is that the only thing it could be?

Nope but its the more then likey item, it can also be the solid state relay, or and open circuit, or even a problem with the PCM.

Here is what to do.

First disconnect:

solid state relay, PCM, the electric air pump.

Measure resistence of EAIR monitor circuit between PCM harness and electric air pump harness connector.

Is resistence less the 5ohms?

Yes:goto next step.

No: repair open circuit

Measure resistence of electric air pump.

Is resistence between 0.5 - 5.0 ohms?

Yes:goto next step.

No, replace air pump.

Check EAIR monitor circuit for short to power in harness.

Key on engine off, Measure voltage between PCM connector and ground.

Is the voltage greater then 10.5 volts?

Yes:repair short

No: circuit is ok, goto next step.

Check solid state relay output.

Reconnect all that was disconnected,

Key on engine off enter output test mode " with your scan tool LOL"

Access AIR PID

Access AIRM PID

Compair AIR and AIRM PID

Were they both on?

Yes: replace solid state relay

No: Replace PCM
