What is the location and function of the Throttle Position Sensor (TPS)?

The Throttle Position Sensor (TPS) on 2004 and earlier engines is attached to the firewall side of the throttle body. Problems with the TPS or motor can cause intermittent bursts of fuel from the injectors and an unstable idle because the PCM thinks the throttle is moving. The PCM is constantly comparing the driver's input from the accelerator pedal position sensor to the actual throttle position at the throttle body. A problem with the TPS circuits will set a diagnostic trouble code. To replace a defective TPS, disconnect the cable from the negative terminal of the battery. Disconnect the electrical connector at the TPS and remove the two mounting screws. Installation is the reverse of removal. On 2005 and later engines, the throttle body is operated by an electric throttle control motor instead of a cable. On these models, the TPS is part of the throttle motor assembly and cannot be replaced separately. If there are problems with the throttle control motor or the TPS, the complete throttle body must be replaced.

Pontiac Vibe Throttle Position Sensor

In addition, the Throttle Position Sensor (TPS) in Pontiac vehicles like that of Vibe is very important in controlling the air-fuel blend for combustion. The Throttle Position Sensor is a sensor that continuously sends signals to the fuel injection system about the current position of the throttle pedal; this way, the car's computer is able to constantly change the amount of fuel supplied according to the amount of power the engine is being asked to produce. This feedback loop occurs about tenth of a second whereby there is enhancing of acceleration, cruising, and deceleration. Pontiac Vibe models employ hall effect and magnetoresistive TPS as non-contact forms as compared to the potentiometric type that are metal contact types. The non-contact approach is more accurate in terms of performance and also improves on reliability because in sensing, it is based on the detection of change in the magnetic fields rather than resistance. Also, the wide open throttle (WOT) related accelerator pedal sensors enhance the effectiveness of the ETC system in the Vibe; and the integral of all of these, leads to raising the standard of the car's engine competence.
