Question about 2005 Nissan Sentra
When I install the TPS the car work fine but in low the car star to go up in RPM and down, like from 1000 to 2500 constant. the part distributor told me that have to be calibrated. how, can you help
Did you buy a universal TPS? The one that you removed should have had to round screw holes. Did the new replacement have two round holes as well? If the two screw holes are slotted then you will need to adjust it. Without a scan-tool (to look at like data) it will take longer to adjust. Slide the TPS sensor into place and turn it until the spring and cam wheel starts to move. At this point STOP and tighten the screws. Start the car and test the operation of the sensor. You may need to fine tune the adjustment, be patient. Comparing the performance of the old sensor, to the new one. Is it better or worse then it was. Please write back with any new information or questions, good luck.

SOURCE: throttle position sensor
did your car have (ETS) electronic throttle control system
the TPSis a part of this system
but you can test it by using diagnoses scan tool to check the TPS value when press or depress the accelerator pad.
so you can tell us the NO. of DTC for example(P0122)

SOURCE: rpm going up and down
coolant temp switch can cause this. but add a can of SEAFOAM to fuel and change out the f filter again. the ETHANOL is causing unusual problems with these.

Throttle Position Sensor
The 3 wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the throttle blade.
The TPS is a 3wire variable resistor that provides the Powertrain Control Module (PCM) with an input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance (output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from .26 volts at minimum throttle opening (idle), to 4.49 volts at wide-open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This information is needed to assist in performing the following calculations:
Ignition timing advance Fuel injection pulse-width Idle (learned value or minimum TPS) Off-idle (0.06 volt) Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage) Deceleration fuel lean out Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage) A/C WOT cutoff (certain automatic transmissions only)
