Parts for your 2022 Toyota Camry-Throttle position sensors

2022 Toyota Camry throttle-position-sensor (TPS)

Based on Toyota’s own technical literature — the Toyota Repair Manual (TIS) for the 2018–2022 XV70 Camry range, the New Car Features (NCF) manual describing ETCS‑i (Electronic Throttle Control), and the Toyota wiring diagrams (EWD) showing VTA1/VTA2 throttle angle signals — the 2022 Toyota Camry absolutely uses throttle-position sensors. They’re built into the electronic throttle body as dual, redundant sensors and are not serviced separately from the throttle body assembly. The accelerator pedal also has its own position sensor for redundancy and fail‑safe.

On a 2022 Camry, the throttle-position sensors tell the engine control module exactly how far the throttle plate is open. That live data is used to manage fuelling, ignition timing, idle speed control, transmission shift strategy, cruise control, and traction/stability systems. Because Toyota’s ETCS‑i is fully electronic, the TPS pair inside the throttle body provides two matching-but-inverse signals, so the ECU can constantly cross‑check for accuracy and trigger a limp‑home mode if readings don’t agree.

There isn’t a scheduled replacement interval for the TPS on this model, and owners typically won’t touch the sensors directly because they’re integrated. What helps is keeping the throttle body clean — especially for cars doing lots of short trips or driving in dusty conditions. During servicing it’s smart to:

• Inspect the throttle body for carbon build‑up and gently clean the bore and plate using throttle‑body safe cleaner (avoid soaking the sensor area).
• Check for air leaks at the throttle body gasket and intake ducting.
• Scan for fault codes such as P0120–P0124 or P2135 and review live data for VTA1/VTA2 agreement.

Typical signs it’s time for attention include a Check Engine light, erratic idle, sluggish or jumpy throttle response, poor fuel economy, or the car dropping into reduced‑power mode. If the TPS circuitry fails or readings won’t align, the fix on a 2022 Camry is to replace the complete throttle body assembly. The sensor isn’t designed to be removed or adjusted on its own.

After fitting a new throttle body, a technician should renew the gasket, torque the fasteners to spec, clear codes, and perform the appropriate ETCS‑i/throttle learning with a scan tool so the ECU can relearn the fully closed and fully open positions. A short drive cycle often finalises the idle learn. Done right, the result is smooth, predictable throttle feel and stable idle for thousands of kilometres.

Popular questions about 2022 Toyota Camry throttle-position-sensors

Does the 2022 Camry have a separate TPS I can swap out?

No. On all 2022 Camry petrol and hybrid variants, the throttle-position sensors are built into the electronic throttle body. If the TPS circuitry is faulty, the correct repair is to replace the throttle body assembly and carry out the ETCS‑i relearn with a scan tool.

Can the TPS be calibrated without a scan tool?

The ECU will do some self‑learning after battery disconnect or cleaning, but proper throttle position and idle learning is best performed with a capable scan tool. That ensures the ECU stores the correct zero and full‑open reference points, preventing high or unstable idle and touchy throttle response.

What fault codes point to a TPS issue on a 2022 Camry?

Common DTCs include P0120–P0124 (TPS circuit range/performance, high/low, or intermittent) and P2135 (throttle/pedal position sensor voltage correlation). These merit a wiring check, throttle body inspection, and, if confirmed, replacement of the throttle body assembly followed by calibration.
