Check Engine Light on Due to Failure of Secondary Air Injection Pump on Cadillac DeVille

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?

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.

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 It will not be published in the Labor Time Guide.

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
GM DEALER STATED PROBLEM WAS SECONDARY AIR PUMP.....WHICH WAS NOT UNDER THE GM VALUE GUARD WARRANTY.... COST $ 599 FOR PARTS AND LABOR........GM GUARANTEES REPAIR FOR 12 MONTHS OR 12,000 MILES, WHICHEVER COMES FIRST. 14 MONTHS LATER......CHECK ENGINE LIGHT CAME ON....INDICATING IT WAS THE SECONDARY AIRPIMP...

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.
pump replaced....fuse replaced....work done at dealer...told it was out of warranty, I had to pay for the repairs!!!
