I've had my 2001 Jimmy in 3 different times in the last 3 years (warranty is about to expire). All 3 times the "Secondary Air Injection" was replaced, which included the hose, air pump and shield.
I'm curious if the dealer is just putting a band-aid on a bigger problem?
The code on the most recent visit was P0410. The dealers notes on my invoice says this time, they found water in air pump, and had to replace both the pump and valve and hose . They also found that the shield was missing as well.
I don't have the codes for the previous 2 times that it had to have the pump replaced.
Any advice would be greatly appreciated!
