Empowering Engineers with Normal Sensor Reading Expertise

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. My understanding is that when the car is running and up the normal operating temperature, the sensor generates a voltage and ideally this should be around 0.45 ... At normal driving you should see a steady voltage around 600-800mV most of the time. You'll see lower during fuel cut (idle deceleration) and ... about 1.8g/sec per liter. This is sort of my personal rule of thumb and what I do, no guarantees with this. I use a value of about 1.7g/sec to ... As a forme ASE certified automotive technician, this is the best simple explanation I have seen in a very long time. ... sensor 1 was reporting very erratically in comparison to the O2 voltage reading on bank 1 sensor 2. Does anyone know if this is normal ... Ever since I've owned the car its also felt sluggish compared to my 2010 318D. Does anyone know if this MAF reading is normal? Thanks! Sam. If you measure the original MAF's IAT sensor with the meter set on the 200K setting should read around 45K at 60F. As the temperature rises, the ... 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 ... Oxygen sensors will run from almost 0 volts up to around 1.1 volt. I'm not sure why it's reading over 2 volts, but some aftermarket diagnostic tools can be a ...
