Parts for your 2007 Toyota Aurion-Throttle position sensors

2007 Toyota Aurion throttle-position-sensors (TPS)

Technical sources confirm the 2007 Toyota Aurion is fitted with throttle-position-sensors. Toyota’s New Car Features for the 2GR‑FE, the Repair Manual (Engine Control – ETCS‑i), and the Electrical Wiring Diagram for Aurion/Camry XV40 all show an electronic throttle body with a throttle motor and dual throttle-position-sensors (often referenced as VTA1/VTA2) integrated into the assembly. The factory diagnostic sections listing DTCs such as P0120–P0124 and P2135 further support that TPS inputs are monitored on this model.

The Aurion’s throttle-position-sensors play a vital role in how the car drives. Because the 2GR‑FE uses Toyota’s ETCS‑i (drive-by-wire), the ECU relies on paired TPS signals to know exactly where the throttle plate sits. That lets it manage idle stability, smooth take-offs, cruise control and fuel economy. The dual-sensor setup adds redundancy for safety and accuracy, so if the two signals don’t agree, the system can jump into a protective limp mode to keep things safe.

On this model, the TPS is built into the throttle body, so it’s usually not serviced separately. If a sensor fails, the normal repair is to replace the throttle body assembly. A genuine-quality unit, a fresh gasket, and a proper relearn are the keys to a tidy job. After fitting, clear codes and carry out a throttle/idle learn with a Toyota-compatible scan tool (Techstream or equivalent). Without a scan tool, the ECU will generally relearn over a short mixed drive, but a formal initialisation is best practice.

There’s still smart maintenance to extend the life of the throttle-position-sensors. Keep the throttle bore clean: remove the intake duct and gently clean the throttle plate and bore with throttle-safe cleaner, avoiding soaking the shaft or electronics. Check the connector for moisture or corrosion, and ensure the engine earths are sound. If the Check Engine light pops on with rough idle, delayed throttle response, or “limp” behaviour, scan for codes like P0120, P0122, P0123 or P2135 and inspect the wiring before condemning the assembly.

For most workshops, replacement time is modest. Expect to top up or bleed coolant if the throttle body is coolant-heated, fit the new gasket, torque fasteners evenly, then perform the relearn and a quick road test to confirm fine throttle control and smooth idle.

• Recommended service habit: inspect and clean the throttle body every 60,000–100,000 km
• Always use throttle-body-safe cleaner and avoid over-spraying the sensor area
• After any work, perform an idle/throttle learn and clear stored codes

Popular questions about 2007 Toyota Aurion throttle-position-sensors

Is the TPS on a 2007 Aurion replaceable on its own?
The throttle-position-sensors are integrated into the electronic throttle body on the Aurion. Toyota’s manuals specify replacing the throttle body assembly if the TPS is faulty. While some aftermarket parts claim separate TPS compatibility, most reliable repairs use the complete assembly to match factory specs and ensure correct calibration.

What fault codes point to TPS issues on a 2007 Aurion?
Common TPS-related codes include P0120, P0122, P0123 and P2135 (correlation between the dual TPS signals). You may also see throttle actuator codes if the motor or power supply is involved. If these appear with limp mode, poor throttle response, or “TRC OFF” lights, check the connector and wiring first, then test the throttle body assembly.

Does the TPS need calibration after replacement or cleaning?
Yes, after throttle body replacement—and often after a thorough clean—an idle/throttle learn should be performed. Using a Toyota-capable scan tool is the tidy way to initialise the ETCS‑i. If that’s not available, the ECU will usually relearn over a short drive cycle, but a proper initialisation delivers quicker, more stable results.
