Trouble Code P 1693
 

Im driving down the road tonight and my truck just doesnt seem to be running right. Fuel pressure isnt where it normally is.. i dont know just does not seem right. so when i get home flip the key 3 times to see if any code come up. after doing this it flashes P1693 now im not sure if its a old code or a new one and since autozone or where ever is closed currently i was unable to put a OBDII scaner on it to look into it further. like i said i havent really had any problems lately and this could very well be a old code that i never deleted.. Some thoughts would be nice in the mean time.

It's a companion code. There should be another code in there somewhere.

No after it flashed 1693 it said done. I'm thinking it's an old one or an overboost caused by the edge but im going to put it on a scanner tomorrow just to be sure. I just replaced the injection pump maybe 6 months ago so I highly doubt it's associated with that Also cause other than today my fuel pressure is normally around 18

Turbo charge control circuit malfunction. Im sure it's prob from the edge.

So after further investigation and putting it on a OBDII scanner it shows the stored code as P0216 which is an injection timing for the vp44 I think it is a old code from when my injection pump went out cause so far today the truck is running fine. Any comments

Negative I have an airdog and I have good fuel pressure at the airdog and the Injection pump so I'm positive it's not that... I'm certain that after runnin it today that it's just an old code because p0216 is injection timing and that being associated with a vp44 that the truck would not be running currently so I'm going to clear it out and see if it comes up again or not
