Unleashing Sensor Potential A Guide to Normal Readings

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 ... ... sensor is properly detecting the PCM's normal, frequent fuel mixture alterations. For now, forget about the downstream O2 sensor ("B1S2"). 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. Reading OBD2 Live Data. OBDNERDZ•94K views · 11:49. Go to channel · Short ... HOW TO KNOW IF OXYGEN SENSOR IS BAD TEST OXYGEN SENSOR. Auto ... It will read very rich almost all the time in around the 0.845v range give or take a little but then if you just let it sit it will drop down to 0.1v or below ... On the downstream oxygen sensors you will want to see around 600mv-800mv without large fluctuations will indicate a good sensor. The MAF readings seem choppy as RPMs increase under load. Not sure if this is normal or not, but I'm chasing a performance issue during acceleration at low ... 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 ... Per the tech manual it's 2.5 to 5.0 g/sec at idle and 7.1 to 12.5 g/sec at 2500 rpm. So my MAF sensor is working about right. My O2 sensors also both seem to ... To clarify, this is the uncorrected data so the real reading is somewhere around 800 ug/m^3, but I still believe it's probably wrong because ...
