Is the second air pump of Saturn 2002 must run all the time when the engine is running?

The second air pump on a 2002 Saturn, often referred to as the secondary air injection system, is designed to operate during specific conditions to help reduce emissions. It typically runs when the engine is cold and during certain periods after startup to aid in emissions control. If the pump is running continuously while the engine is operating, it may indicate a malfunction or issue with the system. It's best to consult a mechanic or refer to the vehicle's service manual for accurate diagnosis and operation guidelines.
