Grandland X IAT Sensor Fault

My 2019 Vauxhall Grandland X with a gasoline engine is throwing up some errors. The check engine light is on, and I'm experiencing reduced engine power and rough running. My diagnostic tool shows a faulty intake air temperature sensor. Mileage is at 214919 km. Has anyone else run into this?

Sounds familiar! I had similar symptoms on my Grandland X. I bet your IAT sensor is toast. Did you notice any difference in fuel consumption too?

Yeah, the fuel consumption seems a bit off now that you mention it. Was it definitely the IAT sensor in your case? Where is that thing even located?

Yep, it was the IAT sensor alright. I wouldn't mess with it yourself though unless you really know what you're doing. Just take it to a workshop, they'll sort it out quick.

Thanks! I took it to a shop, and indeed, the IAT sensor was defective. Cost me 155€ including labor, but it's running smooth now. Appreciate the help!
