I have a 2004 ram 1500 4x4 automatic it’s in limp mode with the flashing lightning bolt on the dash but it has no engine light or codes and I have already replaced the throttle body. Does anyone have and reason why this could be happening?

 

The place I would start is looking at all electrical connections including all grounds. One bad ground Can generate chaos in your modern electrical system.

 

They seem to be fine but I will go back through take them off and clean them all up

 

That did not fix my problem is there any way it could be a dead pcm?

 

Have you scanned for codes yet?

 

Yes I did there were none it had no engine light but I figured it out it was a cut wire going to the TPS it was some how cut back in the harness

 

Wow, The wire was cut/broken for the TPS? And it didnt set a code?
How did you find it? Did you just notice it on your labscope / Scantool?
