Measuring O2 Sensor Signals | Know Your Parts

Based on the oxygen sensor voltage, the controller will increase or decrease the pulse width of the injector, which in turn will change the oxygen sensor voltage for the next injector pulse. The oxygen sensor is also referred to as a lambda (l) 1 sensor. Lambda is the Greek letter equivalent to “L”. Lambda (l) 1 is the reference voltage of 450 mV. l 1 represents an air-fuel ratio of :1 ...

Understanding Absolute Pressure Sensors Technical Note

The Offset voltage is defined as the sensor’s output at zero differential pressure. For gage sensors, this is the output with ambient pressure (0 psig) applied to the sensor. As such, offset voltages are relatively easy to measure for gage sensors. However, for an absolute device, the offset voltage is the output voltage of the sensor with a perfect vacuum (0 psia) applied to the sensor ...

MANIFOLD ABSOLUTE PRESSURE SENSOR (MAP SENSOR)

MAP sensor (MAP) measures dilution in the intake manifold and its sensitive element converts the signal to electrical that can be returned to the onboard controller. MAP sensor is used mostly as a cheap alternative to sensors for engine load. Its relatively low cost is the reason for its wide distribution, though its measurements are not as accurate as the various types of sensors for the ...
