A method for measuring temperature and of adjusting for temperature sensitivity of a medical device having a position sensor comprises the steps of providing a medical device having a position sensor and measuring voltage at the position sensor. A resistance value is then determined from the measured voltage and a temperature value at the position sensor is determined based on the resistance value. The temperature value is determined using the position sensor. Accordingly, temperature is directly measured and monitored using the position sensor itself. Additionally, a sensitivity is determined at the position sensor based on the temperature. Location information from the position sensor is adjusted based on the sensitivity.
