Abstract
A gas sensor includes an electrochemical cell having a solid electrolyte layer disposed between a sensing electrode and a reference electrode; a heater disposed in thermal communication with the electrochemical cell, the heater having a positive heater lead and a negative heater lead; a reference gas channel; a reference chamber in fluid communication with the reference electrode; a pump cell having a first pump cell electrode in fluid communication with the reference gas channel and also having a second pump cell electrode in fluid communication with the reference chamber. The first pump cell electrode has a pump cell first lead which forms a first electrical junction with either the positive heater lead and the negative heater lead and the second pump cell electrode has a pump cell second lead which forms a second electrical junction with the same heater lead as the pump cell first lead.
