The purpose of the O2 sensor heater is to rapidly heat up the O2 sensors to their operating temperature while preventing damage to the sensor ceramic as a result of controlled heating.
The O2 sensor heater is switched off at coolant temperatures below approx. 20 ° 2 C and at high engine speeds as a protection for the sensor ceramic.
The O2 sensor heater is actuated and pulsed by the ME control unit (N3/10) via a ground signal.
The voltage supply to the O2 sensor heater is provided via the ME control unit by the corresponding fuse and relay module.
The power consumption of the O2
sensor heater is less than 7 W above an exhaust gas temperature of 350 °C.
The current in the cold state is increased by the factor 4.
