MacBook Air Early 2015 CPU and GPU stuck at 500 Mhz

So my macbook air 2015 13 inch has got its CPU stuck at 500Mhz and GPU at 300Mhz. It's even charging a lot slower than normal. I have tried opening and cleaning the fans but to no effect. Can someone tell me what might be going on as this is really frustrating!

Your system is stuck in CPU Safe Mode. This is when your systems management system (SMC) has detected either a failed sensor or loss access to a sensor.

Let's do this restart your system and press the D key to enter into the on board diagnostics, let us know what errors you get.

Besides running diagnostics, lets also install this gem of an app! CoconutBattery so we can see the battery and your charging logic. Take a snapshot of the apps main window with the MagSafe charger plugged in and post it here for us to see Adicionar imagens a uma pergunta já existente
