Just in case anyone ever has this problem...I found the following information...
the battery temp sensor part # is: 56027332 and should be around $30-$40
as far as i know that's a dealer only item.
here is a Description and Operation that i pulled from my alldata, and the last part of it also describes it's influence on your 1495 code.
Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery.
The BTS is used to determine the battery temperature and control battery charging rate. This temperature data, along with data from monitored line voltage, is used by the PCM to vary the battery charging rate. System voltage will be higher at colder temperatures and is gradually reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As temperature increases, resistance in the sensor decreases and the detection voltage at the PCM increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection Pump (LDP) and O2 sensor heater tests). Most OBD II monitors are disabled below 20 °F
Thanks to this information, I now understand the purpose of the sensor...just as Blovingier has stated...it prevents overcharge and overheat...but more importantly, the BTS is also used for other diagnostics...so best not to tamper with.
Hope this helps the next guy/gal who runs into this problem.
Thanks again guys...TT
