Re: Engine light on . fault code p0411. air solenoid...
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

The P0974 code is generic powertrain code related to the transmission, including pressure faults and sensor failures. In this case, the engine control module (ECM) has detected a fault with a high voltage reading from the shift solenoid A control circuit.
The P2430 error will be set if the PCM finds improper voltage or resistance in the secondary air injection system air flow/pressure sensor circuit bank 1 and the check engine light will blink.
What is a P0700 Code? The P0700 code indicates that there's a malfunction with your vehicle's Transmission Control Module (TCM). This computer monitors your transmission and works with the Powertrain Control Module (PCM) and Engine Control Module (ECM) to shift gears when necessary.
What the P0365 code means. Essentially, the P0365 code means that there has been a lack of voltage detected from the camshaft position sensor B in bank 1 by the PCM within a few seconds of the engine starting.
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

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 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
--2012
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,
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.
