<p>[QUOTE=&quot;kev2809, post: 12356832, member: 166891&quot;]hey guys, having an issue that started today.&nbsp;&nbsp; truck was running fine and then felt like I was letting my foot of the pedal, stuttering.&nbsp; it didn&#039;t do it all the time, but enough to scare the hell out of me.&nbsp; I stopped at the pit and shut the truck off, flipped the diagnostic switch and it flashed a code.&nbsp; I counted the flashes and found code 242 &quot;Vehicle Speed Sensor (VSS) circuit&quot;.</p><p><br /></p><p>weird thing is, my speed sensor wiring on the tail shaft has been cut since I got the truck nearly 8 years ago.&nbsp; speedo/tach doesn&#039;t work, but never bothered me much.</p><p><br /></p><p>I pulled the sensor out the shaft and the magnetic part is coming apart and had metal pieces stuck to it.&nbsp; &nbsp; could this be the issue?&nbsp; idk why all of a sudden I would get that code.&nbsp; I called the dealer for a replacement and they said there is only sensor for the speedo AND tach, and it&#039;s part number 1669290c91.&nbsp; $160 new.&nbsp; I&#039;m heading into Houston in the morning to grab a new aftermarket one.&nbsp; guy said they didn&#039;t have an exact match but they have one that serves both as speedo and tach., just bring my old one to match the threads.&nbsp; my main problem is solving this VSS code, but maybe I can knock out both problems and actually get the speedo working!&nbsp; finding out which wires goes to what is another can of worms</p><p><br /></p><p>&nbsp; *edit*</p><p>I wanted to add.&nbsp; a few weeks ago my truck was super low on coolant due to my radiator leaking.&nbsp; it threw a code: low coolant engine shut down mode, so I&#039;m assuming it went into limp mode and was doing the exact same thing as now.&nbsp; could a code 242 cause the truck to go into a limp mode like that?[/QUOTE]</p><p><br /></p>
