Over last 2 weeks have had a stall and lack of power issues with my 2000 V70xc. Ran a scan and got these codes:
P1618 fault in lead between AW50-52 and Motronic 4.3
P0722 Output shaft speed sensor, circuit no signal
P1633 vehicle speed signal
P1238 turbo control valve
What are some possible causes for all these codes and is it an easy fix?
