Problem with my 2001 Oldsmobile Aurora 3.5L
replaced secondary air injection pump with new GM part
and 2 wire connector to fix a PO410 code light is still on after being
cleared
comments = Dear JK: Wondering if there is some fuse or wire that could
be blown from the air injection pump connector being melted? I have
seen this on one other occasion and was not able to repair the problem.
The injection pump relay is ok
JK:
Yes, there is a 50 amp maxi fuse in the underhood fuse block.
That may be blown. Another common thing that can cause that code is
one or both of the AIR diverter valves that are vacuum controlled by the bypass valve
solenoid. That solenoid is powered by the IGN 1 fuse.
These two valves get stuck and do not allow the air from the pump to enter the exhaust.
The valves are silver, and have small tubes running into the exhaust manifolds. They
have 1 vacuum hose on them. One is above the belt, near the firewall, the other is near
the dr. side of the front valve cover. Use a vacuum pump to see if the valves hold
vacuum after making sure the solenoid is supplying vacuum when the AIR pump turns on.
