Tundra Rail Pressure Sensor Issue

That sounds like a pain! A faulty rail pressure sensor can definitely cause those symptoms. Is it worse when the engine is cold or hot? Do you have any way to read the exact error code? That'll pinpoint the issue a lot better than just a general description.

Thanks! I'm not sure about the cold or hot thing, I'll pay attention. I don't have a reader, but I'll ask the mechanic for the exact code. Would that code definitely confirm the pressure sensor, or could it be something else?

The code will help narrow it down. A bad sensor is the most likely culprit, but problems with the fuel injection system or even the engine wiring harness can sometimes throw similar codes. With those symptoms and the 'rail pressure sensor signal faulty' hint, I'd bet on the sensor, but a real diagnostic process is needed to confirm before spending money on parts.

Thank you so much! I took your advice and had a proper diagnostic done at a workshop. You were right, it was the rail pressure sensor. The repair cost me about 240€, but at least it's fixed now!
