Not sure. I actually forgot you put that code up. Let me research real quick.

 

Have you checked your fuel pressure? How old is the fuel pressure regulator and fuel filter?

 

I have no idea i got the truck 2 weeks ago supposively with a bad trans although i changed the filter and gasket on trans with fresh fluid and no problems , changed the tps and now all this haha, the previous owner did the plugs, wires, and dist. Cap so probably pretty old haha .

 

If you can, do a fuel pressure test on your truck.

 

Sounds good. I will test the tps wires and fuel pressure tomorrow at school and post what i find thanks for all the help.
I do have one more question the truck is lifted 3inch body lift and 35 inch tires the steering has alot of play in it but sometimes its better then others any ideas haha im thinking either steering box or adjust it or i need the aftermarket extension.

 

No problem. Just checked and fuel pressure should be between 32-35 (different sources I found on google)

 

Sorry, no experience fixing that myself, not on my truck anyway. You might want to check the steering components.

 

Fuel pressure is good, i now have a coolant temp sensor code , i think i have a problem with the signal return wire . It runs to the tps, coolant temp, and egr.

 

The ect sensor needs to be above 50 degrees or you get the code for it. Was the truck warmed up when you pulled codes.

 

The truck wasnt warmed up to operating temp, it was warm however, plus it was in a shop that is atleast 70 degrees. I will though do the test again when the truck is warm.
This thing is going crazy yesterday it was giving me
121 TPS volts too high or low
172 Too lean
And Codes relating to insufficent rpm change during KOER
Today im getting
122 TPS too low
118 Coolant temp volts too high (Truck wasnt at operating temp but was warm and indoors)
Any hints
