I have a 2004 olds bravada in which the service engine soon light came on again. the code is for the secondary air pump. the dealer fixed that malfunction 4 months ago,$660. Is this a common problem? what does it do and is it important to fix it again?
Hello and thank you for using JustAnswer. My name is XXXXX XXXXX X will do my best to help you with your Oldsmobile problem.The P0410 code for secondary air injection will falsely set when the O2 sensor is bad. There is a bulletin out on this malfunction. Replacing the O2 sensor will fix the problem and the cost will be roughly $110 to replace.
