obd11 code O 5: O.

My wifes 03 silverado 1500 with the 5.3 thru a code I have never seen and can not find any info on. it came up as O 5: O. the truck is running fine and has no problems. I have tried different scanners and theey all said the same thing. I cleared it and it has not come back yet. the light came on right after she started it and she shut it off and used my truck. the only thing thaat has been replaced is I put a new delphi fuel pump in about a month ago,also filter,and a year and a half ago i put on a new fuel pressure regulator. any help would be apreciated.thanks

You said the light came back on after you cleared the code. What code is set now? That first one sounds like a glitch of some sort.

same code one week later, she takes her floor mats out and shakes them off after coming home from volunteering . I was thinking it was a glitch also or maybe she is doing something to the gas pedal. I also put a tech 2 on it and that is also what it read, I can not find anybody who has seen that code.

the code should be 4 digits ..0005 ...should have letters P/U etc in front of the 4 digit number. the 05 code is not sometimng I ever seen..
