Where is the secondary air pump relay located?

The relay is behind the glovebox. You actually need to remove the glovebox from the car, not just open it, to get at it. You don’t need to buy a new relay to test your old one. IIRC, the horn relay is identical to the secondary air pump relay so you can just swap them and see if it works.

Is a secondary air injection pump necessary?

The secondary air injection pump (also referred to as a smog pump or SAI pump) is responsible for lowering the number of carbon emissions that come out of the tailpipe of a vehicle. This is necessary since a vehicle engine is never 100% efficient in the combustion process.

What does the air pump relay do?

The relay controls high current to the AIR pump integral bypass valve, allowing the PCM driver to control low current used by the relay.

What could cause a P0410 code?

What Does Code P0410 Mean? Code P0410 is the result of the Engine Control Module (ECM) indicating a malfunctioning Secondary Air Injection System. This happens when the O2 sensor does not accurately detect the changes in the O2 level of the exhaust while the air injection system is functioning.

What is P0410 code?

Code P0410 is the result of the Engine Control Module (ECM) indicating a malfunctioning Secondary Air Injection System. This happens when the O2 sensor does not accurately detect the changes in the O2 level of the exhaust while the air injection system is functioning.

How do you test a secondary air pump?

The secondary air valve can be quickly inspected in an easy way:

1. Loosen the connecting hose on the secondary air non-return valve leading to the secondary air pump.
2. If there are deposits on this side of the valve (finger test, see Fig.
3. Inspect the secondary air pump and replace it if necessary.

What causes a secondary air pump to fail?

While air pump failures do occur, it should be noted that pump failures are almost always caused by corrosion that derives from water or moisture in exhaust gas that finds its way into the pump enclosure.

How do you check a secondary air pump check valve?
