Parts for your 2015 Toyota Camry-Throttle position sensors

2015 Toyota Camry Throttle Position Sensor (TPS)

Based on Toyota technical sources — including the Toyota TIS repair manual and EWD for the 2015 Camry (2AR-FE 2.5L, 2GR-FE 3.5L, and 2AR-FXE hybrid) and the Toyota electronic parts catalogue — the 2015 Camry does use throttle-position sensing. It’s built into the electronic throttle body as dual TPS circuits (often labelled VTA1/VTA2) as part of Toyota’s ETCS-i system. Fault coverage in the manual includes DTCs such as P0120–P0124 and P2135, confirming the sensor’s presence and function. The TPS is not a separate bolt-on item, it’s integral to the throttle body assembly.

On this Camry, the throttle position sensors tell the engine control module exactly how far the throttle plate is open. Working alongside the accelerator pedal position sensors, they let the ECU control the throttle motor smoothly and safely. That means better drivability, improved fuel economy and emissions, and limp-home protection if signals don’t agree. Because Toyota builds the TPS into the throttle body, there’s no adjustment and typically no separate replacement of the sensor — if it fails, the usual fix is a complete throttle body assembly.

There’s no scheduled TPS maintenance, but a tidy throttle body helps the sensors read cleanly. Under the bonnet, a light clean of the throttle bore and blade every 60,000–100,000 kilometres can prevent sticky idle behaviour. Use proper throttle body cleaner, don’t flood the motor housing, and never force the blade open against its stop. A new throttle body gasket is wise if it’s removed.

If the Camry flags a TPS-related code or goes into limp mode, checks start with the basics: battery health, good grounds, and a solid 5‑volt reference. Inspect the throttle body connector for corrosion or a loose fit, and make sure the harness isn’t chafed where it crosses the intake. If readings from VTA1 and VTA2 don’t track smoothly and agree within spec (as the wiring diagram shows), replacement of the throttle body is the go. After refit, clear codes and perform an idle/throttle learn. Many scan tools can run an ETCS reset, otherwise, a short drive with varied throttle usually lets the ECU relearn. Genuine or high-quality aftermarket throttle bodies tend to provide the most reliable result, and the job typically takes about an hour with basic spanners and a torque wrench.

• Common signs: erratic idle, hesitation, poor fuel economy, harsh shifting, or a Check Engine Light with P0120–P0124/P2135.
• Service tips: don’t adjust the stop screw, keep connectors clean and latched, replace the gasket if the body comes off.

Popular questions

Does a 2015 Camry have a separate TPS I can swap?
Not on most models. The TPS is integrated into the electronic throttle body along with the motor. Toyota’s parts catalogue lists the assembly as one unit, so if the sensor fails or the signals disagree, the usual repair is to replace the throttle body. Some aftermarket options claim separate sensors, but they’re hit-and-miss and often don’t match factory specs or durability.

Do I need to recalibrate the TPS after cleaning or replacing the throttle body?
After cleaning, the ECU typically relearns idle over a short drive. After replacing the throttle body, it’s best practice to perform an ETCS/throttle learn with a scan tool and then take the car for a varied drive cycle. Clear any stored DTCs, check for stable idle, and verify there’s no throttle lag or hunting.

What usually causes TPS codes on a 2015 Camry?
Common culprits include a dirty throttle bore creating inconsistent airflow versus position, connector corrosion, wiring damage near the intake, low 5‑volt reference, or internal wear of the throttle body’s dual sensor tracks. Less often, water ingress or incorrect aftermarket parts trigger mismatch codes like P2135.
