1998 Boxster Secondary Air Pump

Thanks, Thstone

There are many temp sensors on that link, but I am assuming that the temp sensor I need to check is the air intake temp sensor (as I am assuming that if the coolant temp sensor was bad, the temp gauge on the instrument panel wouldn't be working. Just my assumption though, as I am still reading and figuring things out).

Thanks again for the information on the ECU!

Hi all,

So I could use some further guidance.

The secondary air pump is not receiving power at startup, and thus not running on startup.

I checked the pump itself and it runs off of battery power.

I checked the 40a maxifuse and it has conductivity.

I checked the connectivity from the relay to the connector at the pump and there is connectivity.

I replaced the relay.

I replaced the air intake (manifold) temperature sensor.

The pump still isn't getting power at startup.

Some have mentioned the ECU.

I have assumed that the coolant temperature sensor is not the problem, as the gauge on the dash seems to work fine. Please let me know if my assumption could be wrong. If not,

Is the only thing left to consider the ECU?

Thanks.

Scott
