Sounds like they want to cover all bases. When the truck is first started you should hear the pump run. If it does you don't need the pump. While the engine is running remove the hose from the check vavle, exhaust should not be coming out of the tube, if it does the check valve is bad. There is also a vacuum hose going to the check valve , make sure it is hooked up. It's not to hard to diagnose this code. Pumps are approx. $150.00 Check valves around $80.00

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.

Code 410 comes up on 2002 Saturn need advice


Hi there:
This code is for the Air Injection Reaction (AIR) Pump they often will get water inside of them and the pump will fail. In this case the pump will need to be replaced.



DTC P0410 - Secondary Air Injection System Malfunction

The P0410 code refers to the emissions system. The AIR pump puts air to the exhaust to lower emissions. It takes in outside air and pumps it through two one-way check valves into each bank of the exhaust.


About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.

Possibly symptoms include:
MIL illumination obviously
Hesitation on acceleration
Noise from a bad/stuck AIR pump

A code P0410 may mean that one or more of the following has happened:
Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump
Blown AIR pump fuse due to freezing up


Possible Solutions:
Note: There is a technical service bulletin (TSB) regarding this code for a number of GM models. The TSB calls for the replacement of the AIR pump and the installation of a new secondary injection hose. The TSB can be found on this ACDelco site.

Additionally, if you simply replace the AIR pump the problem may return again (and again). If you replace the pump, also clean out the hoses and replace the one-way check valve. If this is on a GM model that the TSB applies to, follow those instructions in the link above. In a few cases, people have put a small hole in the rubber cover on the pump which allows any water to drain out.

Also, please note that this may be covered under the emissions warranty on the vehicle. If your vehicle is out of bumper-to-bumper warranty, check if the emissions warranty is still valid!

Replace the AIR pump AND one-way check valve
Test and clean the AIR pump AND test and replace the one-way air check valve
Replace the AIR pump inlet hose
Replace the AIR pump fuse (found under the hood)


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

What does this code mean? P0410


Diagnostic Test Code (DTC) P0410 indicates that your secondary air injection system is not functioning properly.
Not all 2001 Chevrolet Bazers are equipped with secondary air injection. The secondary air injection system was added to vehicles that were to be sold in certain areas where the emissions laws required it, like the State Of California.

The Powertrain Control Module (PCM) monitors the system by commanding the secondary air blower motor to run and the air injection solenoid to open. This causes additional oxygen to enter the exhaust system. The PCM then monitors the signal from the oxygen sensors to see if the commanded air has in fact, entered the exhaust system. Code P0410 sets when the PCM has commanded the blower motor on and the solenoid open and there is little or no change in the oxygen sensor signal.

GM has had some problems with these systems and there has been a Technical Service Bulletin (TSB) issued that addresses some of the known concers. Below is a brief description of the TSB and the issues involved.

Bulletin No.: 04-06-04-015A
Date: November 28, 2006
TECHNICAL
Subject:
LN2, L43 or L35 Engine SES/MIL Light Illuminated, AIR Pump Ingesting Water and DTC P0410 Set (Replace AIR Pump and Inlet Hose Assembly)
Models:
1999-2003 Chevrolet Blazer, S10
1999-2001 GMC Jimmy
1999-2003 GMC Sonoma
1999-2001 Oldsmobile Bravada
with Vortec 2.2L I4 or 4.3L V6 Engine (VINs 4, 5, W - RPOs LN2, L43, L35)
Condition
Some customers may comment on the SES/MIL 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...

The bulletin goes on and gives detailed information on how to perform the repair and the part numbers of the replacement parts needed to do so. Your local dealer can provide the parts for you and you can probably get them to print out a complete copy of the bulletin for you. It is not really hard to do if you want to do this yourself.

A new pump, or simulator!

What signals the ECU, if the seconary Air Injection system isn't working?
H20 sensors, if running rich > Xtime throw code!
The pump only runs when the engine is cold, so the air & rich fuel mix is burnt in the exhaust manifold, so there's less Emission.

Service Engine Soon light came on. Took the car to Auto Zone the code P0410 popped up. What does this mean?


This is a secondary air system malfunction code.....

The Secondary Air System pumps outside fresh air into the Exhaust System during cold engine start up. This additional air helps burn up the highly rich exhaust emissions that are produced when the engine is warming up. The Secondary Air System typically has an Air Pump and some tubes or plumbing to route the air. The system also has a solenoid and Check Valve(s) to control the air flow.

Common Problems That Trigger the P0410 Code
  • Defective Check Valve(s)
  • Faulty Air Pump or Air Pump Relay
  • Faulty air control solenoids or vacuum lines
  • System may be restricted or plugged
Let me k now which direction you want to head in and we will check further

Received trouble codes p0410 and p1599. The car has trouble staying started and sometimes stalls at a stop. It also seems to idle up and down even when engine is running but, is in park.


P0410 Secondary AIR System Performance

P1599 Engine Stall Detected

Leave it to GM to use a computer code to tell you your engine died. The AIR system was a mistake they felt like was best corrected by continuing to use it. The system is similar to EGR function where it injects air into the exhaust for emissions. When it screws up, and it does often, it makes the car run horrible and is usually expensive to fix because the parts are hard to find. I would call a local GM dealer, give them the codes and see what they estimate the cost to fix it is. You might consider trading it in after that.

Code P0410- Secondary Air Injection Malfunction


The air injection reaction system (AIR) is on all 2004+ 4.2's. There is an electric blower under the truck, tucked inside the frame rail about under the drivers seat. The blower draws it's clean air from a hose tied into the air inlet tube between the airfilter box and Throttle body, pressurizes it slightly and blows this clean air into a port in the cylinder head directly above the exhaust manifold, dead center. There is a can shaped check valve bolted to this port with the air hose clamped to it and an electrical connection. The most common failure point of this system is this check valve. Remove the hose, the electrical connection and 2 bolts and it's off. Very easy. Problem is, it's about a $125 dealer only item.:banghead: The check valve gets corroded/cruded up and doesnt seat. Let it go long enough and moisture from the exhaust can back flow into the system and destroy the $$$ electric air blower. I'd start by removing and checking the valve and check the hoses for water.
Inspect the air pump and wire harness under the Trailblazer's frame rail, since you did mentioned that your had your transmission serviced and they would have had to work under there to remove the transmission pan to replace the transmission fluid and filter. There are 2 fuses you need to check also. AIR fuse 60amp....AIR solenoid fuse 15amp.
