You covered very well. If all parts test fine and P0410 still shows up, then it may be exhaust manifold air injection passage clogged by carbon which is the worst worst scenario !
@@BenzAddiction I'm just changing one of the valves and checking the lines I have the code p0410 and when I turn on the truck it smokes but the secondary pump doesn't work, I removed it and tested it and it works. Now one of the valves was not working and I had it installed tomorrow but I wanted to see if the secondary air pump cable had power but I never turned it on to check if it had power. Because of this code, is it normal for smoke to appear?
If you do the tests one by one it ticks off all of the components and hopefully you'll find the issue, smoke should not be related to air pump. This pump only injects air to exhaust. With valves stuck open you might get some exhaust gas in to the pump that can ruin it and produce extra noise.
Hello, I have a fault code 0694 M4/7 is not working correctly. The engine fan fails sporadically but comes on when you activate A/C. Do you recommend changing the motor fan or maybe it can be fixed? Regardss!
My pump burned out. I changed my pump, fuse, relay, solenoid and I checked the 2 vaccums they were clean. What could be wrong??. I did have an eval leak I fixed it by changing evap purge valve. But my p0410 code never goes away.
I did the same on my 09 c300. Replaced everything. Secondary air pump was also stuck . Problem was the check valves and my car only has 87k miles on it
Hi all, please test all the 5 components before taking your car to a shop or buying parts and save money on P0410 Secondary Air Pump...cheers Max.

Very good point, thank you mate.
How would you be able to clean those clogged passages? I think that is the case with my clk350.

Perfect video. Thank you!
You are welcome 😊
The cable that is connected to the secondary air pump does not have power. Don't you know why?
It only powers up for a min after start up usually. There is a relay that can go bad as well as fuse.

Needs diagnostic tools, take this seriously as you might end up with a blown engine.
@@BenzAddiction mmm, better to change it, new or second hand one?
High temperatures are coming in 2 months. Spain Summer.
What working temperature is appropriate for the engine?
So what fuse was missing for the camshaft or the secondary air pump?

@armendshaqiri7621 Clear the code, check to see if the valves open and close as they should.

@@brucewayne2773 Thanks for sharing 👍
What is the solenoid called? Secondary air intake solenoid?
Yes: Secondary air injection selenoid.
Thanks. Also, my OBD 2 scanner says “valve stuck open bank 2” is bank 2 the right side of the engine looking at it from the front of the car? Thanks
@@Wargasm54 Are you using a generic obd2 scanner?
@@BenzAddictionyes. Cheap scanner. Says “secondary air valve (bank 2) stuck open” code 0821
In this case, you are not getting specific data, consult with Google.
I have 07 Mercedes w221 I get p410 and it won’t start. Any idea?
The engine won't start or the air pump? If the engine won't start has nothing to do do with this code. Find another reason.
No codes come up at all
Video I’ve ever seen
