Parts for your 2010 Toyota Camry-Throttle position sensors

2010 Toyota Camry throttle position sensor — is it used?

Yes — the 2010 Toyota Camry is fitted with throttle position sensors as part of Toyota’s ETCS‑i (Electronic Throttle Control System–intelligent). Technical sources including Toyota’s New Car Features (NCF) for the 2AZ‑FE/2AR‑FE/2GR‑FE engines and the 2010 Camry Repair Manual (Engine Control section) describe two throttle position sensor tracks inside the throttle body (often labelled VTA1/VTA2) plus dual accelerator pedal sensors for redundancy. The Repair Manual’s diagnostics for DTCs such as P0120–P0124 and P2135 further confirm the vehicle relies on these sensors for precise throttle plate feedback.

On this model, the throttle position sensors aren’t a separate, adjustable part like older cable-throttle setups. They’re integrated into the electronic throttle body, working with the throttle actuator motor to report the exact angle of the butterfly. That lets the engine ECU balance performance, emissions, and smooth drivability, especially when the A/C loads up or during cruise control. Toyota documents in NCF and the Repair Manual highlight the dual-sensor design as a safety and accuracy measure, if the signals disagree, the ECU can enter a protective mode to avoid unintended acceleration.

For servicing a 2010 Camry, the practical approach is to treat the throttle body and its built‑in sensors as one assembly. If there’s a check engine light with relevant codes (e.g., P0120–P0124, P0220, P2135), rough idle, hesitation, or limp-home behaviour, start with a clean of the throttle bore and plate using a suitable throttle body cleaner. Avoid forcing the plate by hand, and don’t flood the motor housing. After cleaning or battery disconnection, allow the ECU to relearn idle, Toyota procedures describe memory reset and idle learning (often completed automatically after a short drive once the engine is warm and accessories are off). A scan tool like Techstream can confirm both TPS tracks agree and sit within the expected voltages.

If the sensor readings are out of range or codes return, replacement typically means fitting a new throttle body with gasket, as Toyota supplies the sensor integrated. Some aftermarket options offer a standalone sensor, but alignment and reliability can be hit‑and‑miss. For most owners, a genuine or quality OE‑equivalent throttle body, installed with the battery isolated, clamp checks on the intake ducting, and a post-fit relearn, is the reliable fix backed by Toyota’s Repair Manual guidance.

• Symptoms to watch: MIL on, erratic idle, poor fuel economy, sluggish response, limp mode.
• Good practice: periodic throttle body cleaning, check for intake air leaks, scan for codes before parts swapping.

Popular questions

Does a 2010 Camry have a separate, adjustable TPS?
It uses an integrated dual-track TPS inside the electronic throttle body, so there’s no separate, adjustable sensor. Toyota’s NCF and Repair Manual specify the unit is factory‑set, diagnostics verify signals rather than “adjust TPS” like older models.

What are the signs the throttle position sensors are failing on a 2010 Camry?
Common signs include a check engine light with codes such as P0120–P0124 or P2135, hesitation on tip‑in, unstable idle, poor fuel use, or limp mode. If cleaning the throttle body and performing an idle relearn doesn’t sort it, the throttle body assembly may need replacement.

Can the TPS be replaced on its own, or is a full throttle body needed?
Toyota generally supplies the sensor as part of the throttle body assembly. While some aftermarket sensors exist, correct alignment and long‑term reliability can be tricky. Most workshops in Australia and New Zealand opt for a complete throttle body replacement to match the Repair Manual approach.
