Code P2176 Cadillac Description
The P2176 diagnostic trouble code (DTC) for Cadillac vehicles indicates that the minimum throttle position has not been learned by the engine control module (ECM). This means that the ECM has not been able to establish the minimum throttle position for the vehicle, which can lead to various performance issues. The throttle position is crucial for the proper operation of the engine, as it determines how much air enters the engine for combustion. Without knowing the minimum throttle position, the ECM may not be able to accurately control the engine's performance, leading to poor fuel efficiency, rough idling, hesitation during acceleration, and potentially stalling.

The Accelerator pedal was replaced yesterday, it drove fine no issues. This morning 1st attempt to start engine it made a ping/flicking noise on start but stalled out. 2nd attempt started as normal with very high rpm above 4500 for at least 10 -13 seconds idled down and sounds from trans area like a broken whistle then rpm started bouncing from low to high, placed in gear no surge, but still has pedal response. 3rd attempt start up it started but with constant rpm bounce high(3500) to low (1100) until it was shut down, no dieseling occurred. Now i'm guessing the throttle body blade must must have flipped or flickered or the new pedal caused a surge in TAC. I will try reinstalling old pedal accelerator to see if it gives a differrent response or needs to relearn. any help will do
