Hi all,

Have a new P0410 code off the OBD2 tester. Just replaced the sensor from the P0108 code check engine light was off for a week and the new code popped up. Now have black duckt tape covering the darn check engine light.

I gather through the net that the P0410 is a secondary air pump failure code.
How do I fix this the easiest, cheapest way please??
They are having a spring dust off in Yipsilanti next week, I can go down n ask fellow Volvo owners /network in finding a nice mechanic who will fix for me?

 

That code indicates either faulty signal, or a leak. The code actually references two codes in my system. If it's the signal, you can try checking the contacts and the relay. If it's a leak, "a muffled sucking sound can be heard from the engine compartment when the engine is idling." You can try checking the hoses and see if there is a crack or loose connection. Not really anything else listed in the repair section.

 

I think 8 of 10 times it's a leak. So, look at your vacuum lines real good, air hoses, etc. You maybe should also change the seal on your fuel cap and make sure you click that thing 3 or 4 times when putting the gas cap back on.

 

I removed my air pump and hoses, and capped them off. Left the air pump control relay, and no more troubles. The ECU has no idea that the system is nonexistant, save for the control relay.

 

Wow, a lot of cars don't have air pumps. Mine does not. Not sure why they put the system in some and left it out of others. Like they were experimenting.

 

Thanks guys... will try that check for vacumn leaks I mean... yes thanks to Volvo's experimenting costs us money to get their experiments to factory specs...lol

 

Did that kinda sorta. Put a new locking fuel cap on considering fuel prices in MI are jumping between $3.95 (one week) to $4.15 the next and back.

 

Try paying $6.50 US a gallon

 

I think it all but impossible to steal gas out of post 90's Volvo. You also want to make sure the cap is a Volvo cap. Others will not seal the system properly. I tried buying a new after market cap once and it caused the code, not to mention breaking in just 2 weeks.
