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

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.
