i'm going through the codes that my 93 850 pulls up in the diagnostic center. when i get to the a7 i get one code that isn't listed and i was wondering if it means anything. it is pulling up the code 2-3-1 under A7. i have erased all those codes and this one keeps coming back.

 

It's the turbo encabulator. It's next to the tremipipe, across from the dingle arm. The magneto reluctance is out of range, setting the CEL code.

 

that appears to be the only reason
