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.

Water has filled the air pump and it has been replaced 3 times. It now has filled for the 4th time and no one seems to be able to tell me where the water is coming from.The pumps are Delco pumps I'm ready to trade the car.
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?
p0401 code is on pump is bad replaced still light came on

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: Labor Operation J6052 Secondary AIR injection Pump and Hose Assembly - Replacement Labor Time 0.9 hr* *This is a unique labor operation for bulletin use only. It will not be published in the Labor Time Guide.

I've also replaced the air pump, including the intake relocation. The light came back on, there was water in the pump, again. I think it may be a faulty secondary air injection valve (check valve) allowing water to get sucked into the system.

Spent $800 to replace secondary air injection pump (that including the relocation kit) for my 2005 DeVille w/105k. 16 months later same problem as before, water has entered the pump and it whines like a banshee. Anybody else experienced this?

it first started with the secondary air pump winding up very fast so changed it and the next pump did the same thing one year later. The third pump froze up 6 months later had water in it. On the fourth one now only a month yet. Need the use the retrofit inlet kit I guess. Not wanting to spend the extra money for the retrofit.
Fan turns non 30 sec at cold start then would screech know fan does not turn on screeched about 2 months

Check engine light comes on
loud whining noise that last about a minute, dealer said air injection pump failure, parts and labor 747.00.
Advanced Auto Diagnosed it. 7 Times to Deluxe Auto before they actually repaired it and didn't just reset the computer. They are the absolute worst to do business with.
