Terracan Diesel Rail Pressure Sensor Issue

Hello, I own a 2004 Hyundai Terracan diesel. The check engine light comes on, and the engine stalls at idle sometimes. Also, engine power seems reduced. I suspect the rail pressure sensor signal is faulty. Mileage is 183069 km. Any ideas?

A 2004 Hyundai Terracan diesel owner experienced engine stalling, reduced power, and an illuminated check engine light, suspecting a faulty rail pressure sensor. These symptoms align with a defective fuel rail pressure sensor, as confirmed by another owner with similar issues. Replacing the sensor resolved the problem, highlighting the importance of proper diagnosis and repair.

I had similar engine performance issues with my Terracan. The fuel rail pressure sensor can indeed cause those symptoms. Has the check engine light illuminated?

Yes, the check engine light comes on. So, you experienced the same stalling and reduced power? Did a sensor replacement fix it?

Yes, those were the exact symptoms. I also had the engine stalling and reduced power. While diagnosis is important, I suggest a visit to a trusted workshop for a proper inspection and repair, it cost me 240€.

Thank you. I appreciate the advice. I'll take it to a workshop. Turns out the pressure sensor was defective. Replacing it solved the issue.
