Parts for your 2009 Toyota Camry-Throttle position sensors

2009 Toyota Camry throttle-position-sensors

Technical sources from Toyota confirm the 2009 Camry (both 2.4L 2AZ‑FE and 3.5L 2GR‑FE) uses electronic throttle control (ETCS‑i) with throttle position sensing built into the throttle body. The Toyota New Car Features (ETCS‑i section), the 2009 Camry Electrical Wiring Diagram, and the Toyota Repair Manual describe dual throttle position sensors (redundant circuits) integrated with the throttle body and motor, plus dual accelerator pedal position sensors. So yes, a throttle position sensor is relevant and used on this model, it’s simply not a separate, adjustable bolt‑on sensor—it's part of the throttle body assembly.

The throttle position sensors on a 2009 Toyota Camry tell the engine control module exactly how far the throttle plate is open. With ETCS‑i, the ECU uses that signal—along with the pedal position—to command the throttle motor, manage airflow, fuel delivery, ignition timing and even shift behaviour. Because there are two TPS circuits inside the throttle body, the system can cross‑check signals for safety and throw a fault if something doesn’t add up.

There’s no separate TPS to tweak or replace on this Camry, it’s built into the throttle body. If the sensor goes out of spec or fails, the proper fix is replacing the throttle body assembly. After fitting a new unit, a scan tool is recommended to clear adaptations and run the ETCS initialisation. In many cases, the ECU will relearn at idle and with a short drive, but using a capable scan tool makes it quicker and tidier.

As part of routine servicing, it’s smart to keep the throttle body clean. Under the bonnet, remove the intake duct and gently clean the throttle bore and plate using throttle‑body‑safe cleaner—don’t force the plate open or soak the electronics. Check the connector for corrosion, make sure the loom isn’t chafed, and confirm the intake hose clamps are snug to avoid unmetered air sneaking in. If you’re chasing a drivability gremlin, a scan of live data (VTA/VTA2 throttle angle signals) and stored DTCs will tell you heaps.

• Common clues of TPS/throttle body issues: rough or hunting idle, hesitation, poor fuel economy, sudden lack of power (limp mode), and a Check Engine light—often with P0120‑P0124 or related throttle correlation codes.
• When replacement is needed, go quality—OE or reputable aftermarket—and have the relearn/initialisation performed for a smooth idle and crisp response.

Look after the throttle body and its sensors, and the Camry repays you with the easy, predictable throttle feel Aussies and Kiwis love on long kilometres.

Popular questions

Does the 2009 Camry have a replaceable TPS?
It has throttle position sensors, but they’re integrated into the throttle body with the motor. On both the 2.4 and 3.5, you replace the throttle body assembly if the sensor fails—there’s no separate bolt‑on TPS.

What are the signs the TPS is playing up on a 2009 Camry?
Expect erratic idle, hesitation on take‑off, sluggish throttle, or the car dropping into a reduced‑power mode. The Check Engine light will usually be on, and scan tools often show P0120‑P0124 or throttle correlation codes.

Do I need a relearn after replacing the throttle body?
Yes—best practice is to clear learned values and run the ETCS initialisation with a suitable scan tool. The ECU can relearn over a short idle and drive cycle, but a proper procedure delivers a quicker, more stable result.
