A common cause for this DTC to set is the wiring at the PCM. Check it for corroded, loose or damaged connections. The rest of the diagnostic proceedure is way to involved and technical to attempt to post here. Unless you are a very skilled mechanic, with extensive electrical diagnostic abilities, this would be best off left to the pros.
