Cadillac DeVille Problem Report
Cadillac DeVille Check Engine Light on Due to Failure of Secondary Air Injection Pump
Water may be drawn into the secondary air injection (AIR) pump causing the pump to fail and the Check Engine Light to illuminate. Our technicians tell us there is a kit available from General Motors to relocate the air intake for the pump which should prevent future damage from water intrusion.
The dealer told me secondaryair pump was bad. I found the air intake hose disconnected both ends. I installed new pump and intake cleared the code and the next cold start the light came back on. Now what? - 1bass

p0401 code is on

I replaced the pump 3 times , something else is causing the water to be injested into the pump - Visitor
Technical Service Bulletin 02-06-04-024G covers this problem. I was charged $249 for the pump and $250 for the labor. I will be returning to the dealership because it appears I was overcharged for labor. According to the TSB, the labor rate should be 0.9 hrs, which wouldn't approach the $250 I was charged.
The bottom of the TSB states:
Secondary AIR injection Pump and Hose Assembly - Replacement
