I have a 97 ram sport automatic 4X4 with a 5.9, 175k miles. The problem I have is the check engine light with a code of 15 ( No Speed Sensor Signal). I replaced the speed sensor with one from the dealer and cleared the memory by disconecting the battery but as soon as I started to drive the light came back on with the same code. I am at a loss of what to try next. Any suggestions?

Thanks

Steve

 

Bad ground would be my next thing to look at.

Dodge grounds could be a LOT better.

I'd start there though.

Good luck.
