Have a po123 and po223,runs like crap,is there a difference in the accelerator pedal

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! The P0123 and P0223 codes you're seeing indicate issues with the accelerator pedal position sensor circuit. If you've replaced the pedal, it’s crucial to use the correct part designed for your 2005 BMW 525i, as variations in sensors can lead to compatibility issues and erratic performance. After replacing the accelerator pedal, you'll need to perform an adaptation reset, or "relearn," to allow the engine control module (ECM) to recognize the new pedal. This can typically be done using a diagnostic scanner that supports this function. If you don’t have access to a scanner, you can also try the following: 1. Turn the ignition on without starting the engine. 2. Press the accelerator pedal all the way down and hold it for about 10 seconds. 3. Release the pedal and turn the ignition off. This may help the computer adapt to the new pedal, but if the issue persists, it’s best to consult a professional for a thorough diagnostic.
