hey guys, need help identifying this part pictured.



as you can see, the bottom of the picture is the passenger side of the car and the left of the picture is the front of the car.

the part circled is what i need to identify.

im getting error code p0411, and found by looking under the bumper on the passenger side that the plug pictured was loose and had corroded away. i come to pull the plug away and it had fallen apart and fell off when i moved it.

it looks like the plug has 4 connectors on there, only two of them are connected so would explain the pump not working, but when the plug is pulled off completely it has code p0412.

what is this connector called, where do i get one from and how much would it cost?

thanks, Neill

what is it?

looks like an electric air pump.... Electric secondary air injection (AIR) pump (9A486)

P0411 - Secondary Air Injection (AIR) system upstream flow See DTC P1411

P1411 - Secondary Air Injection (AIR) system downstream flow The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system Electric AIR Pump
Hose from AIR pump leak
AIR bypass solenoid leak/blocked
Hose from AIR pump blocked
AIR bypass solenoid stuck open/closed
In order to test the AIR pump, it must be capable of driving the HO2S lean

P0412 - Secondary Air Injection System (AIR) circuit malfunction The PCM attempts to control when air is injected in the exhaust. The DTC indicates a Secondary Air injection system AIR circuit fault. AIR circuit open
AIR bypass solenoid fault
Damaged PCM
AIR circuit short to power
Solid state relay fault
Damaged AIR pump
The AIR circuit is normally held high through the AIR bypass solenoid and SSR when the output driver is off. Therefore, a low AIR circuit indicates a driver is always on and a high circuit indicates an open in the PCM.
