To check the throttle sensor on a Cadillac Fleetwood, first ensure the vehicle is turned off and disconnect the battery. Next, locate the throttle position sensor (TPS) on the throttle body and use a multimeter to measure the voltage at the sensor's electrical connector while moving the throttle plate. The voltage should change smoothly as the throttle opens and closes. If the readings are inconsistent or out of the specified range, the sensor may need to be replaced.
It's part of the throttle body, entire unit must be replaced.
