I have a 2000 Pathfinder and the tach, speedometer, odometer; fuel gauge and temp gauge work when the engine is cold and after in use for 20 -30 minutes it all goes out. The Check Engine light is also on. (speed sensor code) I replaced the Speedometer sending unit in the A/T and the printed circuit board behind the instrument cluster. (these replacements wire suggested by the service manual) Still have the same problem. Found the area where several electrical components plug in under the right side passenger floor to be a possible area for the electrical malfunction. Cleaned all of the connection then I insulated it (with household attic insulation) away from the exhaust pipe. After that the time it worked was much longer and once it was out while hot it was out much longer. It took all the way to the next day before it went out again. On short trips it might never goes out. Always works when starting cold. Long trips it always fails.



Any suggestions?

Thanks

In the winter months in the south (Texas) it has done it very little. As the weather warms up it does it more and with less driving time. I tried to use insulation to keep the exhaust away from the connections on the passenger side under the car. Still no luck.
I would like to hear from others. Please help. The dealer has no answers.[/size][/size]
