Problem on my 2001 Oldsmobile Aurora 3.5L.
Replaced secondary air injection pump with new GM part
and 2 wire connector to fix a P0410 code light is still on after being
cleared code.
Question 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 on the car.
The injection pump relay is ok .
JK:
That may be blown. Another common thing that can cause code P0410 is
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.
The PCM control the ground. Testing for vacuum out of solenoid must either be done at the
solenoid, or if doing at the diverter valves, both valves must be disconnected, and plug 1 off
while checking the other. Then plug the other, and check the first. If you just pull a hose off
one valve and check for vacuum, and the other valve is bad, the vacuum will all go to the bad
valve, and you will not get any at the valve you are checking. It does sound like the valves are
bad. They should hold vacuum. A way to test that is to jump the pump relay so it comes on,
engine at idle, use vacuum pump at 1 valve. You should hear a definite change in the sound of
the pump when vacuum applied then released if the valve is working.

| 10-25-10 where is these thing they call a pigtail |
| 10-25-10 Do you know where the AIR diverter valves is located on a 2001 Chevy Venture. |
| They are in similar locations as the engine above. But they are harder to find because being in the engine compartment of this type of minivan. |
| 11-23-10 I use a vacuum pump,and if the solenoid valve does not hold vacuum(the tiny plastic hose connection)then that was the problem on an Intrigue and Aurora. The passenger side by the reservoir in both cases.Dave |
| 1-2-11 is there any way that part wont allow the vehicle to turn over... |
| No. This has nothing to do with the car not cranking or starting. |
| 2-27-11 why does a car from calf. Have to pass Ill. Emissions test????????????????? |
| It does not matter what type of emissions the car has, it must pass the test. California emission is just a little different system that the federal emission all other states have. They are a little more stringent. |

| 7-26-11 I had one of those, where the pump filled with water. Another shop checked it and broke the pump in half. After the pump replacement, and the same code back again, I found one of the valves was stuck. After a re test of the system and a valve. Guess what? The light is back on. Whoops!Not fuse or lines either. |
| 11-13-11 How do you replace this valve? I have this same problem with my 2002 Oldsmobile Aurora and I can't seem to get the thing out. |
| 11-13-11 its tough, but you can get to the rear valve by coming at it through the bottom of the car. |
| 12-20-11 My 2001 Aurora pulled the P0410 Code. After getting the car scanned at the parts store and researching it enough to conclude that a shop should repair this for Me, I took it in. Since then this shop (a National Chain) has replaced the Sec. Air Pump three times. It keeps breaking inside where the clips or prongs that hold it together, break and it malfunctions within a day or two of the repair. The shop manager is at a loss as well as the mechanics. Not sure what to do and neither is the manager. They are covering the parts and labor to this point, but should I take the new replacement pump to a GM dealer and have them do the work while trying to get the original shop to pay for it. Is it worth the battle, I'm tired of leaving the car for the day and making arrangements for rides, imposing on other people. |
| 1-17-12 After installing the air pump the bottom cover must be firmly installed because it has an O-ring to seal the intake port of the pump to the intake hose attached to the cover. The clips are difficult to fasten also. I had to pry the cover up to the pump because I couldn't do it by my hands alone. |
