2004 Saturn Vue 3.5L V6 Engine Fault Code P1621: Symptoms and Causes

Model: 2004 Saturn VUE Fault Code: P1621 Posted: 2014-06-09 14:52

I recently encountered a fault code P1621 on my 2004 Saturn Vue with the 3.5L V6 engine. The vehicle suddenly lost all power while driving on the freeway, and the TCS (Traction Control System) warning light illuminated. This issue has caused significant concern, as it occurred during normal highway driving. I'm seeking information about what code P1621 means in this specific model, its potential causes, and whether it requires immediate attention or can be resolved with a diagnostic check.
