Problem with my 2001 Oldsmobile Aurora 3.5L.
I replaced secondary air injection pump with new GM part
and 2 wire connector to fix a GM P0410 code check engine light is still on after being
cleared.
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:
That may be blown. Another common thing that can cause code P0410 is
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.
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.

The Secondary Air Injection (AIR) System reduces exhaust emissions following initial engine start up.
The powertrain control module (PCM) activates the AIR system by suppling a ground to the AIR pump
relay and AIR solenoid relay simultaneously. The AIR pump forces pressurized fresh air into the
pipes/hoses and past the check valve into the exhaust manifold, accelerating catalyst operation.

| 10-18-10 After having my transmission rebuilt I have this trouble code up po410,what could be the cause? |
Comments
| There could be many things that may have happened. They left something unplugged, blew a fuse, damaged the pump. The pump is located under the drivers side wheel well. |
| 4-18-10 have recently obtain the same fault codes on my 2001 Olds Intrigue it has 70,540 miles on it and i have two fault codes P0410 Air Injection System and P0742 TCC Stuck on could either of these faults be related? I have some knowledge on cars but having these two codes leaves me to believe a open or short circuit condition may be occurring as well as a circuit relay being defective if anyone has a clue i would prob get some sleep thanks |
| These codes are not related. The P0410 may be because of the problems stated above. P0742 is most likely internal to the trans. Solenoid or burned harness. |
| 7-23-11 where is AIR system for chevy venture located |

| 7-27-11 The system has many different parts. If you are looking for the air pump motor, it is located down by the transmission. There are also valves, pipes, solenoids etc. |
| 10-20-11 2001 Oldsmobile Intrique P0410 powered up air pump outside car ok all fuses ok where is pump relay and solenoid relay. |
| 1-3-12 Air system working goes through a check i have replaced both check valves vacuum lines ok cannot get it to pass the i/m for emission testing |
| If you mean the system is functioning, but the computer won't run and pass the I/M test. There are very specific parameters that must be met before ECM will run the test for that code. Highway driving with the A/C off will usually do it after a few days. |
| 1-12-12 I have a 2000 Olds Intrigue. Engine light is on. It usually takes a few moments to start and will often shut off after several seconds or a couple minutes. After that it runs very well. Any ideas? |
| Get the codes scanned. I bet you will find a code for the crank position sensor. Also check the fuel pressure regulator(FPR) for leaking. |
| 1-18-12 Sometimes when i start my 2001 Olds Aurora 3.5' the tranny wines and shifts very hard almost like it has a shift kit. i stop car and turn off ignition then start up again. Sometimes this fixes problem but sometimes i have to repeat several times before it fixes problem. Any ideas ? |
