A throttle position sensor (TPS) is a sensor used to monitor the air intake of an engine. The Toyota 22R-E (and R-EC) engines use a "Linear" throttle position sensor. Precise sensor voltage adjustments are necessary when the new sensor is installed. Step 2. We've created informative articles that you can come back to again and again when you have questions or want to learn more! Non contact type TPS work on the principle of Hall effect or inductive sensors, or magnetoresistive technologies, wherein generally the magnet or inductive loop is the dynamic part which is mounted on the butterfly valve throttle spindle/shaft gear and the sensor & signal processing circuit board is mounted within the ETC gear box cover and is stationary. How a throttle position sensor works. Eventually, if this issue is left unattended it will put major stress on your motor and transmission mounts to the point where they will give out and will need replacement. For example, an extra "closed throttle position sensor" (CTPS) may be employed to indicate that the throttle is completely closed. The TPS monitors the position of the throttle valve, which regulates how much air is supplied to the engine. The function of a throttle position sensor is to monitor the position of throttle valve and report it back to the engine control unit. Step 1: Locate the sensor. The throttle position sensor in the 2005 Sorento is responsible for reading the positioning of the valve inside the throttle body and transmitting its reading to the electronic control unit via a change in output voltage. A failing Throttle Position Sensor (TPS), could be causing any or all of these problems. SELECT YOUR VEHICLE. More advanced forms of the sensor are also used. The (TPS) converts the (throttle valve) position into a proportional voltage signal. The TPS on the ETCS-i system has two contact arms and to resistors in one housing. Disconnect the negative battery cable and set it aside. Add your vehicle in Manage My … It can be located under the car hood, near the throttle mechanism.
