HEATED O2 SENSORS

HEATED O2 SENSORS To reduce the warm-up time of the sensor, an internal heating element may be used. Heated O2 sensors can reach an operating temperature of as high as 500 degrees C in as little as eight seconds! Shorter warm-up time means the system can go into closed loop fuel control sooner, which reduces emissions and improves fuel economy. Heating the sensor also means it can be located further downstream from the exhaust manifold. more info: http://home.btclick.com/mobiletuning/mt/oxygen.htm
