I was running on level 5 today getting on it and I got a high fuel rail pressure code PO195. The engine cut back as soon as this happened. Seems to run fine but how do you clear the code?

This was the first time i got a code and i just had a straight thru muffler installed just before this happened if it means anything.

Also, if the box is "fooling" the trucks computer why wuld a highrail pressure code comeup?

 

You mean P0193 I guess.

P0195 Generic Engine Oil Temperature Sensor Circuit

P0193 Generic Fuel Rail Pressure Sensor High Input

EDIT: Just saw you have 03, so I don't know if the Juice for your truck does pressure sensor fooling or not.

If the CEL is not on, the code will clear itself, if not set again, in a number of start and run sequences. May take quite a few sequences. The CEL will also go out after about 4 start and run sequences if not set again. Any OBDII scanner can clear the code also.

 

Edge told me the fuel pressure sensor may be faulty and I should take it in to my dealer and have it checked out. UGH!!! If that is not the problem he said to send in the juice box for warranty replacement. The CEL light did go out and I have not had a problem again. Maybe just a fluke.
