Secondary air injection pump is making a loud humming noise at a cold start up. I pulled the error codes. P2441, p1445 and p1442. I contacted the Toyota dealership and the cost for the new pump is $2300. That is such a big expense for a 7 old truck and to have it repaired will be more than $3200. I believe that the design and construction of the part are flawed and replacement should be covered by Toyota. ## VIN failed ##.
