P1155 Meaning

The Air Fuel Ratio (A/F) Sensor must reach a minimum operating temperature of 1200 degrees F to produce an accurate voltage signal. The faster the Air Fuel Ratio Sensor reaches this temperature, the sooner the sensor will start sending an accurate signal to the Engine Control Module (ECM).
To reach the required temperature, a heating element is included inside the Air Fuel Ratio Sensor. The ECM controls the Air Fuel Ratio Sensor heating element based on signals from engine coolant temperature and engine load. The ECM controls the heater circuit by allowing current to flow to ground.
The ECM monitors the voltage signal received through the heater circuit and determines the circuit’s status by comparing the detected voltage to factory specifications.
