How To Set Throttle Position Sensor Ajustment for idle control - See How

In the video we show you how to adjust the Nissan Hitachi Throttle Position Sensor(TPS) on the Nissan Frontier Vg33e(V6) Engine. By using a Multi-Volt meter we explain all the process to make a proper adjustment to the TPS for recommended idle speed.HOW TO ADJUST THE THROTTLE POSITION SENSOR?. HOW TO MAKE CHANGES IN ENGINE IDLE?.HOW TO REPLACE TPS SENSOR?.WHAT IS A POTENTIOMETER?.The throttle position sensor responds to the acceleration pedal movement. This sensor is a kind of POTENTIOMETER which transforms the throttle position into output voltage, and emits the voltage signal to the ECM. In addition, the sensor detect the opening and closing speed of the throttle valve and feeds the voltage signal to the ECM. Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine such as fuel cut. On the other hand, the "Wide Open and Close Throttle position switch", Which is build into the throttle position sensor unit, is not used for engine control.DTC(code) P01231 is Throttle Position Sensor circuit range/performance problem - (A) A High voltage from the sensor is send to ECM under light load driving condition - Possible cause is Harness or Connector(TP) sensor circuit is open or shorted, or TPS, or Fuel injector, or Camshaft position sensor, or Mass air flow sensor.DTC(code) - P0121 is Throttle position sensor circuit range/performance problem - (B) A low voltage from the sensor is sent to ECM under Heavy load driving condition - Possible cause is Harness or connector(The Throttle Position sensor circuit is open or shorted.), or Intake air leak, or Throttle Position sensor.
