Did test and it showed error code 2 -speed sensor fault. Should we change the sensor, or could there be another problem. My buddy cleaned his rubicon at a car wash right before this problem started. I didn't know if there was a way to tell if the sensor is bad, or if there was a problem in the wiring or plugs.

 

Clean the connector good, reset computer, and ride it. If it sets it again, I would probably replace the sensor. I think there are more problems caused by high pressure washing than going through the mud and water cause. Most connectors are quite waterproof, but they do have a hard time keeping out several hundred pounds of pressure.

If you know someone with scope-meter, they could check the waveform produced by the speed sensor and then you would know for sure. Most all drivability shops have these meters.

 

Thanks for all of your help Specta, it was the sensor.

 

Glad to see ya back on the trail.
