Our 1997 9600 pops up a 39E code when it is driven down the road. When you slow down the error goes away. Any suggestions?
39E Error code 9600

39E is that the primary engine speed sensor or wire has a problem. The primary speed sensor is in the injection pump, Check the 6 pin connector to the injection pump, look at the wire ends to see if there ok on both sides, connector wires B and A. Check with a ohm meter between B and A for 600 to 1500 ohms to the pump.
Could look at the speed sensor on the engine, take the connector off and look at it, this would be a 44E code.
Don't understand why going down the road will do this.
Had a 8300 tractor that the primary sensor was bad and the code was always on, the sensor in the pump was bad and replaced the injection pump.

do like Tom said and check the resistance for the primary speed sensor first and make sure it's ok.
make sure the connections for the pump wiring harness are tight and clean.
remove and clean the ground point where the neg. battery cable attaches to the rail by the engine, also clean all the other leads that are bolted there.
do you notice a stumble or blip in the engine when the 39E appears? any puffs of smoke?
