    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.

    SOURCE: Read a PO410 code,1996 850 GLT volvo, secondary

    The most common cause is either a bad air pump (under your battery tray) and/or a bad SAS check valve which is connected in to your exhaust next to the firewall in the engine compartment.  It could also be a bad relay for the motor.  Less common, but possible, other bad components are the vacuum solenoid that controls the SAS valve, which is located by the radiator or a broken/leaking vacuum line to or from the solenoid.

    You can test the motor by jumping the relay or applying 12v straight to it.  If the motor runs it most likely is not the problem.  If not, it's likely that there is water in it and you should replace both the motor and SAS valve.  The SAS valve is a pain to get unbolted, at least on turbo cars.  You can check the solenoid by just making sure there is vacuum going to the SAS valve a few seconds after starting up the car cold, and checking the lines for any obvious wear in the rubber elbows or breaks in the plastic line.

    SOURCE: Code P1420 suggests replacing the secondary

    17828/P1420/005152 - Secondary Air Injection Solenoid Valve (N112): Electr. Malfunction Possible Causes

    • Secondary Air Injection Solenoid Valve (N112) faulty
    • Secondary Air Pump Relay (J299) faulty
    Possible Solutions
    • Check Secondary Air Injection Solenoid Valve (N112)
    • Check Secondary Air Pump Relay (J299)
    The secondary air injection pump relay (J299) is inside the engine compartment, left side, behind air cleaner housing, under a black plastic protective cover you can lift up to reveal it. It's near the brake fluid reservoir beside the odd black plastic cover for the wiring harness beside the shock absorber tower.

    Rating my suggestion let's me know how helpful it was correcting your problem. Your rating is truly appreciated and would take the very least of time and effort away from you. Thank you

    SOURCE: OBD Code P0410, Secondary Air Injection System.

    Usual causes are air in air pump, solenoid malfunction, the secondary air check valve, or loss of power to pump solenoid. Pinched, loose, cracked, or broken hoses can also cause this code.

    DTC P2430 : Secondary Air Injection (AIR) System Pressure Sensor Circuit
    Circuit/System Description
    The secondary air injection (AIR) system aids in the reduction of hydrocarbon emissions during a cold start. The system forces fresh filtered air into the exhaust stream in order to accelerate the catalyst operation. An electric air pump, the secondary AIR injection pump, provides filtered air on demand to the AIR control solenoid valve/pressure sensor assembly. The AIR control solenoid valve/pressure sensor assembly controls the flow of air from the AIR pump to the exhaust manifold. The AIR solenoid relay supplies the current needed to operate the AIR control solenoid valve/pressure sensor assembly. A pressure sensor is used to monitor the air flow from the AIR pump. The engine control module (ECM) supplies the internal pressure sensor with a 5-volt reference, an electrical ground, and a signal circuit.

    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.

    I replaced my secondary air check valve on my 2001 chevy tahoe but code 1416 still comes up. what else can i check


    here is what i found on p1416.



    P1416 Chevrolet
    P1416 Chevrolet - Secondary Air Injection System Bank 2
    Possible causes
    - Faulty Secondary Air Injection (AIR) pump
    - Secondary Air Injection check valve bank 2
    - Secondary Air Injection (AIR) pump electrical circuit fault
    - Blocked Secondary Air Injection (AIR) system

    When is the code detected?

    The P1416 code is set when no O2 sensor voltage change is detected by the Engine Control Module (ECM).


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


    P1416 Chevrolet Description
    An Secondary Air Injection (AIR) pump is used on this vehicle to lower tail pipe emissions on start-up. The PCM supplies a ground to the AIR pump relay, which energizes the AIR pump. The Powertrain Control Module (PCM) monitors the HO2S voltages to diagnose the AIR system. During the AIR test the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low and the short term fuel trim should go high.

    What does it means p2258 code for 2003 Ford Focus , Smog test Failed


    P2258 Secondary Air Injection System Control A Circuit High

    http://www.motorcraftservice.com/vdi...f/OBDSM505.pdf

    Secondary air systems typically utilize an electric air pump as well as one or two electrically controlled check valves to deliver air into the exhaust manifold.

    The only vehicle which uses secondary air is the 2.3L PZEV Focus. The Focus uses a system with ported air. This means that airflow is delivered to each individual exhaust port. The secondary air pump is energized soon after start-up while the fuel system is in open loop and icing conditions are not likely. After the O2 sensors warm up, the secondary air pump continues to be energized while the fuel system goes into closed loop fuel. The secondary air system continues to run in closed loop fuel until the air pump is de-energized. The typical time period in which the AIR pump is energized is approximately 12 seconds.

    The AIR pump flow check monitors the HO2S signal at idle to determine if secondary air is being delivered into the exhaust system. The air/fuel ratio is commanded open-loop rich, the AIR pump is turned on and the time required for the HO2S signal to go lean is monitored. If the HO2S signal does not go lean within the allowable time limit, a low/no flow malfunction is indicated. (P0411)

    The electric air pump draws high current and must be energized through a separate relay. Both the primary and secondary circuits are checked for opens and shorts. First, the output driver within the PCM (primary circuit) is checked for circuit continuity (P0412). This circuit energizes the relay and the vacuum-operated check and control valve(s). Next, a feedback circuit from the secondary side of the relay to the PCM is used to check secondary circuit continuity (P2257, P2258).
