Parts for your 2024 Toyota Camry-Throttle position sensors

2024 Toyota Camry throttle position sensor (TPS): what it does and how to look after it

Based on Toyota’s technical literature — the New Car Features (NCF) manual for the XV70 Camry and the Toyota Technical Information System (TIS) repair manual for 2018–2024 models — the 2024 Toyota Camry is fitted with a throttle position sensor. It’s part of Toyota’s Electronic Throttle Control System-intelligent (ETCS-i) and is integrated into the electronic throttle body rather than being a separate, serviceable sensor. Both petrol and hybrid 2024 Camry variants use this setup, with the engine control module (ECM) monitoring dual TPS tracks inside the throttle body alongside the accelerator pedal position sensor for redundancy and safety.

The TPS tells the ECM exactly how far the throttle plate is open, so fuelling, ignition timing, idle control and emissions systems can be managed with precision. In the 2024 Camry’s drive-by-wire arrangement, the ECM commands a throttle actuator motor, then cross-checks actual plate angle using two TPS circuits (“No.1” and “No.2”). If they don’t agree, the system can limit power to protect the engine and occupants.

There’s no scheduled replacement interval for the TPS on this model, and it normally lives a long life. As part of routine servicing, technicians will often inspect and clean the throttle body (especially the bore and plate edge) to prevent sticky throttle behaviour. Avoid spraying cleaner directly into the actuator housing or connector — the TPS is inside there — and use only appropriate throttle body cleaner. If battery power is disconnected or the throttle body is cleaned or replaced, a throttle/idle relearn may be required. Toyota’s Techstream or a capable scan tool can run the ETCS-i learning procedure, in many cases the ECM will also self-adapt after a short drive cycle.

• Common fault signs: erratic idle, poor throttle response, stalling on tip-in, cruise control drop-out, and the MIL on.
• Typical DTCs: P0120–P0124 (TPS circuit range/performance), P2135 (TPS correlation), P2101/P2111 (throttle actuator performance).

When a TPS fault is confirmed on a 2024 Camry, the fix is to replace the complete throttle body assembly (the TPS is not designed to be adjusted or replaced separately). Use a new gasket, check harness integrity, and torque fasteners to spec. After installation, perform the throttle learning routine and clear codes. Genuine or high-quality OEM-equivalent throttle bodies are recommended to ensure correct dual-track TPS readings and reliable ETCS-i operation. This approach keeps the Camry’s driveability crisp and its emissions right on the money for Aussie and Kiwi roads.

FAQs

Does the 2024 Camry actually have a throttle position sensor?
Yes. It’s built into the electronic throttle body as part of Toyota’s ETCS-i system. It isn’t a stand-alone sensor you can adjust, it’s read by the ECM as two redundant TPS signals to verify actual throttle plate angle on both petrol and hybrid models.

How often should the TPS be serviced or cleaned?
There’s no scheduled TPS service. Instead, keep the throttle body clean during regular maintenance (often every 60,000–100,000 kilometres, or when symptoms appear). Avoid flooding the actuator housing with cleaner — target the bore and plate, then allow a short relearn drive or use a scan tool to reset adaptations.

Can the TPS be calibrated without replacing parts?
The ECM will generally relearn after battery reconnection, throttle cleaning or replacement. For best results, use a capable scan tool (Toyota Techstream recommended) to run the ETCS-i/throttle position learning routine. If correlation faults persist, replacement of the complete throttle body may be required.
