This engine is from up north take it to the car wash and get that engine washed its a losing battle to keep it in to condition if its salted over and rusted.

Is the air pump supposed to turn off after about 10 seconds?

hi i took the hose from the switch air pump solenoide to the air pump valve for vaccum,the car runs nicely now,the code still on but iam looking to the air pump solenoid switch part,after change that the code should be gone thanks richpin

@methunshow When you test the air pump its not enough to just confirm rotation do a scanner analysis with an amp clamp to asses the pumps viability. It takes a strong pump to irrigate the exhaust manifold against exhaust pressures. Check the diverter valve for vacuum continuity and mechanical actuation all the way back to the intake manifold. Do a frequency and voltage check of your O2 pre CAT sensors. Check with mercedes for updates in your Engine Control Module [ECM] software

@richpin06a Rich, No air flow at the exhaust manifold port where the tube attaches with the engine running. I'll have to pull the exhaust manifold. I also had a P0401 and found lots of gunk in the intake port to the EGR valve. It was like tar That's nice and clear now. Had to remove the throttle valve to see it. P0401 has not come back. Thanks again! Bob

@ramayo824 Yes air should pass through the manifold.Seeing you have the tube off start up the engine, exhaust should come out the hole in the manifold if it does not you have blockage.
Question...I turned on my car to check the air pump it pumps for a while then stops, Should the air pump continue to pump air? is that what i need to replace for my 410 code?

@skylarjh88 It is normal for the pump to run only for a short time at start up.

This helped me understand what my mechanic is talking about, but we cannot find part number 1997265, the secondary air injection switching solenoid valve, anywhere. GM Parts tell us that it is discontinued but do not offer an alternative. Any ideas?

@clm3nd I checked my sources and they do not have that solenoid.I would be rushing to the salvage yards and getting as many as i could.
