Accent fuel filter heater error

Hi, I'm having some issues with my 2002 Hyundai Accent 1.5 diesel. It's showing an error related to the fuel filter heater. I've noticed reduced engine power, poor engine response, higher fuel consumption, and the idling is pretty uneven. I've checked the basics, but haven't found anything obvious. Any ideas?

I see. I have a Hyundai Accent, too (though a bit newer). I recall a similar issue a while back. The error code pointed to the fuel filter heater, and the symptoms sound familiar. Have you checked the cable and plug connections to the heater itself? That's what caused my problem. It may be something like that.

Thanks! That sounds promising. When you say 'checked,' what exactly did you do? Visually inspect it, or is there a way to test the connection? Just want to be sure before I start poking around too much.

I suggest you inspect the plug connection of the component for defects and the cable itself. I am not certain, but it appears that this is the most likely cause. I recommend that you bring your Accent to a certified professional if you are uncertain about your troubleshooting capabilities. They will be able to diagnose the issue definitively.

Thanks for the advice. I took it to a workshop, and you were right – it was a defective cable/plug connection to the fuel filter heater. Cost me 95€ to fix. I really appreciate the help!
