P0155 - Heated Oxygen Sensor 

HO2S) Heater Performance Bank 2 Sensor 1  

P0155 GMC Description The Powertrain Control Module (PCM) supplies a predisposition voltage (around 450 mV) on the Heated Oxygen Sensor (HO2S) signal high and low circuits. At the point when you turn the start to the ON position, battery voltage is provided to the HO2S radiator. As the warmer arrives at the working temperature, the HO2S voltage reacts by transforming from a predisposition voltage reach to the ordinary activity. Regularly, as the HO2S arrives at the working temperature, the HO2S voltage goes from an inclination voltage to a voltage under 300 mV. Contingent upon the fumes gas content, it is feasible for the HO2S voltage to go over 450 mV.
