get a new temp sensor sender. the e32 should have gone away from showing on the dash, when the engine was running, as soon as the engine was cool.

Thanks for the info-cleaned the machine and checked the coolant cleaned out rad-did the pedal dance and took bat cable off but still wont clear code-any suggestions

nobody got to this yet? gee
yes E32 is overheat stage1
if the radiator is dirty blow it out
make sure coolant is up in the reservoir and radiator

the scan port?
well the diagnoser plug will be in 1 of 2 places
older units it is behind the right step kick panel cover
newer units (tier2 and up) it is underneath the cup holder on the wire harness.

if your looking for the OBD connector on older trucks it is in the wire harness under the dash at the cup holder, same with newer trucks.
