This procedure covers the replacement of the Throttle Position Sensor (TPS) on the 2019-2024 Toyota RAV4 with the 2.5L I4 gasoline engine.
Warnings
⚠Allow engine to cool completely before beginning work to avoid burns from hot components
ℹ️Disconnecting the battery will erase radio presets and may require window auto-up/down reinitialization
⚠Do not force the TPS during installation as improper alignment can damage the throttle body shaft
Tools required
10mm socket and ratchetEssential
Phillips screwdriver (small)Essential
Torque wrench (1-10 Nm range)Essential
Panel trim tool
Flashlight or work light
Parts
- Throttle Position Sensor × 1 — Use OEM specification
- TPS mounting screw seal washers (if equipped) × 2 — Use OEM specification
Preparation
- Park vehicle on level surface and apply parking brake
- Allow engine to cool completely
- Disconnect negative battery terminal and wait 90 seconds for system discharge
- Remove engine cover by pulling upward on clips
Procedure
- 1Access the throttle body assemblyLocate the throttle body on the intake manifold near the center of the engine bay. Remove the air intake duct by loosening the hose clamp at the throttle body and disconnecting any breather hoses. Move the duct aside for access.
- 2Disconnect TPS electrical connectorLocate the TPS electrical connector on the side of the throttle body. Press the locking tab and carefully pull the connector straight off the sensor. Inspect connector terminals for corrosion or damage.
- 3Remove the old TPSUsing a Phillips screwdriver, remove the two TPS mounting screws. Note the orientation of the sensor before removal. Carefully pull the TPS straight off the throttle body shaft. Do not rotate or force the sensor during removal.Torque specTPS Screws3 Nm (2 lb-ft)
- 4Inspect throttle body shaftExamine the throttle body shaft for wear, scoring, or damage. Check that the shaft rotates smoothly without binding. Clean any debris from the mounting surface using a clean, lint-free cloth. Do not spray cleaners directly into the throttle body.
- 5Install new TPSAlign the new TPS with the throttle body shaft, ensuring the sensor tab engages with the shaft D-shape properly. The sensor should slide on easily without force. If equipped, install new seal washers on the mounting screws.⚠Verify correct alignment before tightening screws - misalignment will cause incorrect sensor readings
- 6Torque TPS mounting screwsInstall both TPS mounting screws finger-tight, then torque in a cross pattern to specification using a torque wrench. Do not overtighten as this can damage the sensor housing.Torque specTPS Screws3 Nm (2 lb-ft)
- 7Reconnect electrical connectorPush the electrical connector onto the TPS until it clicks into place. Verify the locking tab is fully engaged by gently pulling on the connector.
- 8Reinstall air intake componentsReposition the air intake duct and tighten the hose clamp at the throttle body. Reconnect any breather hoses that were removed. Ensure all connections are secure and properly seated.
- 9Reconnect battery and clear codesReconnect the negative battery terminal. Turn the ignition to ON position without starting the engine. Wait 10 seconds, then turn ignition OFF. Repeat this cycle three times to allow the ECU to relearn throttle position values.
Reassembly
- Reinstall engine cover by pressing down on clips until they snap into place
- Verify all hose clamps and connections are tight
- Check that no tools or parts were left in the engine bay
Verification
- Start the engine and verify it idles smoothly without surging or stalling
- Check that no warning lights are illuminated on the instrument cluster
- Test throttle response by gently pressing the accelerator pedal - response should be smooth and immediate
- Use an OBD-II scanner to verify no throttle position sensor codes are present
- Perform a test drive to confirm normal acceleration and no hesitation under load
