Parts for your 2007 Toyota Camry-Throttle position sensors

2007 Toyota Camry throttle position sensors (TPS): what they do and how to look after them

Based on technical sources—the Toyota New Car Features (NCF) guide for the 2007 Camry and the factory Repair Manual sections covering the EFI and ETCS‑i systems for the 2AZ‑FE and 2GR‑FE engines—the 2007 Toyota Camry is fitted with throttle position sensors. They’re built into the electronic throttle body (ETCS‑i) as a pair of redundant sensors, rather than being a separate, adjustable unit like older cable-throttle setups. The Toyota Electrical Wiring Diagram (EWD) for this model also shows dual TP sensor circuits feeding the ECM.

On a 2007 Camry, the throttle position sensors tell the engine computer exactly where the throttle plate is, moment by moment. Because the car uses drive‑by‑wire (ETCS‑i), the ECM commands a small electric motor to open the throttle while constantly cross‑checking the dual TPS signals to keep things smooth, safe, and efficient. This helps deliver crisp throttle response, stable idle, better fuel economy and reduced emissions—especially when paired with the dual accelerator pedal position sensors.

As part of routine servicing, it’s smart to keep the throttle body clean—dusty intake air and oily vapour can gum up the plate and upset TPS readings. If the throttle body is removed for cleaning, avoid forcing the plate by hand and don’t flood the shaft with cleaner. After any significant work, a throttle relearn (idle learn) may be needed, a scan tool or a proper drive cycle usually sorts it.

Unlike older Toyotas, the 2007 Camry’s TPS is integrated into the throttle body and isn’t separately serviceable. If the sensor fails, the fix is typically a complete throttle body replacement, followed by clearing ECU adaptations and confirming the idle learn. Signs that point to TPS/throttle body trouble include:

• Erratic idle, stalling, or poor off‑the‑line response
• Surging on light throttle or a dead spot as the pedal is pressed
• Warning lights and fault codes such as P0121–P0123 or P2135
• “Limp” mode with limited power

Before replacing anything, a proper diagnosis is worth its weight in gold: check wiring/connector condition under the bonnet, ensure the throttle plate isn’t sticking, and confirm sensor data with a scan tool (both TPS signals should track smoothly and agree with each other). If replacement is needed, use quality parts, fit a new gasket, torque the bolts correctly, and perform the throttle/idle relearn so the ECM knows the new unit’s exact closed and open positions. That way, the Camry keeps running sweetly for many more kilometres.

Popular questions about 2007 Toyota Camry throttle position sensors

Does the 2007 Camry have a separate TPS or is it part of the throttle body?
It’s part of the electronic throttle body. Toyota uses ETCS‑i on this model, with dual throttle position sensors built in for redundancy. If the sensor fails, the usual repair is to replace the whole throttle body rather than just the sensor.

What are the common symptoms of a failing TPS on a 2007 Camry?
Expect rough or unstable idle, hesitation, surging, or sudden loss of power. The check engine light often comes on with codes like P0121–P0123 or P2135. A scan tool will show inconsistent or mismatched TPS signals when the throttle is opened and closed.

After replacing the throttle body, does the 2007 Camry need calibration?
Yes. Clearing ECU adaptations and performing an idle/throttle relearn is recommended. Many scan tools can command this, otherwise, a correct drive cycle will let the ECM relearn the new throttle body’s closed and open positions for stable idle and smooth response.
