Parts for your 2013 Toyota Rav4-Throttle position sensors

2013 Toyota RAV4 throttle-position-sensors (TPS)

Technical sources confirm the 2013 Toyota RAV4 does use throttle-position-sensors. Toyota’s New Car Features (NCF) for the XA40 RAV4 and the Toyota Repair Manual sections covering Engine Control and ETCS-i (Electronic Throttle Control System–intelligent) describe dual throttle position sensors integrated into the throttle body, as well as dual accelerator pedal position sensors. The factory diagnostic list for this model includes TPS-related DTCs (such as P0120–P0124 and P2135), which further shows the system is present and monitored on this vehicle.

On the 2013 RAV4, the throttle position sensors are built into the electronic throttle body. Their job is to tell the engine computer exactly how far the throttle plate is open, so it can manage fuel, spark, and idle speed smoothly. Because it’s a drive-by-wire setup, the ECM compares signals from the pedal position sensors and the throttle position sensors to keep everything safe and responsive. If the signals don’t agree, it’ll light the Check Engine lamp and may drop the vehicle into limp mode to protect the drivetrain.

Unlike older cable-throttle cars, the TPS here isn’t a separate, easily replaced unit. If the sensor fails or goes out of range, the fix is usually to replace the throttle body assembly and fit a new gasket. After replacement, the ECM will typically relearn the new position on its own after a short warm idle, though a scan tool can run an initialisation/reset if needed.

• Common signs of TPS trouble: erratic idle, hesitation, poor fuel economy, harsh shifts, and fault codes like P0120–P0124 or P2135.
• Basic servicing tip: clean the throttle bore and plate with proper throttle-body cleaner at service intervals (for many owners, every 60,000–100,000 kilometres works well). Don’t force the plate open by hand and don’t flood the electronics with solvent.
• Diagnostics: use a scan tool to view throttle angle and pedal position. Check connectors and grounds under the bonnet for corrosion or a loose fit before calling the throttle body.
• Replacement guidance: disconnect the battery if workshop practice requires, remove the intake ducting, unbolt the throttle body, replace the gasket, refit and tighten to manufacturer spec, then allow the engine to idle and relearn. Clear codes and road test.

This integrated setup keeps the RAV4’s throttle response tidy and reliable, provided the throttle body stays clean and the wiring remains sound.

FAQs

Where is the throttle position sensor on a 2013 RAV4?
The TPS is built into the electronic throttle body on the intake. There isn’t a separate bolt-on sensor like older models. The accelerator pedal also houses its own position sensors, which the ECM cross-checks with the throttle body sensors.

Does the TPS need regular servicing?
The TPS itself isn’t a scheduled service item, but keeping the throttle body clean and checking the harness and connector during routine servicing helps prevent signal glitches and idle issues. Many owners have the throttle body inspected and cleaned around every 60,000–100,000 kilometres.

How is the TPS reset after work is done?
After throttle body replacement or a battery disconnect, the ECM usually relearns throttle position automatically after a warm idle. A scan tool can perform a memory reset and throttle initialisation if needed. Avoid forcing the throttle plate by hand during any of this.
