P1121 BUICK Meaning

The Throttle Position (TP) sensor is a potentiometer. The TP sensor provides a voltage signal that changes relative to throttle blade angle. This signal voltage is one of the most important inputs used by the Powertrain Control Module (PCM). The TP sensor has a 5.0 volt reference circuit, a ground circuit, and a signal circuit.
TP sensor signal voltage should be approximately 0.6 volt at idle. TP sensor voltage should increase to over 4.0 volts at wide open throttle (WOT).
