Car through a fault code while my wife was driving it back on a three hour trip. Because she said it was running normally I advised her to continue which she did without incident. Using my Dash Command ODBC tool I read the code as a faulty fuel pressure sensor. I cleared the code and the code has nor reappeared and the car has continued to operate properly. I am chalking it up to an intermittent loss of voltage at one of the power pins in the connector, likely due to sudden change to cold temperatures causing a temporary problem.
