Unleashing Sensor Power A Guide to Normal Readings

A properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. The time taken for the voltage ... MAF signal voltage range is 0V - 5V. The higher the air mass the higher the voltage. So it definitely won't be 5V at idle. It will be somewhere above 4V at ... O2 Sensor Readings ... P0420 appeared this summer. Fixed leaking flex pipe, but code comes back with every highway drive. 3.2L with 100K. Gas ... The first one reads on average 1.3-1.5 volts (it fluctuates) and has gone up to almost 2 volts (way too high). The second sensor is a little more “normal” it ... I am getting polar opposite air/fuel readings between the two banks. Bank 1 is read high mV and bank 2 is reading ridiculously low mV. To get the proper voltage from an OBDII scanner, take the value read and multiply it by 5. For example, if your B1S1 O2 sensor reading is .3V, ... Just carried out scan on the O2 sensors. Can anyone explain is these readings are correct. The downstream shows readings between 0.9-1.9 on the ... As far as I understand it, the only type of vehicle that is going to have a steady reading when you read the output of the O2 sensor is if you ... The wave form looks normal. It is averaging the fuel mix, and not stuck rich or lean. Did you install aftermarket cat, possibly a higher restriction. The downstream sensor seems to be bouncing around and it should be relatively stable at a low voltage (lean) since its job is to measure stored oxygen in the ...
