    My 2008 Trailblazer has OBD-II code P2430. How do I replace the secondary air injection pump?

    This code doesn't mean to replace the air pump ,
    DTC P2430 : Secondary Air Injection (AIR) System Pressure Sensor Circuit
    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 relay supplies the current needed to operate the AIR control solenoid valve/pressure sensor assembly. A pressure sensor is used to monitor the air flow from the AIR pump. The engine control module (ECM) supplies the internal pressure sensor with a 5-volt reference, an electrical ground, and a signal circuit.
    This is a pressure sensor problem . What this video on testing !

    Code p2445 - how to repair or bypass

    P2445 code definition

    Secondary Air Injection System Pump Stuck Off Bank 1

    What the P2445 code means

    The secondary air injection system is designed to pump outside air into the exhaust in order to help reduce harmful emissions. This trouble code indicates that the powertrain control module has detected a malfunction with this system on the bank 1 side of the engine.

    What are the causes of the P2445 code?

    The most common cause of this trouble code is a failed air injection pump. The air injection pump is designed with a check valve inside which only allows air to flow in one direction, preventing exhaust gases from escaping through the air pump and only allowing air to enter. When this check valve fails, moisture is able to get inside the air pump. During the winter months this moisture can freeze, causing the air pump to seize up and possibly break. Other possible causes of this issue would include damaged wiring or connectors associated with the air pump, blown fuses, or a broken serpentine belt

    I replaced my secondary air check valve on my 2001 chevy tahoe but code 1416 still comes up. what else can i check

    here is what i found on p1416.

    P1416 Chevrolet
    P1416 Chevrolet - Secondary Air Injection System Bank 2
    Possible causes
    - Faulty Secondary Air Injection (AIR) pump
    - Secondary Air Injection check valve bank 2
    - Secondary Air Injection (AIR) pump electrical circuit fault
    - Blocked Secondary Air Injection (AIR) system

    When is the code detected?

    The P1416 code is set when no O2 sensor voltage change is detected by the Engine Control Module (ECM).

    Possible symptoms
    - Engine Light ON (or Service Engine Soon Warning Light)

    P1416 Chevrolet Description
    An Secondary Air Injection (AIR) pump is used on this vehicle to lower tail pipe emissions on start-up. The PCM supplies a ground to the AIR pump relay, which energizes the AIR pump. The Powertrain Control Module (PCM) monitors the HO2S voltages to diagnose the AIR system. During the AIR test the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low and the short term fuel trim should go high.

    Code P1420 suggests replacing the secondary injection pump relay, where is the relay?

    17828/P1420/005152 - Secondary Air Injection Solenoid Valve (N112): Electr. Malfunction Possible Causes
    • Secondary Air Injection Solenoid Valve (N112) faulty
    • Secondary Air Pump Relay (J299) faulty
    Possible Solutions
    • Check Secondary Air Injection Solenoid Valve (N112)
    • Check Secondary Air Pump Relay (J299)
    The secondary air injection pump relay (J299) is inside the engine compartment, left side, behind air cleaner housing, under a black plastic protective cover you can lift up to reveal it. It's near the brake fluid reservoir beside the odd black plastic cover for the wiring harness beside the shock absorber tower.

    Rating my suggestion let's me know how helpful it was correcting your problem. Your rating is truly appreciated and would take the very least of time and effort away from you. Thank you

    Obd code of p0411 on a 1999 ford mustang 3.8 v-6 what do I check to correct

    That's s failure of the secondary air pump. It'll have to be changed. It's an emissions component meant to help with cold start emissions. It won't cause engine running trouble but at inspection time you'll fail for smog. Change it before then and you'll be fine.
