How to service and repair the Throttle Position Sensor on Chevrolet Metro?

Begin Throttle Position Sensor service by first eliminating the bolt that connects the air inlet duct resonator to the air intake box. First loosen the hose clamp on the resonator pipe so you can swing the pipe aside. Disconnect the electrical connector which serves the throttle position (TP) sensor before removing two screws to detach the ip sensor from the Throttle Body. The tp sensor setup on the Throttle Body requires the tp sensor upper screw hole placement slightly ahead of the Throttle Body's hole for proper engagement between the throttle lever tab and tp sensor movement. Rotate the tp sensor rearward to align the screw holes and install the 2 screws, tightening them to 2.0 n.m (18 lb in). The tp sensor electrical connector connects first followed by attaching the resonator pipe to the air intake box and fitting it with one bolt. Complete this operation by tightening the resonator's hose clamp.

Chevrolet Metro Throttle Position Sensor (TPS) is one of the most important components that assist in the supply of adequate air-fuel blend for proper burning. Being an essential component of the fuel injection system, TPS controls the amount of power being requested by transmitting signals of the position of the throttle pedal to the computer that regulates the fuel injection. This process takes place many times per second, and as such, there are no noticeable shaking while accelerating or decelerating. Chevrolet Metro models employ both the matured potentiometric TPS and the novel non-contact forms for example the Hall effect. The latter is more reliable than the former because there is no contact that would cause wear and tear hence enhancing its performance. Also fitted is the Closed Throttle Position Sensor (CTPS), which helps in determining to the engine the status of the fully closed throttle. In general, the changes made to the Throttle Position Sensor in Chevrolet Metro vehicles are representative of progress in technology designed to optimize an automobile engine.
