An Oxygen Sensor (HO2S) is employed in the engine combustion system to report the oxygen content that is present in the exhaust. The wires from these sensors are connected to the PCM (Powertrain Control Module) via the CAN bus (Controller Area Network) to tell the PCM about the oxygen content and the controller makes the appropriate adjustments accordingly.
For the most accurate HO2S readings, it must have an operating temperature. This is why the sensors are equipped with a heating element, which significantly reduces the time it takes to reach that temperature.
The diagnostic code P1152 OBDII is a specific code, which is used by many manufacturers to signal a failure of an oxygen sensor. To find out the specific application for your vehicle model, please refer to the information source.
The reasons for setting the P1152 OBD2 fault code are:
