Model: 2002 VW Cabrio Fault Code: P0121 Posted: 2017-07-11 18:26

I have a 2002 Volkswagen Cabrio displaying a P0121 diagnostic trouble code. The vehicle starts normally but runs roughly for a few seconds before settling into smooth operation throughout the day. I've already replaced the throttle position sensor assembly with a new unit, but the issue persists. I've thoroughly inspected all electrical connections and wiring harnesses, yet no faults have been identified. Any suggestions or troubleshooting steps for this specific P0121 code on a 2002 VW Cabrio? Please share insights based on reliable sources or known repair procedures.
