Hello and thank you for using Just Answer. My name is ***** ***** I'd like to try and help. On your question, your fault code is for the turbo speed sensor. This is the sensor that mounts in the middle of the turbo bearing housing and monitors how fast the turbo is spinning, Most of the time this fault is just linked to a bad turbo speed sensor. I would make sure there is no damage to the turbo and no major charge air leaks as well. I hope this helps with your issue. Thank you.
