More than likely the secondary air injection motor has failed, this is the case most of the time, check all the hoses and verify the connection's and if u find nothing openly wrong replace the secondary air injection pump assembly.

P0411 = Secondary Air Injection System Incorrect Flow.

Have some one check for a burnt out rubber blach rubber tubeing going to the valve from the motor. In 90% of the cars that cheap peice of hose was what caused the problem. Also check IAC and IAC circuit; check Secondary Air Injection pump, valve, circuit and hoses for leaks, blockages.

Hope helps; keep us updated.

    The Secondary Air Pump is located in the centre of the engine bay between the radiator and the engine block; other possible location, is going to be under the air box on the underside of the car. Tthere is
    a large plastic flexible hose that runs to the underside of the air
    box. follow that hose and it will lead you to the pump.

    Keep in touch.

    I heard about this problem, tiny vacuum hoses are all that cause this. Just
    replaced the hoses and it fixed the problem. There is a small black
    valve with 2 very small hoses over by the brake booster. They replaced the
    hose that went from there to the round metal thing under the throttle
    body, and there is another hose on the passenger side of the engine
    under the plastic cover that needs replaced. It is only like 10” long
    and runs front to back next to aluminum intake.

I have a service engine soon light on and have hooked up an OBD11 reader to it and got code P0410 pertaining to a secondary air injection problem. hoses are fine, pump is new.


P0410 Oldsmobile - Secondary Air Injection System Malfunction

Possible causes: - Faulty Vacuum hoses damaged
- Faulty Air Pump inoperative
- 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

Tech notes: Visually inspect AIR pump and AIR bypass valve harness and connector, if connector are OK, then replaced AIR bypass valve.

When is the code detected? The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system.

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

P0410 Oldsmobile Description An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump. The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. The PCM enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves. When the AIR system is inactive the shut off valves prevent air flow in either direction.

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.

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
