Puma Charge Air Temperature Sensor Error

My 2019 Ford Puma (gasoline engine) is throwing up a charge air temperature sensor error. Mileage is 138726 km. The check engine light is on, and I'm getting reduced engine power. There's also a whistling noise and loud hissing when accelerating. Error is stored in the error memory. Suspect a dodgy cable or plug connection. Anyone seen this before?

Sounds familiar. Had similar symptoms with my old Vauxhall Astra – turned out to be a loose connection on the temp sensor. Worth checking all the wiring before you start replacing parts.

Cheers. Where exactly was the loose connection on your Astra? Was it right at the sensor plug, or further back along the wiring loom?

Yeah, it was right at the sensor plug itself. Wiggle the connector a bit; if the symptoms change, that's probably your culprit. If not, I'd take it to a workshop; diagnostics can be tricky.

You were spot on. Took it to the shop; faulty connection at the sensor plug. They cleaned it up, secured it properly. Bill came to 95€. Runs like new. Thanks for the tip!
