What is the Throttle Position Sensor and how do you diagnose and replace it on 1997 through 2001 Toyota Solara?

Locate the Throttle Position Sensor (TPS) on the end of the throttle shaft to check it. Verify the reference voltage located on the Powertrain Control Module (PCM). Disconnect the TPS electrical connector and touch the probes of a volt meter to terminal number 1 and ground. With the ignition key turned ON, it should be 4.5 to 5.5 volts. If it is out of range or if there is no reference voltage, have the PCM checked. Next, check the TPS signal voltage. Reconnect the electrical connector to the TPS. Back pin terminals 2 and 3 of the TPS electrical connector. With the ignition key turned to ON and the throttle fully closed, the voltage should read 0.3 to 1.0 volts. Then, slowly open the throttle to increase it. If the indicated readings are below or above the specified range, replace the TPS. To remove it, make sure the ignition key is in the OFF position. Disconnect the electrical connector from the TPS. Remove the screws that retain the TPS to the throttle body and remove the TPS. Installation is the reverse of removal.

Toyota Solara Throttle Position Sensor

The Throttle Position Sensor (TPS) of the Toyota Solara has the function of controlling the flow of the mixture of air and fuel required for combustion. The Throttle Position Sensor constantly measures the position of the throttle plate, and relays signals to the fuel injection system so the vehicle's computer can regulate the fuel delivery in accordance to the power request of the engine. This kind of feedback happens many times per second, and it allows for perfect acceleration, cruising, and deceleration. Cutting edge non-contact Throttle Position Sensor types are deployed in Toyota Solara models, which include the Hall effect and magnetoresistive types, which are different from potentiometric types that make use of contact. These non-contacting sensors give more reliability and power by changing magnetic fields instead of opposition based sensors. Also, other Throttle Pedal Sensors such as the Wide Open Throttle (WOT) act with TPS to increase engine efficiency in electronic throttle control systems.
