hello, I need some input
Hello,
I have a 6-speed 2005 RX8 with 140,440 miles.
Awhile ago I've had a code come on that's P0410 which is the Secondary Valve Air System. I've replaced the pump itself, and the CEL came back on but this time for the SSV valve bank 1, code was P2070. And that time the o2 sensor upstream CEL came on also. And since then I've replaced the o2 sensor a couple of days ago. After I replaced it that, I put some seafoam into the brake booster vacuum line. So now the 2070 CEL is off completely but the 0410 CEL is back on. But it doesn't initially come back on after I've cleared the check engine light with the OBD reader. The pump itself sounds like it's coming, but doesn't come on for long, maybe 10 seconds at most.
I'm thinking I might have to replace the SSV but I wanted to get some ideas before I start tearing into it.
Thanks

Sounds like the SSV is definitely due for a cleaning/replacement.
The air pump code coming back is a bit weird. Perhaps the air pump relay is unable to mantain contact?
It's also weird all these issues are occuring at the same time. Are the battery posts and grounding points clean?

P0410 has nothing to do with the SSV. It's the air pump and it runs during cold startup and produces a very lean condition by injecting air into the exhaust stream. The ECU monitors the front O2 sensor and throws a code if it doesn't look like air is being injected.
DTC P0410
Check that the air pump solenoid and vacuum actuator are working.

I've had this error a few times, if I remember correctly it has to do with the secondary valves being stuck open or shut in the intake manifold. Mine stick open giving the car a mean growl but it sounds like yours are stuck closed. I found that unless it's the 5th and 6th port actuators you can clean and free them up by hand. You can find the mechanical actuators on the midsection of the intake manifold, you can work them by hand and free them up sometimes. Otherwise the intake would have to be removed and any gunk cleaned from around them (or if your brave you could remove them).
