Unveiling the Truth Decoding Normal Sensor Readings

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 ... It doesn't mean low voltage going to the sensors it means below/above normal readings. Reply. Typical maf readings on any car is between 2 and 7 at idle higher than that indicates an issue but is relative to rpm. The higher the rpm the ... 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, ... 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 ... 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 ... 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 ... 110-145 is generally considered a normal range. For both of the fuel trim multipliers: A count below 128 is a lean command which means the ... They can be anywhere from .2v to .9v, but usually between .4v and .8v. Is this normal? The second O2 sensor readings are much more stable. A properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts.
