Service engine soon light

Was told that when this light came on that the air injection pump had water in it and needed replacing. What does this pump do and where it is located on the engine?

    I have a 2001 grand prix gt with similar issue. i was told by dealership that there was water in the secondary air system, which included some type of air pump. The system has to do with emissions, so the car will run but won't pass inspection...they wanted a lot of $$$ for the work though, so be prepared!

Have you plugged in a diagnostic computer in? My service engine light came on, and I went to AutoZone and had them plug the computer in and it gave me a readout on what was wrong. It might be something else.

Secondary Air Injection System Description
The secondary air injection (AIR) system helps reduce exhaust emissions. The system forces fresh filtered air into the exhaust stream in order to accelerate catalyst operation.
I have had no luck on the location, but it is down low on most GM near the front of car under the hood, it is very big with hoses comming out of it and going to the engine,

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.

Service engine soon light, and code P0410 Secondary air injection system malfunction.. what are the items to look for? what normally fixes the fault? Thanks


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:
1. Prep vehicle.
2. Raise vehicle on hoist.
3. Remove shield covering AIR pump.
4. Remove hose and vacuum lines from pump and solenoid.
5. Remove AIR pump inlet hose. Do not re-use.
6. Disconnect electrical connectors from pump and solenoid.
7. Remove pump mounting bolts and pump.
8. Transfer isolators from the old pump to the new pump.
9. Install new AIR pump and bolts to vehicle. Tighten the bolts to 17 N.m (12.5 lb ft)
10. Route new hose assembly up between engine and fender. It should come up near the area between the battery and the coolant bottle.
11. Connect new inlet hose to pump inlet.
12. Connect old outlet hose to pump outlet.
13. Connect electrical connector to pump.
14. Connect electrical connector for solenoid to connector on the new hose assembly.
15. Connect the hose with the white nipple to the vacuum source hose.
16. Connect the remaining hose to the shut off valve.
17. Install shield covering AIR pump.
18. Lower vehicle.
19. Remove coolant reservoir nut nearest the battery.
20. Route new hose assembly between the battery and the coolant reservoir with the solenoid on top.
21. Install the solenoid bracket onto the coolant reservoir stud and reinstall the nut back into the vehicle.
22. 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.

Hope that helps......... //

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.

I have a 2002 LS, and my "service engine soon " light is on. I have read that it could be the secondary air injection pump. Could someone please tell me where it is located, and if there is a...


The Service Engine Soon light could be on because of literally hundreds of different reasons. Most of the 2002 Buick Regals are not even equipped with a secondary air injection pump. (The only ones that have them are California emmissions cars) What fault code are you trying to diagnose? Knowing this would make a huge difference in how you go about trying to diagnose and fix it. You didn't mention it, but I am assuming you are talking about a 3.8L V-6 Engine? (Engine size is nice-to-know information if you are trying to diagnose an engine control problem) Also, if you are going to try and diagnose a secondary air injection system, you will need a scanner that has the capability of enabling computer outputs. This is necessary to turn the pump circuit and the injection solenoid circuit on and off to verify what the problem is.

If your Regal is equipped with an air injection pump, it will be located under the car between the front bumper area and the left wheel house. You will have to remove the left front wheel and the left wheel house liner to access it.

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.

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

My service engine light went on and brought codes P0492 & P0493 . I was told it was the secondary air injection system. I brought the car in to have it checked out and they said the secondary air pump...


I'm not sure if you fixed your problem yet but I had some similar gremlins on my 2001 540. Just a word of advice. Ensure that the tube from the air pump to the manifold is clear. This can occasionally get blocked and this is what causes the air pump to over heat and fail in the first place. after replacing a couple of air pumps, I learned this the hard way.
