SOURCE: Secondary air supply failure
I have a 2005 Envoy with a 4.2..... Just recently the check engine light illuminated so I read the code after replacing the 20amp fuse labeled cigar. My OBDII connection had no power so if you plug your reader in and nothing check the fuse under the hood labeled "cigar"
After pulling the code P0410 Secondary Air Injection Malfunction I checked the operation of the air pump by removing the hose connected to the solenoid. By the way the solenoid is located on the pass side of the engine top towards the back. After pulling the hose off the solenoid I started the vehicle when it was cold and after 20 seconds or so the pump should turn on and blow air out of the hose. Once I verified the pump was operating I pulled the solenoid then placing jumpers from the Positive & Negative of the battery to the pins on the solenoid. You should be able to hear the solenoid click which says its operating. But mine did nothing so I read across the pins with an Ohm meter and verified the coil was good.
So take some good penetrating oil and fill the inside of the valve with it. You can see the plunger shaft assy in the opening and thats the area you want to fill with a good penetrating oil!!!! Let it sit for a couple of hours keeping it full of oil. The housing is aluminum and the shaft is likely to be a brass material so rust is not possible. Its caused by a buildup of carbon!! The penetrating oil will soften the carbon which in turn will free up the plunger!! MINE WORKS GREAT NOW and plus you will save around $140.00 if you were to buy it from the dealer!!! Or $80.00 aftermarket from RockAuto.com

p0410 secondary air injection valve malfunction..
Just know that diagnosing this is time consuming since the "system" is only active for a few seconds on cold start.
1.) wait for your car to be "cold" or 4 hours. Disconnect the hose from check valve (located passenger side--the transmission dip stick is attached to the bolts that hold it to the block). Start the truck, you should hear a nasty sound for about 30 seconds to a minute. If you don't its your check valve.
1a.) If it is your check valve, you can try to clean it. Get some throttle body cleaner, remove the check valve spray thouroughly (I did it a couple of times to get all the carbon and rust out) and let dry reinstall and follow above instructions. If no go replace check valve
2.) wait for your car to be "cold" or 4 hours. remove the fattest hose from the underside of air intake hose (I think thats where it is, I have a CAI so Its hard to know where it is exactly OEM) and from the check valve. Have someone else start the truck. Feel the hoses, you should feel sucking and blowing (I can't remember which is supposed to blow / ****) If you don't feel anything then its the pump (maybe -- read further)
2a.) check fuses there are about 3 in the manual listed for air pump (if bad fuse replace and retest, make sure to check the fuses after to make sure that the pump isnt blowing fuses)
2b.) Locate the air pump its driver side mid car just behind the cross member for the frame. There are two wiring harnesess one that goes into the relay (grey box) and one that has two fat wires (thats the power plug for the pump.) disconnect that one, wait for cold start and start truck while having a multimeter attached set on DC mode. If you get a reading of 0 then replace the relay. if you get power 12-15 volts replace the motor.
3.) If both the check valve and the pump are testing out ok it could be a clogged hose.
There are only 3 parts to this system, Check Valve ($125), Air Pump ($280) and Relay ($50). parts4chevys.com has it listed as a check valve. $128 list. Good luck and hope this helps

The water comes from exhaust system /condense/ because the check valve does work properly. The check valve is located on left top side of the engine where the hoses from the air pump connect to the exhaust.

Typical **** Ford design. Try rotating the bowser nozzle (in the filler hole while fueling) to 3 o'clock or 6 o'clock or 9 o'clock, or even upside down if necc. Or you can try pulling the trigger part-open instead of 'flat-chat' (fast fill) Problem common to 5-10% of cars, good luck.
