Parts for your 2007 Toyota Land cruiser-Throttle position sensors

2007 Toyota Land Cruiser throttle-position-sensors — what they do and when to service them

Technical sources confirm a throttle-position-sensor is fitted to the 2007 Toyota Land Cruiser. Toyota’s Land Cruiser 200 Series Repair Manual (Engine Control – ETCS-i) and the Electrical Wiring Diagram describe dual throttle position signals (VTA1/VTA2) built into the electronic throttle body on the petrol 2UZ‑FE. For the 1VD‑FTV V8 diesel, Toyota’s engine control documentation shows an electronically actuated intake throttle (often called the intake air control valve) with an integrated position sensor used for EGR and shutdown control. Earlier 100 Series models still on sale in 2007 also used ETCS‑i with an integrated TPS. In plain terms, every 2007 Land Cruiser variant uses a throttle-position-sensor, it’s just part of the throttle/intake valve assembly rather than a separate bolt-on switch.

The throttle-position-sensor tells the engine ECU exactly where the throttle plate sits. The ECU then lines that up with the accelerator pedal position, engine load, cruise control, traction control and transmission logic to keep the Land Cruiser smooth, torquey and compliant. On the diesel, the sensor also helps the ECU manage EGR flow and clean shutdown. Being dual-track, the ECU can cross-check both signals for safety.

On these models the TPS isn’t a standalone, adjustable piece. It’s sealed into the throttle body (petrol) or intake air control valve (diesel). If it fails or the signals don’t agree, replacement typically means swapping the assembly. Toyota’s manuals note common DTCs like P0120–P0124, P0220 and P2135 for correlation or range issues.

Good servicing habits for your 2007-toyota-land-cruiser throttle-position-sensors focus on cleanliness, data checks and correct setup:

• Every 60,000–100,000 km (sooner if you tour dusty tracks), inspect connectors and the intake duct for dust ingress. Clean the throttle bore with throttle-body-safe cleaner. Don’t soak the motor or sensor, and avoid forcing the butterfly by hand.
• If drivability is off—hesitation, erratic idle, limp mode or a flashing MIL—scan live data for VTA1/VTA2 and pedal position, they should rise smoothly and track together. Any flat spots or disagreement points to trouble.
• If replacement is needed, fit a quality assembly with a new gasket, torque fasteners to spec in the Toyota manual, and perform the throttle/idle learn procedure with a proper scan tool (or follow Toyota’s specified battery-off/initialisation steps). On diesels, run the intake throttle initialisation as directed.

Because the sensor is integral, cleaning and wiring checks often save the day. When the part really is gone, doing the relearn properly is what keeps the Cruiser idling sweet and shifting cleanly after the job.

Popular questions

Does a 2007 Toyota Land Cruiser have a throttle-position-sensor?
Yes. Toyota’s ETCS‑i system uses an integrated, dual-channel TPS within the throttle body (petrol 2UZ‑FE). The 1VD‑FTV diesel uses an electronically controlled intake throttle with its own position sensor. It’s not a separate adjustable unit.

What are the signs the TPS is failing on a 2007 Land Cruiser?
Tell-tales include a check engine light with codes like P0120–P0124 or P2135, poor throttle response, stalling or hunting idle, and sometimes limp mode. A scan tool will show VTA1/VTA2 signals that don’t track smoothly or don’t agree with pedal position.

Can the TPS be cleaned or adjusted on these models?
There’s no adjustment. You can clean the throttle bore to remove gum that upsets airflow, but don’t drown the electronic motor/sensor. If the sensor itself is faulty, replace the throttle body (petrol) or intake air control valve (diesel) and carry out the idle/throttle learn.
