Secondary Air System Followed By Serpentine Belt Tension Pulley
After 2 check valve replacements and another $140 worth of diagnostics and "cleaning", I became curious about the exposed wires for the secondary air solenoid plug, so I began my research in earnest. I downloaded a wire harness diagram with the colors indicated, and followed that up with a quick perusal of Autozone solenoid electrical connectors. Some bonehead swapped the plugs for the secondary air and intake air solenoids probably during a timing belt swap about 10,000 miles and one owner ago. I swapped them back correctly, and the P0411 code persisted for 2 weeks, before I had to clear it manually. Two days and 5 starts later, I took it to the emissions station and it passed with flying colors.
The very next day, today to be exact, junior borrows the car to drive to his pal's house, and the plastic serpentine tension pulley explodes, shredding the belt. He managed to limp into a nearby shopping center. It won't be my first parking lot repair, and I sincerely doubt it will be my last. I would like to thank my dad for "encouraging" me to help out those many years ago, may he rest in peace. The Vista Cruiser with its 455 was an excellent classroom.
The 2001 wiring diagram is attached. My problem was solved on page 14. Enjoy.

Re: Secondary Air System Followed By Serpentine Belt Tension Pulley
When my serpentine belt died I had the tensioner replaced. Since the cam timing belt tensioner was a recall item I didn't trust the serpentine tensioner. Why would they build one better than the other? No facts to support this, just my innate paranoia.
