1997 Nissan/Datsun Altima 2.4L SFI DOHC 4cyl: the Throttle Position (TP) sensor
is a potentiometer. It is mounted on the side of the throttle body and
is connected to the throttle plate shaft. The sensor monitors throttle
plate movement and position, and transmits an appropriate electrical
signal to the ECM. These signals are used by the ECM to adjust the
air/fuel mixture and spark timing according to engine load. The TP
sensor is adjustable on some models.
Automatic
transaxle/transmission TP sensors contain position switches. These
switches provide a signal to the ECM when the engine is at idle and wide
open throttle.
Hope helps (remmeber to rate and comment this).
Also, to answer your question, TPS stands for Throttle Position Sensor. It is located in the same place on all cars...On the throttle body. No, it is not likely to cause the symptoms you are describing.
