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.

Why does the check engine light keeps coming back on after repairing/replacing secondary air injection system, code P0410?


a lot of times you actually have to drive the vehicle in order for the engine light to reset. sometimes you can have the engine light reset with a scan tool unless a hard-fault code thenone has to do was known as the drive cycle.this could very firm anywheres to 72 150 miles depending on the manufacturer.

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.

My check engine light came on my dash. Audi 2004 2.7 TT


the problem can be caused by vacuum leaks .. in some engines the vacuum hoses pass above the engine where they can get very hot .. they crack, split or just leak .. this causes several bad things to happen including the secondary air injection problem (vacuum operated valves) ... on at least some cars like the passatt there is a vacuum hose kit available that replaces all the critical hoses .. maybe audi has the same type repair kit ..

P1414 P1417 2003 discovery


Those codes are associated with the Secondary Air Injection. I too had the same codes on my 2003 Discovery. From reading Land Rover forums online, I determined that it is likely the Secondary Air Injection Solenoid that has gone bad. It is a $20 part that you can buy on atlanticbritish.com and install yourself without any tools. The hardest part was getting the original solenoid off -- it is simply clipped on with a plastic arm that is built into the part.

Does your Secondary Air Injection come on at random times? Mine would also come on sometimes at stop lights even after the engine had already warmed up. That is another sign that you might have the same problem and need to replace the solenoid. Before I replaced the solenoid, I had turned off the check engine light and noticed it came back on immediately after the secondary air injection went off after starting the truck cold a few times. After replacing the solenoid, I have yet to see the check engine light return.

Hope that helps.

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.

Check engine light comes on every three weeks about.reads secondary injection air system. can you help?


With regards to the secondary Air Injection system, this is basically an inspect and replace broken hose detail.
Leave the inlet hose disconnected and start the engine. Listen and feel for exhaust hissing at the check valves.The check valve(s) will make like a gurgling sound as air is drawn in However , if exhaust is felt or heard replace the valve. Get a scanner and turn off the check engine light. Hope this works out for ya.

Secondary Air Pump and MPG Gauge


Fist of all this is a 2009 vehicle and if you are having any problem with a secondary air pump with this NEW vehicle it should be under warranty or should be a recall and should be fixed for FREE, by BMW. This vehicle in my opinion is way too new to be having such problems, that pump must have been defective. I also believe that thier may be other problem going o with this vehicle. MY SUGGESTION IS TO TAKE THIS THING BACK TO BMW ADN HAVE THEM FIX ALL YOUR ISSUES FOR FREE. Good Luckand thanks for using FIX YA
