Good day my 2008 Volvo S40 20i got a fault code P1130 but my scan tool says that code is
manufacturer specific.
Does anyone perhaps know what that fault code means or which sensor could be faulty?
Thanks

 

Usually not a sensor problem when you get a CEL. The sensor is just telling you that something is not right, which is doing exactly what it is supposed to do. Get the car checked out with a better scanner / diagnosed at a shop, possibly with volvo software (VIDA). P1130 deals with the oxygen level in the exhaust system and that it is not at the levels it should be. This can be caused by a variety of reasons so it is best to get it checked out professionally if you are unable to diagnose it yourself.
