How to disconnect brown connecter on speed sensor transmission

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! The brown connector on the speed sensor of your 2006 Nissan Sentra can be a bit tricky to remove. It’s usually held in place by a small locking tab. First, gently press down on the tab (typically located on the top or side of the connector) to release it. While pressing the tab, try wiggling the connector back and forth as you pull. Sometimes connectors get stuck due to dirt or corrosion, so a little patience and maybe a small screwdriver to gently pry can help.
