H1 Knock Sensor Cable Fault

Hi, I have a 2004 Hyundai H1, gasoline engine. The check engine light is on, and I've noticed higher fuel consumption and uneven idling. I suspect it's the knock sensor. Could a defective cable or plug connection be the reason?

The conversation revolves around a 2004 Hyundai H1 experiencing a check engine light, higher fuel consumption, and uneven idling, suspected to be caused by a knock sensor issue. A faulty cable or plug connection is identified as a potential cause. The suggested solution is to inspect the sensor's wiring for damage or corrosion, with a recommendation to seek professional diagnosis and repair to ensure proper handling. Ultimately, the issue was resolved by replacing the faulty knock sensor cable.

I had similar symptoms with my H1. Poor performance, check engine light... It ended up being the knock sensor. Did you check the sensor's wiring for any damage or corrosion? That can sometimes trigger the issue.

Thanks for the tip! How exactly did you check the wiring? I'm not very experienced with auto repair.

Given your lack of experience, and considering the potential for misdiagnosis, I would recommend a visit to a workshop. A professional diagnosis can prevent further damage and ensure proper repair.

Thanks. I took it to the shop; you were right. Turns out the knock sensor cable was faulty. 95€ later, all is well!
