P0411 Secondary Air Injection System Incorrect Flow Detected
p0411 is a generic code, probably a vacume leak,vacume hose broken check this first, check the air pump turn on the car but it needs to be cold, you should hear a high pitched whine, this is the air pump running,there are 2 hoses one suction one blowing thishose should be going from the air pump to the air cleaner disconnect that and see what the volume is should be pretty strong.
But mostly you probably have a broken vacume line somewhere

I HAVE THIS CODES P0410-P0412-P042-P0411-P0491 COMING OUT WHEN I DID A CHECK ENGINE LIGHT TEST AND HOW CAN I FIX IT PLEASE HELP ME BEFOR I GIVE UP AND JUNK IT AND I DONT WANT TO DO THAT TO MY CAR.


codes p 0410, 0411, 0412 all refer to the secondary air injection system--malfunction, incorrect flow detected and circuit malfunction ===causes are --wiring--sir valve---air solenoid--ECM--air pump, air hose/s--ECM
code p 0491 refers to secondary air injection bank 1 --malfunction or insufficient flow=== causes are the same with a mechanical fault added
so to analyze -- the most common cause is air hoses, followed by valve or solenoid of the air injection system followed by ECM which be as little as a bad pin connection in the wiring

3.2l. What are the probable causes of DTCs P2006 and P2007?


code p 2006 refers to intake manifold air control actuator , bank 1 --actuator stuck closed or for 2007 , the intake air manifold control actuator bank 1--solenoid stuck closed === causes ---wiring --- intake manifold air control actuator / solenoid ---mechanical fault
so for both it is either the actuator or the solenoid that is showing the codes

Code p2004 saying intake manifold runner control sturck open. bank 1


code p 2004 has two references
intake manifold air control actuator , bank 1 --actuator stuck open====causes ---wiring---intake manifold air control actuator ---mechanical fault
second reference is
intake manifold air control solenoid , bank 1 --solenoid stuck open===causes ---wiring--intake manifold air control solenoid ---mechanical fault
probably means the same as what you have but in a more easy to understand method

04 Focus coding P2004 and P0411 what does this mean?


Your P2004 code relates to inlet manifold air control actuator or solenoid on bank 1 stuck open, your code PO411 relates to secondary air injection system, (AIR ) incorrect flow detected. Obviuosly both codes are linked to one fault,

Abs code PO411


That is not an ABS system code, it is a powertrain fault code.P0411 - Secondary Air Injection System Incorrect Flow Detected, most common cause is a failed electric motor in the air injection pump.
The pump is under the hood.
Other Possible causes- Faulty Vacuum hoses damaged
- 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

DTC P0411 : Secondary Air Injection (AIR) System Incorrect Air Flow Detected

DTC P2440 : Secondary Air Injection (AIR) Valve Stuck Open

DTC P2431 : Secondary Air Injection (AIR) System Pressure Sensor Performance
Circuit/System Description
The secondary air injection (AIR) system aids in the reduction of hydrocarbon emissions during a cold start. The system forces fresh filtered air into the exhaust stream in order to accelerate the catalyst operation. An electric air pump, the secondary AIR injection pump, provides filtered air on demand to the AIR control solenoid valve/pressure sensor assembly. The AIR control solenoid valve/pressure sensor assembly controls the flow of air from the AIR pump to the exhaust manifold. The AIR solenoid valve relay supplies the current needed to operate the AIR solenoid valve/pressure sensor assembly. A pressure sensor is used to monitor the air flow from the AIR pump. The powertrain control module (PCM) supplies the internal pressure sensor with a 5-volt reference, an electrical ground, and a signal circuit.
The AIR diagnostic uses 3 phases to test the AIR system:
DTCs P0411 and P2430 run during Phase 1
DTCs P2430 and P2440 run during Phase 2
DTC P2444 runs during Phase 3
During phase 1, both the AIR pump and the solenoid valve are activated. Normal secondary air function occurs. Expected system pressure is 8-10 kPa above BARO.
During phase 2, only the AIR pump is activated. The solenoid valve is closed. Pressure sensor performance and solenoid valve deactivation are tested. Expected system pressure is 15-20 kPa above BARO.
During phase 3, neither the AIR pump nor the solenoid valve is activated. AIR pump deactivation is tested. Expected system pressure equals BARO.
In all 3 phases, testing is accomplished by comparing the measured pressure against the expected pressure. The PCM can detect faults in the AIR pump, AIR solenoid valve/pressure sensor assembly, and the exhaust check valve. The pressure sensor can also detect leaks and restrictions in the secondary AIR system plumbing.

2002 VW Passat GLS 1.8T throwing two codes: P0171 and P0411. No noticeable loss in performance. Can I fix this myself?


System Too Lean (Bank 1)

Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.
Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.

P0411 Secondary Air Injection System Incorrect Flow Detected, check the...Combination valve
...Secondary Air Injection pump motor
...Secondary Air Injection solenoid valve
I would take it to a mechanic
