I have a 2001 STS that had the same problem - Service Engine light and returned the P0410 code. It ended up being a small rubber hose that had pulled off one of the plastic lines in the secondary air system. In fact, I just fixed this last night.

Pull off the top engine shield (the one covering the motor and the fuel injectors, not the plastic one at the front of the car) and look for loose lines, hoses or wiring.

Also - if you remove the shroud under the engine (you just have to pull out a bunch of plastic retaining plugs) you can get at the lower elements of the SAS. Look for loose lines, hoses or wiring.

You could be fortunate and just have a loose line. Does the caddie run OK?

Havent a clue ,from this old dinasaur to a liitle young mechanic sorry have a clue.You see here in spain they stick a nozzle up the exhaust ,and run engine at 2500rpm then check readings .Only vehicles from 2005 use OBDII in europe and most of these vehicles from this date use encrypted software so its a complete waste of time buying a snap on scanner because it would only read a funny code number that wasnt releted..Turkey for the dealer and bread and lard for the rest of us mechanics

Trouble code P0410 with many others


P0410 code is for secondary AIR injection system. this injects air into the exhaust system to lower emissions, its pointless and wont effect your vehicles performance. It doesn't make the car any more efficient it just "dilutes" the exhaust emissions

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.

Hi i hava two code im ford focus 2007 p0491 and p0410 no can fix what doin


Hello,

P0491 is a Secondary Air System fault Bank 1.

Bank 1 refers to the passenger side off the engine. The combination valve for secondary air injection did not preform as it should & set a fault. The valve is located under the plastic engine cover at the rear of the right cylinder head.

There is a plastic tube from the air pump to the valve that breaks, the valve sometimes fails, there is a vacuum hose that opens the valve that also sometimes fails & rarely the Air Injection Vacuum Control Solenoid Valve fails. The plastic tube unpluged/cracked or failed valve are the 2 most common failures.

If it's a vac leak it's in the small hose from the solenoid valve to the combination valve. The super charger may affect the vacuum, but I would expect to see more codes if it was really messing with things. The air injection system only runs for about 1.5 minutes on cold starts. If the plastic tube is broken you will hear what sound like a small exhaust leak.

P0410

What does that mean?

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.

When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.

Am looking for what the carmd code p0410 means for a 2004 buick ranier - my car md is not working right.


CEL light/code P0410, secondary air system fault.
DTC P0410 - Secondary Air Injection System

Suspect -
Relay/fuse (box B) loc 3 ,15amps
Pump $434(new) / $243 (Remanufactured) / $95 (used,Ebay)
solenoid $73
check valve $18
http://www.autopartswarehouse.com

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.

Checked why engine light was on and it gave code P0410 Secondary injection system. to me this is very vague. can you help?


that code indicates a problem w/ the air injection system, a part of the emissions system. you should check the air pump, solenoid, check valves and vacuum hoses of that system. the emissions sticker under the hood should give you a detailed enough diagram of where the components are

I have an engine management light come on - tested - came up with a code PO410 - what is the next step?


P0410 is the error code for Secondary Air Injection System Malfunction
The secondary air injection pump pumps air into the exhaust to help heat the catalytic converter at cold start. This lowers the emissions at an otherwise high emission time.
A malfunction means that computer has registered either a pump failure (common on some models), fuse blown, or improper catalytic converter function.
Check your fuses. Whether you find a bad fuse or not have the codes reset. Some auto Zones can read and reset the codes. If the error comes back you may want to consider having the exhaust system checked.Problems with the catalytic converter\converters can have a large impact on your MPG.
