  Q: What is the purpose of the Throttle Position Sensor (TPS) on Nissan Maxima?

  A: A variable-resistance potentiometer called the Throttle Position Sensor (TPS) is attached to the throttle body's side, and it is connected to the throttle shaft. The TPS monitors the output voltage from TPS in order to determine fuel delivery based on throttle valve angle. An unstable idle and intermittent bursts of fuel may be caused by a broken or loose TPS. First, check for voltage supply and ground circuits from the PCM to the TPS before checking the TPS. Next, connect an ohmmeter across the TPS terminals and read off resistance with the gas pedal totally closed and progressively opened. As you increase the opening of the car's throttle control, you ought to observe an increase in resistance. Remove connector WOT/COT position switch connector and check for continuity at full throttle closed for no continuity as you open. If any readings are not correct, replace your Throttle Position Sensor (TPS). Disconnect battery cable, remove air intake duct then disconnect your oxygen sensor electrical connectors (wide open/closed throttle switch or WOT/COT switch). By removing screws that hold it in place, separate from throttle body a TPS can be detached. Put new one in right place and adjust till it is good enough for you.
