locked
3. Double-check no tools or parts were left in engine bay

Verification

• Start engine and verify smooth idle with no surging or hunting
• Test drive vehicle through full throttle range verifying smooth acceleration and responsive downshifts
• Confirm no check engine light or transmission warning lights illuminate
• Verify transmission shifts occur at appropriate RPM ranges during moderate and heavy acceleration
• If issues persist, perform transmission adaptive learning reset using factory scan tool or drive cycle procedure in owner's manual
