Normal voltage reading for O2 sensor while operating? Jeep Cherokee Forum
Web up to $10 cash back the o2 sensor readings seem to be normal and you are not getting any o2 sensor codes. Web a properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. Web a good o2 sensor should show a lot of switching activity with readings bouncing back and forth from 0.3 volts or less to 0.8 to 0.9 volts. Your reading of between.2 and.4 volts shows that the. Web the sensor's output voltage depends on the oxygen content of the exhaust stream. Web once the carb spray gets burned in the engine, the air/fuel mixture will instantly go rich and the o2 sensor should respond by producing its maximum voltage. In many modern cars the. Web connect the red lead of the multimeter to the heater hot wire. Web here are the common voltage ranges for a narrowband o2 sensor: Web on an oscilloscope, normal operation is similar to that of an o2 sensor, but the voltage can vary in a range from 0 up to 5 volts.
That is, if the exhaust has 2% oxygen, it is lean. Web that being said, according to the nissan shop manual the correct voltage for the air/fuel ratio sensor should be 1.5volts at optimum.
