The throttle position sensor (TPS) in a Toyota RAV4 is a crucial component that monitors the position of the throttle valve, which affects engine performance and responsiveness. Knowing its location is essential for maintenance and troubleshooting.

Throttle Position Sensor Location

The throttle position sensor is typically located on the throttle body of the Toyota RAV4. Here are some specifics regarding its placement:

  • Position: The TPS is situated opposite the spring for the throttle cable, making it accessible for maintenance.

  • Accessing the Sensor: To reach the TPS, you often need to remove any surrounding components that may obstruct access, such as air intake ducts or electrical connectors.

  • Removal Process: The sensor can be removed by disconnecting its electrical connector and unscrewing it from its mounting point. It usually requires a couple of screws to secure it in place.
