SOURCE: I need to see the "how to's" in replacing the one way check valves on my 2001 gmc sonoma 4.3

On the 2001 gmc jimmy 4.3L v6 engine there are two air pump check valves: there's a pipe (about 1" diameter) that comes off each of the exhaust manifolds. the check valves are screwed onto those pipes. then a rubber hose (about 1.25" outside diameter) is clamped to the front of each check valve and connects to the air pump, which is hidden behind the vehicles grille in front of the radiator. typically, if you need to replace these (the life expectancy is about 3-4 years), it starts a chain of events that might be as follows: during the wintertime, water from the exhaust leaks through the worn out one-way check valves, and ends up in the air pump. the water freezes, and the ice jams the air pump, which may or may not ruin the air pump, but which usually blows the air pump fuse, which is impossible to find if you're rummaging around the passenger compartment fuse box or the under-hood fuse and relay box. it ain't there! so if you're looking under the hood leaning up against the front bumper, slide to your left around the passenger side headlight. now you should be looking at the battery, leaning up against the passenger side fender. look down between the battery and the fender. you have to push a few things out of the way, but there you will find a green 30 amp blade fuse (about 1" x 1" fuse--and $2.99 at autozone). this blown fuse should have triggered the check engine light and a DTC (diagnostic trouble code) of p0410 (secondary air injection system). for that vehicle there is a TSB (technical service bulletin) put out by gm (bulletin # 04-06-04-015; march 2004). if you want to print out some literature about all that i've mentioned just surf on over to http://www.obd-codes.com/p0410 for more links and documentation. my credentials: self-proclaimed auto mechanic for 26 years (sorry, no ase certification yet [but still trying to find time to study for the tests]) and college dropout (after 3 years of electrical engineering)--so, in other words, don't believe a word i say; just go to that website and get it straight from the horse's... 
Good luck and hope this helps. I know you have a Sonoma but we have the same platform. I am thinking of buying a set of headers without the Air injection system and having the jimmy dyno tuned again to eliminate the service engine light and recalibrate the ECM to eliminate the air injection pump.

secondary air injection system shut off valve stuck how to fix it

SOURCE: secondary air injection system

This is a pump that sits underneath your front bumper on the passenger side. It is about the size of a baseball and has two hoses going into it. I would suggest you replace it yourself as it would cost you about $360.00 if you were to go through the dealer.

Water intrusion is what will typically kill these electric pumps. There is a Technical service bulletin (#04-06-04-015) Regarding this problem, according to the tsb, you will need a new pump and there is a hose assy. #12590627) that has you reroute the pump from future water intrusion or it is guaranteed to fail again.

Although I have had water in the pump I did not see any indication of the inlet hose as the cause. It was suggested that the one way metal check valves ($15.00) that mount to the rt & lt exhaust manifold are worn and allow water from the exhaust to get sucked back into the pump. I first replaced the pump and within a week of dry weather driving the light came back on. I checked the pump and it was again full of water. I just replaced the valves which had deteriorated on the inside. So hopefully this will eliminate the problem. Note - The valves are impossible to remove without removing the 1/2 tubes (held on with 2 nuts) they are attached to the manifold with. The valve threads seize to the tube thread and had to be clamped in a vise to remove - I actually had to hacksaw the valve section to get it off the pipe. Careful as not to damage the threads.

Good luck and try autopartsdirect2you for a new pump and it has life time warranty.

TSB #04-06-04-015 - (Mar 22, 2004)

Condition
Some owners may comment on the check engine light being illuminated. Upon investigation, the technician may find a DTC P0410 indicating that there is a concern in the secondary air injection system.

Cause
Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump.

Correction
Replace the AIR pump and install a new inlet hose and solenoid tube assembly using the following procedure:

Prep vehicle.
Raise vehicle on hoist.
Remove shield covering AIR pump.
Remove hose and vacuum lines from pump and solenoid.
Remove AIR pump inlet hose. Do not re-use.
Disconnect electrical connectors from pump and solenoid.
Remove pump mounting bolts and pump.
Transfer isolators from the old pump to the new pump.
Install new AIR pump and bolts to vehicle.

Tighten
Tighten the bolts to 17N·m (12.5 lb ft)

Route new hose assembly up between engine and fender. It should come up near the area between the battery and the coolant bottle.
Connect new inlet hose to pump inlet.
Connect old outlet hose to pump outlet.
Connect electrical connector to pump.
Connect electrical connector for solenoid to connector on the new hose assembly.
Connect the hose with the white nipple to the vacuum source hose.
Connect the remaining hose to the shut off valve.
Install shield covering AIR pump.
Lower vehicle.
Remove coolant reservoir nut nearest the battery.
Route new hose assembly between the battery and the coolant reservoir with the solenoid on top.
Install the solenoid bracket onto the coolant reservoir stud and reinstall the nut back into the vehicle.
Use a wire tie to keep the new hose assembly away from the engine. On four cylinder engines, tie to the AIR outlet hose. On six cylinder engines, tie to an available hole in the radiator fan shroud.

What solution on p1445 secondary air injection system switching valve no2 bank2 stuck close


Year make and model? This code usually refers to the purge control valve circuit being high

Jul 10, 2015 | Cars & Trucks

I have a service engine soon light on and have hooked up an OBD11 reader to it and got code P0410 pertaining to a secondary air injection problem. hoses are fine, pump is new.


P0410 Oldsmobile - Secondary Air Injection System Malfunction

Possible causes: - Faulty Vacuum hoses damaged
- Faulty Air Pump inoperative
- Air bypass solenoid harness is open or shorted
- Air bypass solenoid circuit poor electrical connection
- Air bypass solenoid leaking/blocked or stuck open/closed
- Air diverter valve leaking/blocked or stuck open/closed

Tech notes: Visually inspect AIR pump and AIR bypass valve harness and connector, if connector are OK, then replaced AIR bypass valve.

When is the code detected? The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system.

Possible symptoms: - Engine Light ON (or Service Engine Soon Warning Light)
- Engine hesitation

P0410 Oldsmobile Description An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump. The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. The PCM enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves. When the AIR system is inactive the shut off valves prevent air flow in either direction.

Secondary air injection valve stuck open


2 problems. bad dampers in HVAC.
why not scan the PCM. using a scan tool. (rented, or loaned they are everywhere)
scan it , and post the DTC errors, all cars , USA from 1988 to now.
all cars. if not in USA say so. steps change.

    P2440 refers to the Secondary Air Injection system. It means that the switching valve is stuck open. We already replaced the secondary air flow pump, now it's telling us that's its the secondary air flow sensor and the valve is stuck open. the code is coming up P2440

    I have the following codes po410 and po491.......can u please tell me what they are so I can get my car fixed asap


    P0410 - SECONDARY AIR INJECTION (AIR) SYSTEM
    P0491 - SECONDARY AIR INJECTION (AIR) SYSTEM INSUFFICIENT FLOW (BANK 1)

    Secondary air injection (trademarked as Air Injection Reactor) is a process where fresh air is injected into the exhaust system to allow for a fuller combustion of exhaust gasses.

    The possible causes are:
    SAIR pump low or now air flow
    SAIR bypass solenoid leaking/blocked or stuck open/closed
    SAIR diverter valve leaking/blocked or stuck open/closed
    SAIR air hose restriction
    SAIR vacuum hose restriction or leaking

    Check to make sure your air filter isn't dirty - and replace if needed. Otherwise I would suggest having your local trusted auto repair facility diagnose and repair the issue. A scan tool will be needed to properly diagnose the issue.

    Dtc 1442 and 1446


    P1442
    The code actually has another character in front of it, most likely a P (Powertrain) code as they're most common, although it could also be a B (Body) or C (Chassis) code. So it's likely P1442 and it's description is Evaporative Emission Control System Leak Detected. That code is specific to Toyota vehicles, although it seems nearly identical to the generic code P0442. This error pertains to the emissions system in the car. You now have the choice of either taking the car to a qualified technician or you can try a few troubleshooting steps yourself. If you're not mechanically inclined, I would recommend you change the gas cap to a brand new Toyota one (not a cheap aftermarket one), reset the code and see if it comes back. If the code returns there are additional steps you can take. Take a look at this P0442 article for other ideas.
