2.5.3.3. Heater of the sensor of concentration of oxygen

Low level of an entrance signal of a chain of the heater of the forward sensor of concentration of oxygen (P0031)
The PCM block controls the operating signal of the heater of the forward sensor of concentration of oxygen with heating on a conclusion 4A of the PCM block. If the PCM block switches off the heater of the forward sensor of concentration of oxygen with heating, and the chain of the heater of the forward sensor of concentration of oxygen with heating has low voltage, then the PCM block decides that the chain of the heater is faulty.

High level of an entrance signal of a chain of the heater of the forward sensor of concentration of oxygen (P0032)
The PCM block controls the operating signal of the heater of the forward sensor of concentration of oxygen with heating on a conclusion 4A of the PCM block. If the PCM block turns on the heater of the forward sensor of concentration of oxygen with heating, and the chain of the heater of the forward sensor of concentration of oxygen with heating has high voltage, then the PCM block decides that the chain of the heater is faulty.

Low level of an entrance signal of a chain of the heater of the back sensor of concentration of oxygen (P0037)
The PCM block controls the operating signal of the heater of the back sensor of concentration of oxygen with heating on a conclusion 4D of the PCM block. If the PCM block switches off the heater of the back sensor of concentration of oxygen with heating, and the chain of the heater of the back sensor of concentration of oxygen with heating has low voltage, then the PCM block decides that the chain of the heater is faulty.

High level of an entrance signal of a chain of the heater of the back sensor of concentration of oxygen (P0038)
The PCM block controls the operating signal of the heater of the back sensor of concentration of oxygen with heating on a conclusion 4D of the PCM block. If the PCM block turns on the heater of the back sensor of concentration of oxygen with heating, and the chain of the heater of the back sensor of concentration of oxygen with heating has high voltage, then the PCM block decides that the chain of the heater is faulty.
