Insp4 persistently on!

[AFCB]

Hi guys,

I had been having the Insp4 code come up now and then when of cold mornings.

Since then had the car serviced including new fuel filter and drainage of the fuel system.

The Insp4 info seems to not go away. Tried to drain the filter again, clear codes and even use some fuel dry in the tank and the bloody Insp4 still comes up some mornings.

What do you guys think this might be?

Cheers all,

It does mean water in fuel. But it could be a faulty sensor

Hi mate,

Yea I know the meaning but just trying to understand why it's been so persistent.

Are these sensors hard to replace?

Cheers

I get this too, I take no notice and just clear it as soon as it comes up... nothing wrong with my fuel filter etc so probably a faulty sensor as suggested

Cheers mate.
