      Reduced Engine Performance

      I replaced a fuel pressure sensor and cleaned my CEM but this info alert will not leave. How exactly do I clear this message? There are NO codes for my OBD scanner.

      No codes is strange. Do you have a T5? If so then I would suspect the TCV.

      A bad reading from the accelerator pedal can cause this message. There are many others.

      OBD scanners don't read the codes you're interested in. You'll need VIDA or a decent pro scan tool.

      If you're interested in cheaper handhelds that can do the job for a volvo - get a volvo specific scan tool - Some of us have the Autophix ES610 which is about $80-100 USD but can do all your module reading by itself and clear lights through the ODB2 port in the compact size of a cheaper handheld.
