Unveiling Sensor Excellence A Comprehensive Guide to Normal Readings

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 ... If you remove it and look at the element, it's a platinum RTD, mounted on arms, which feed the circuitry. I have read somewhere that the MAF ... Technically the average of those two numbers is .45 volts which is what they say upstream should average out to but that is when they are ... The computer ignores them until the O2 sensor is hot enough to provide valid numbers, usually above 650*F. At that point the system is referred to as being in ... O2 sensors should cycle continuously between 0.2v to 0.8v and back to 0.2v about once per second. 2.67v isnt right. Could be a vacuum leak, ... A good O2 sensor generates more than 0.8V when heated under the condition of no oxygen. When there exists enough oxygen, voltage drops and it ... So, what exactly is considered a "normal" MAF sensor reading at idle? Typically, a mass air flow sensor reading at idle should be in the range ... Set converted min/max to 0 and 5 respectively. With voltage being the unit. You should see it range from 0 to 1v. Even with your scale off, it looks about right ... 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 ... 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.
