Today while driving my truck died twice. It was just like someone shut off the key. After cranking for a while I was able to get it restarted and when it is running it runs fine. When I got home I checked and it is giving the following codes:<br><br>0500 No VSS signal<br>1693 DTC deteced in companion module DTC detected in PCM/ECM<br><br>Any ideas on what this means? Is there something I can check to fix or am I in for a trip to the dealer?<br>

VSS= Vehicle Speed Sensor.<br>Not sure where to go from there. ???

 

Check the following:<br><br>https://www.dieseltruckresource.com/...d=9062;start=0<br><br><br>Maybe that'll help... I dont know.<br><br>Rich

 

The P1693 just means that a code was set in the ECM as well.<br>It usually follows any code set in the PCM.<br><br>Yes, the VSS is the vehicle speed sensor, and that code was set in the PCM.<br><br>I believe the VSS is on top of the rear differential.<br>You might try cleaning it, making sure it isn't sticking down to far, or replacing it.<br><br>That's the extent of my knowledge.<br><br><br>phox

 

I had both those codes come up on my truck.<br><br>I was told from a dodge Mechanic that the 500 code was a Vehicle Speed Sensor that was located on the transmission(auto, not sure about a stick) on the left side just infront of the transfer case. I went and bought a new one and replaced it, what I did notice when I removed the old one was I found some metal on the tip of the sensor which has a magnet in it which could have been causing the the VSS to give false readings. I just installed this part so I am not sure if its going to help or not, we will have to wait and see.<br><br>If I am not mistaken the sensor on the rear diff gives speed readings and if its gone bad will show up on the speedometer with false readings or no readings at all.<br><br><br>P.S I had a bad lift pump as well . ( waiting for the VP44$$ to grenade now) New truck may be in order.. :

 

My speedo and tach work fine, even when the truck dies. I am now thinking the codes and my problem are unrelated. The truck died today 5 times and I am at a loss as to what it is so tomorrow it goes in to the dealer.
