I am thinking that my Air Pump might have water in it.

My question is where do I locate the air pump?

Thanks.

Welcome to the forum.
I can't answer your question but maybe the answer is in one of the posts here;
search results for P0410
:)



I think you need 10 posts before you can use the search feature. Kind of odd as that new people here would need it the most.:undecided

If you're talking about the air suspension pump, it is above the right rear wheel.

The AIR pump is under the vehicle, on the inside of the frame rail near the driver's area. If you search around a bit, there's a few threads on trouble shooting.

I had the same code over the summer, and it ended up being the check valve, mounted on the passenger side of the engine block. Easy fix, the part is about $70 if i recall correctly.

the air pump is under the truck on the driver side by the floor board. pull the hoses off the pump and see if you have any water coming out. with the hoses off if your truck has been sitting for a while around 8 hours start it up and if your air pump is working it will sound like a vacuum cleaner. then it is going to be your check valve that is bad. that is located on the passenger side of the engine blockaround the 4th or 5th exhaust manifold, just above it. it has a hose off the back, electrical connection on the top and two bolts connecting it the block. i just fixed my check valve. i found the parts at www.autopartsgiant.com for around $88.80 shipping included.(check valve and gasket) Good Luck hope this helps:coffee
