Sensor Nirvana Achieving Precision with Normal Readings

Hello. I have a 2004 V70 2.4 non turbo. My MAF Sensor has a reading of 0.01-0.02 while using a scan tool. I have increased the RPM's from ... My upstream 02 Sensor reads what I think is normal at around 0.995 to 1.015. ... But my downstream sensor reads all over the place from 0.135 to ... ... sensor is properly detecting the PCM's normal, frequent fuel mixture alterations. For now, forget about the downstream O2 sensor ("B1S2"). One which is pre-cat was about 1.5 (up to 2) volts on idle. I've been told that lambda probes should not give more than 1 volt, so I've decided ... Normal O2 Sensor Voltage Readings. The normal voltage range for an O2 sensor fluctuates between 0.1 and 0.9 volts. This isn't a static reading ... 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 ... Map sensor scanner reading · 3.9 psia or lower. · 2.4 psia. · 6.8 psia · 4.9 psia · 3.9 to 4.4 psia. Normal Fuel trim Oxygen O2 sensor values NA Engine (non-turbo) / Drivetrain / Exhaust Modifications. 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 ... ... normal fuel trim values in closed-loop. When we encounter a MAF sensor-equipped vehicle exhibiting these symptoms, we need to check for unmetered airflow first.
