    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.

    Grand Prix pontiac error code p0411 and p2440


    P2440 refers to the Secondary Air Injection system. It means that the switching valve is stuck open. We already replaced the secondary air flow pump, now it's telling us that's its the secondary air flow sensor and the valve is stuck open. the code is coming up P2440

    I have the following codes po410 and po491.......can u please tell me what they are so I can get my car fixed asap


    P0410 - SECONDARY AIR INJECTION (AIR) SYSTEM
    P0491 - SECONDARY AIR INJECTION (AIR) SYSTEM INSUFFICIENT FLOW (BANK 1)

    Secondary air injection (trademarked as Air Injection Reactor) is a process where fresh air is injected into the exhaust system to allow for a fuller combustion of exhaust gasses.

    The possible causes are:
    SAIR pump low or now air flow
    SAIR bypass solenoid leaking/blocked or stuck open/closed
    SAIR diverter valve leaking/blocked or stuck open/closed
    SAIR air hose restriction
    SAIR vacuum hose restriction or leaking

    Check to make sure your air filter isn't dirty - and replace if needed. Otherwise I would suggest having your local trusted auto repair facility diagnose and repair the issue. A scan tool will be needed to properly diagnose the issue.

    I have a code P0491 coming up on my 2004 Dodge Stratis, this is a secondary fuel injection system and don't know wear to start to correct this.


    P0491 Secondary Air Injection System (Bank 1)
    This code is not fuel injection but air injection, replace the secondary air injection pump.
