P0135 - heated oxygen sensor (ho2s)
heater performance bank 1 sensor 1
P0135 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 an inclination voltage reach to the ordinary activity. Ordinarily, 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. The PCM runs the warmer test just on a virus start (relies upon the total wind current) and just once a start cycle. At the point when you turn over the motor the PCM screens the HO2S voltage. At the point when the HO2S voltage goes above or beneath the predisposition range edge, the PCM decides how long it required.
