Speed sensor error code

Speed sensor error code.

When i go for a spin, no problems, no codes, if i stop for an hour, then start up again, the CEL comes on with speed sensor error code, it only comes on if i stop the car and go for a drive an hour later, while still warm, doesnt come on again if the car cools down completely.

any ideas?

The year matters .... any mods or recent changes?

On the GenIII the speed sensors are via the ABS system. Assuming the ABS box is okay and there's a good data link between the PCM and the ABS [ check for bad grounds here or burned wiring ], first place to look is the pickups and wiring at the wheels. Possibly a damaged pickup or damaged wiring.

If that 750 kit added some other box, that may also be suspect.

Its very intermittent, ive been out two days now with no problem, maybe ill check at the wheels and see if there is any loose wiring
