http://www.obd-codes.com/p0410Boy, a little research goes a long way! I copied the above link from this website that I found this morning while reviewing my work. If I had researched the code a little further I could have saved some time and a little money as you will see. Below is an excerpt from a post from me explaining some work I did on my son's car. You will read about my hypothesis on the chain of events that led to the failure of the air pump. If you check out the above link you will see that I am correct and if I had researched the code a little further initially I would have identified the valve as the
cause of the pump failure. Thankfully I only spent $20 for the pump. I put this together as a teaching tool for all of us.

I just put a new VSV for CCV on the 2001 Solara, the Toyota PN is 90910-12199 and it cost 57.34 before tax. I cleared the pending codes and will check in a couple of days to see if they reappear. I expect that it is fixed however because I tested the new solenoid and it operates as I thought it would, which confirms that the old one was in fact bad since it would not hold vacuum while energized and the new one does. BTW, this VSV is physically next to the VSV for EVAP, which is at the head of the system while the VSV for CCV is at the end of the system and is installed on the side of the air cleaner. It is not under the car, neither is the EVAP VSV.
Interestingly, my son's 2001 Saturn's MIL came on on the way back from the parts run to Toyota. I have been working on the Secondary Air Injection System for a while now, it is what us old-timers call the smog pump except now they are electric and controlled by the PCM. The original pump's bearings went bad so I replaced it with a used pump for $20 from a local salvage yard, a new pump is over $220 from Saturn and is a dealer only item. When the MIL came on again after 3 months I replaced the pump a second time with another used pump, again for $20 and decided that if this did not fix it I would bite the bullet and get a new pump next time. However, I think I jumped the gun because I noticed that there is water in the pump now when the MIL comes on but the motor runs fine and has a nice strong flow of air (after if blows about 8 ounces of water out). Since I had been on this tack of working on VSVs for the Solara, my eye was drawn to a VSV that opens and closes a valve that allows the pump to inject air into the exhaust. I tested it and it is in fact bad. I surmised that since this is stuck open and it is allowing moisture and exhaust gas to flow into the pump that is what ruined the first one. To my shame I didn't even test the second pump, when the same code came up and I saw that it was full of water I incorrectly assumed that it had gotten full of water at the salvage yard, I am not at all certain that it was in fact bad. So I will now change the VSV and see it that cures the MIL.
All that to say it is so nice to be able to apply what I learn to other situations and it is a good reminder to analyze, analyze, analyze, throwing parts at a broken vehicle is, in my opinion, and as the Brits say, "bad form!".
Cheerio!,
