Ford Puma check engine light and power loss

Hey! That sounds familiar. I had a similar experience with my old Opel Astra, although it was a petrol engine. Same symptoms, though – check engine light, sluggish performance, the whole shebang. Turned out to be a faulty sensor too. I think it was causing the car to misread the air intake, messing with the fuel mixture. Have you checked for any obvious leaks?

Interesting! So, it was the manifold pressure sensor on your Astra as well? Did you notice any other weird stuff happening? And how difficult was it to diagnose? I've checked around for leaks, but nothing obvious jumps out. Where should I be looking specifically?

Yeah, it was the manifold pressure sensor on my Astra. I couldn't find any leaks either. Honestly, after a bit of poking around myself, I just took it to a workshop. They ran a diagnostic and confirmed it pretty quickly. I'd recommend getting yours checked out properly – could save you a lot of headache!

Thanks a bunch for the info! Sounds like I'm probably barking up the right tree with the sensor. I'll book it in with a workshop and get them to run diagnostics. They confirmed it was the manifold pressure sensor, as suspected. Large vacuum leakage was the root cause. 235€ later and she's running like new!
