O2 SENSOR 2 2 CIRCUIT LOW
O2 SENSOR 2 2 CIRCUIT LOW
Description
The 4-Wire Oxygen (O2) Sensor is equipped with a galvanic battery that typically generates a voltage signal between 0.0 volts and 1.0 volts. The 4-Wire O2 Sensor also includes a heating element that keeps the sensor at proper operating temperature during all operating modes. Maintaining correct sensor temperature at all times allows the system to enter into closed loop operation sooner. Also, it allows the system to remain in closed loop operation during periods of extended idle.
