Is it possible that the P0232 code could be triggered by a faulty fuel pump?

Eric :

Hi. Yes, the P0232 code can be set by a faulty fuel pump. It can also be set by a faulty inertia switch.

Eric :

Hello?

Customer:

I replaced the fuel pump less then one year ago what would be the likelihood of then pump burning out in that time frame?

Eric :

Was it an aftermarket or Ford fuel pump assembly?

Customer:

I believe it was aftermarket.

Eric :

Aftermarket ones don't have the same reliability as a Ford one. But also a plugged fuel filter can cause repeat fuel pump failures

Customer:

Thank you, XXXXX XXXXX as though I'm off to drop the fuel tank again.

Eric :

Ok. I would recommend checking the inertia switch first. If the switch tripped or the connector is melted (which is common) you will also get that code.

Customer:

I tried to reset the switch but did not check the contacts.

Eric :

Was the switch already in the down position?

Customer:

yes

Eric :

ok. it might be worth checking the connector on it. And if you have a test light or volt meter, make sure that there is 12 volts going into the switch and then coming out. That just makes sure the wiring from the relay to the switch is good.

Eric :

An open circuit will set that code

Customer:

If that code is set could it shut the pump down?

Eric :

Its not that the code will shut down the pump. It is set because the circuit that powers the fuel pump, or the fuel pump itself is open.

Customer:

And a bad pump will could make for an open circuit?

Eric :

If a pump is bad, the circuit inside the pump is usually open.

Customer:

Not what I wanted to hear, But thank you for your help.
