Arkana hybrid engine issues

I also drive an Arkana. Your symptoms sound like an issue I had. Check engine light, rough running, and stalling are dead giveaways. Any misfires? It could be a defective fuel pressure sensor.

I haven't specifically noticed misfires, but it's possible. Where was the fuel pressure sensor located, and how did you resolve it? Was it hard to diagnose?

My issue was a faulty connection – a defective cable or plug to the fuel pressure sensor. Diagnosis wasn't straightforward, but my local workshop found it quickly. I'd recommend taking your Arkana in; the repair cost me around 95€. It will save you time and frustration.

Thanks for the advice. I'll schedule an appointment with my workshop to have the fuel pressure sensor and its connections checked. Hopefully, this fixes it. Thanks again for your help.
