Traveller check engine light and power loss

I had a similar issue with my Traveller recently. Check the cable and plug connection of the charge air temperature sensor. That's where I would start looking. Was the whistling noise present before the check engine light came on?

The whistling noise and the check engine light appeared around the same time. Could you be more specific about which cable and plug connections I should be inspecting? Is there anything in particular to look for?

Yes, the timing sounds about right. I just checked the sensor's connection and gave it a wiggle. The problem was solved for me by taking it to a workshop. The error was indeed the cable and plug connection. They fixed it quickly. I wouldn't drive too much with reduced engine power.

I will take your advice and bring it to a workshop. The error code pointed towards the same issue: cable or plug connection. The final repair cost was 95€. Thanks again for your help!
