P0411 - secondary air injection system, incorrect flow. Basically it means that too much air is entering the engine because one or more vacuum tubes have failed.
Unfortunately this is not covered by the warranty and you will have to fix it yourself. Inspect every single vacuum tube until you find the cracked one then replace it - it's a simple job for someone who has done that before and really knows what he's doing. If you are not such a person then take it to a repair shop, it will cost you less than $250, part included.

SOURCE: What would cause a code P0411?

Code P0411 usually indicated problem with secondary air intake. Since you just had air filter changed, try running engine without the filter. If the code disappears the problems with the new filter or its installation.

I own a 2008 GMC Envoy Denali, 2WD. Yesterday the engine would barely idle and numerous lights on the dash came on including the check engine light. I had a friend check the diagnostic codes and it came up...


Five days prior to this, the battery had to be replaced. The engine was started without the pause for two minutes ?????? Where do you people come up with some of this stuff ? Pausing for two min. before starting has nothing to do with it . DTC P0651: 5-Volt Reference 2 Circuit
Some of the engine sensors on your vehicle work off of a steady 5 volt supply by the PCM - engine computer . One of these sensors is short internally bring down the PCM .

That's why it wasn't running good ,an lights lit on the dash. Your best bet , take it to GMC dealer .
No where in GM service info does it say after replacing the battery that you need to wait two min. before starting .
Position the positive battery cable (1) to the battery.
Tighten the positive battery cable bolt.
Tighten
Tighten the bolt to 15 N·m (11 lb ft).
Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

2008 Trailblazer P0411 code


The Secondary Air Pump is turned on and off by the ECU. The ECU looks at live data from the O2 sensors. The flow rate and direction of flow, is controlled by the cutoff valve. I believe this is what you are looking for. GM has a few different arrangements so you will have to call the parts department at the Dealership and they will tell you whether you have a cutoff valve, check valve, solenoid, or if is controlled by the air pump itself. If there are anymore questions feel free to write back. Please let me know how the repair is going, good luck.
