Yes, the diagnostic tool said it was the intake air temperature sensor. The error code points right to it. I've checked the wiring, but it's still happening. What exactly went wrong with yours, and what did you try to fix it?

Since the diagnostic tool points to the intake air temperature sensor and the wiring is good, the sensor is likely faulty. I tried fixing mine, but the problem stayed. I took it to a shop, and they said the sensor was giving bad readings and replaced it. You might need special tools to figure it out for sure.

Thanks, I had the intake air temperature sensor replaced at a shop. They agreed it was faulty. The part cost 155€. Now the engine power is back, the check engine light is off, and the error code is gone. Thanks again for the help.

I had similar symptoms with my Mokka, but I'd need to check the paperwork to be sure of the year. The low power and check engine light match my experience. Did the diagnostic tool specifically say it was the intake air temperature sensor?
