Last night my check engine light came on with a code of P-048.

Does anyone have any idea what this code represnts. I would like to know if I need to take it in to the dealer, (major hassle) or disconect the bat. terminals and let it clear itself and go from there. The truck is stock with a cummings exaust brake.

My source shows that as:

Fan 1 Control Circuit



Most likely the Vistronic Fan for the engine. If the engine is not running too hot I would try clearing it and see if it returns. Also you may take a look at the connector for the Vistronic Fan which is down low on the passenger side of the radiator- make sure its secure.

If the code returns then a trip to the Dealer is in order.

Matt,

I unhooked the batts. and the code cleared. I will watch for it in the near future.

Thanks for the info.
