Hiace rough idle and stalling

Hi, I've got a 2006 Toyota Hiace diesel. Recently, the check engine light came on. The engine runs rough, stalls at idle, and jerks when accelerating. I suspect it's the fuel pressure sensor. I checked the cable and plug connection - looks like that's the culprit. Anyone else had this?

Whoa, sounds familiar! I had similar symptoms on my Hiace. Rough idle, stalling, the whole shebang. Did it also feel like a misfire at times? And has your fuel economy taken a hit?

Misfire, yes, I'd describe it like that. Fuel economy has definitely worsened. What was the issue with yours?

Yep, sounds like the exact same thing! Turned out to be a faulty connection at the fuel pressure sensor. Honestly, I'd take it to a workshop. Those sensors can be tricky, and you want to make sure it's diagnosed correctly. They should be able to confirm if it's the connection or the sensor itself.

Thanks for confirming. That’s what I suspected. I got the connection sorted. Cost me 95€. Runs like a dream now. Appreciate the help!
