  Q: What is the purpose and location of the Throttle Position Sensor (TPS) for Chevrolet C1500 and K1500?

  A: The throttle position sensor (TPS) is a variable potentiometer connected to the end of the throttle shaft on the throttle body. It monitors the output voltage to determine fuel delivery based on throttle valve angle. Intermittent bursts of fuel and an unstable idle are signs of a broken or loose TPS. The TPS is positioned on the side of the throttle body. Loose terminations or broken wires should be checked. Before checking the TPS, ensure that there is correct functioning of the voltage supply and ground circuits. Disconnecting the electrical connector will enable you to check its voltage, which should be approximately 5.0 volts. If it's wrong then you must check your wiring. To test TPS operation, reconnect your connector and then back probe the dark blue wire terminal. Gradually open the throttle and observe whether voltage increases smoothly or not? If it does not, replace it with correct one because faulty ones can cause incorrect readings when testing for fuel injection problems in your car's engine system such as too much or too little fuel being delivered into cylinder at any given point in time; this may result in poor performance levels during acceleration process by reducing power output produced from motors while driving along highways, streets etc., which will ultimately affect overall speed achieved at any moment under different conditions depending upon circumstances surrounding its usage within community members living area around us today so make sure everything goes well before something bad happens again due certain reasons whatsoever throughout entire life span till Death do part away eventually without warning sometimes!) To replace your Throttle Position Sensor (TPS), access it by removing what needs to be removed first. At present you can disconnect electrical connector and remove mounting screws also. Remember to put a new O-ring in place on top before tightening down screws, as well as making sure that TPS aligns properly with throttle shaft prior tightening up all bolts.
