Parts for your 2023 Toyota Camry-Throttle position sensors

2023 Toyota Camry Throttle Position Sensor (TPS)

Technical sources confirm the 2023 Toyota Camry does use a throttle position sensor — it’s built into the electronic throttle body. Toyota service literature for the XV70 Camry (Engine/Hybrid System – Fuel/Intake: Throttle Body with Motor Assembly) describes dual, redundant throttle position sensors integrated with the throttle control motor (ETCS‑i). Toyota’s OBD‑II fault listings for this model family also include TPS‑related DTCs (P0121–P0124), further confirming its presence. Toyota parts catalogues call the unit “Throttle Body with Motor Assembly”, noting the position sensors are internal and not serviced separately.

On the 2023 Camry’s 2.5‑litre petrol and hybrid variants, the TPS constantly reports the throttle plate angle to the engine control module. Working alongside the accelerator pedal position sensor, it lets the ECU manage torque, idle speed, cruise control and emissions with precision. The Camry uses dual TPS tracks for redundancy, if the two signals don’t agree, the ECU can drop into limp mode to protect the engine and driveline.

There’s no scheduled replacement for the TPS on this model. During routine servicing, it’s smart to check the throttle body connector for pin tension and any greenish corrosion, inspect the intake ducts for splits, and keep the air filter fresh. If drivability goes a bit pear‑shaped — erratic idle, flat spots, poor economy, cruise hunting — or the check‑engine lamp pops on with codes like P0121–P0124, a TPS issue could be in the mix.

Because the TPS is sealed inside the throttle body, the fix for a confirmed sensor fault is to replace the complete throttle body assembly. Use a new gasket, follow workshop torque specs, and perform the ETCS/idle relearn with a capable scan tool after fitting. Under the bonnet, don’t force the throttle plate by hand, if cleaning is needed for sticky deposits, use proper throttle‑body cleaner and a soft cloth with the ignition off. A gentle clean can sort minor sticking and prevent false TPS correlation faults.

• Common signs: MIL on with P0121–P0124, hesitation, stalling at idle, reduced‑power (limp) mode, rough take‑off.
• Good practice: inspect electrical connectors every service, keep the intake sealed tight, and do a relearn after battery disconnects or throttle work.
• Replacement tip: choose OE or quality equivalent throttles — the Camry’s ECU expects precise, matched dual‑track signals.

Professionals will also confirm live data shows sensible, matching TP1/TP2 readings that sweep smoothly from near‑closed to wide‑open. If they’re jumpy or disagree, it’s time for proper diagnosis — and possibly a new throttle body.

Popular questions

Does the 2023 Toyota Camry have a separate, replaceable TPS?
Yes. The 2023 Camry has throttle position sensing, but it’s built into the throttle body with motor assembly. Toyota designed it as a sealed, dual‑track unit, so the sensor isn’t sold on its own — the whole throttle body is replaced if the TPS is faulty.

How often should the TPS be replaced on a 2023 Camry?
There’s no routine interval. It’s a “replace on condition” item. If there are drivability symptoms or codes (P0121–P0124), get it diagnosed. Often, cleaning a sticky throttle and checking connectors sorts the issue, confirmed TPS faults require a new throttle body.

Do I need to recalibrate anything after throttle body replacement?
Yes. After fitting a new throttle body, the Camry needs an ETCS/idle relearn with a suitable scan tool. That lets the ECU learn the exact closed and open positions. Skipping this step can cause unstable idle or delayed throttle response.
