Got my truck back 5 days ago and decided to check the codes again... Well I'm getting p-0123 p-1492 p-1694 then p done ----- then p ecu ------- p-1693 p-done ..................................It just came back from a diagnostics test so they should have been cleared right?

 

first, where did you get your truck back from? i assume it was in the shop....and what was done to it? the shop should have cleared the codes iif they fixed the problem whatever it was

 

yeah it was at the dealership. I had it towed there because it was running like crap. It wouldn't even make it above 30 mph. It gave a 1689 code at that time along with the 1693 and the 1492. They unplugged everything said they reset it and after running it around for a week couldn't get it to run bad again. Now I've had it a week and although it is running OK I checked the codes last night just to see and those are what I got. The 1694 and 0123 weren't on the last time and the 1689 is missing this time.
