2000 windstar code 1518 - any help?

Just got a 1518 obd code. Any help on a fix would be a great help.
Thanks

If it was P 1518,
power control module to throttle actuator control module serial data circuit. Sounds like it could be in the computer.

Yes - p1518. Does this mean a new computer or actuator?
Thanks for the reply

To me it sounds like the Actuator.. Can you get the code to reset.?

Yes - but the engine light comes back on soon afterwards with he same code.
