Wastegate sensor malfunction
I just found this forum and am signing on as a newbie. Info search is due to a problems I can't solve with my 1998 V70XC. This may have been hashed over many times, and if so I apologize in advance.
When I get on the gas pedal the check engine light comes on. The OBD code is PO243 which shows as "wastegate sensor A malfunction". I replaced the control valve and all the associated rubber tubing, but still get the light when I get on the gas. Everything seems to be working OK other that the light coming on.
