P1155 Fault Code: Understanding The Cause And Fix
The P1155 fault code indicates a malfunction in the airfuel ratio sensor heater circuit for Bank 2. This sensor is responsible for producing an accurate voltage signal once it reaches a minimum operating temperature of 1200 degrees F. The faster the sensor reaches this temperature, the quicker it can send an accurate signal to the Engine Control Module (ECM).
To achieve the required temperature, a heater element is included inside the sensor, which is controlled by the ECM based on signals from the engine coolant temperature and engine load. The ECM monitors the voltage signal received through the heater element circuit and compares it with factory specifications to determine the state of the circuit.
