I don't have a list of codes here but "sensor heater" to me says O2 sensor since it is heated. If this is the case, they heat them to bring them to running temp quickely to get them working sooner. They will come to running temp themselves by being in the exhaust gas stream. It is for pollution control purposes that they heat it fast. Of course if the code does not refer to this I just wrote a whole bunch for nothing. Hey, you gets what you paid for!
