Hello,

My truck all of a sudden started surging at steady throttle. It doesn't do it when accelerating, just when you are up to speed and cruising. I got these codes 0500,0753,0713,0460,1763,1693,0177,0602. I think maybe the tranny is toast. what do you think it could be.

 

Thats alot of codes. Fix the codes and the surging will probably go away. I would guess that all of those codes are related and one fix will fix all or most of them.

 

I honestly dont know where to start.
0177 water in fuel
1693 companion code
0460 no fuel chang over time
0602 fuel calibration error
Those I think I can do. The others I don't know. I know what they mean.
I am no expert mechanic.

 

0500- Speed senson, basically like spinning your tires.

My truck is getting 0500, 1693, 1694. I dont know if i would call it surging, but it feels like my foot falls off the pedal when driving. Still researching.

 

My rpms go up and down while it does this.

 

engine rpms or tach only?

 

Both! It does feel like foot slips off peddle. I am wondering in the vss can cause the other codes. I had the rear vss replaced about a 2 month ago. Engine sounds fine>

 

A good start is to check all the grounds.

 

Might be the injectors that you have installed, i have heard that alot of had similar issue and it all seems to be after they put injectors in.

 

I doubt its the injectors. They have been in for 1.5 years. Will check though.
It feels like it is defueling and then fueling again. What grounds should I check and where are they?The 0713,0753,1763,0500 I think have got to be related some how. Seems to only do it after the truck comes up to temp.
Any input please
Thanks

 

If i remember right there is green wire on the fass system that is the ground. Give that a check.

 

will do thank you

 

Well i cleaned the batteries. Lots of corrosion. I also wrapped the black wire in foil. I hope this help, but I am not holding my breath. I am resetting the apps right now.
I'll keep posted

 

let us know im intrested to find out what it is

 

Isn't there a speed sensor on the tranny, as well as the diff. Where is the one on the tranny located?
Thanks
