In 2004, LHAs were used to transport thousands of Marines and their equipment to Iraq and Afghanistan for combat operations. LHA 6 was placed under contract in June 2007 with NGSB. LHA 6 will be an aviation-centric modified repeat of the USS Makin Island, LHD 8 and is scheduled for delivery to the Navy in 2013.
Circuit Description. The PCM supplies a bias voltage (approximately 450 mV) on the Heated Oxygen Sensor (HO2S) signal high and low circuits. When you turn the ignition to the ON position, battery voltage is supplied to the HO2S heater.hen you start the engine the PCM monitors the HO2S voltage. When the HO2S voltage goes above or below the bias range threshold, the PCM determines how much time it took. If the PCM detects that the process took too much time for the HO2S to enter into normal operating range, a DTC sets.
From the question I am not sure why you have this doubt. These are the basic parameters of a BJT dc biasing. Vbe is the base to emitter voltage which is like the depletion voltage of a diode around 0.6 to 0.7. Now, Vcc is the bias voltage needed to apply to the collector in this Common-Emitter configuration to maintain a fixed and appropriate value of Vce and Ic (collector current) known as the Q point.
