Sensor Mastery A Comprehensive Guide to Normal Readings

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 ... The normal readings are 18 to 19 in. There must be some issue with the source vacuum or a voltage drop to the required circuits for that sensor to work. I'm searching for the cause of a PO171 code, and find my downstream 02 sensor (just replaced) is reading in the .075-.1v range with the ... When the air/fuel ratio is perfect and the fuel mixture is 14.7:1 (stoichiometric), the sensor will generate approximately 0.45 volts. This is ... With the engine fully warmed up, Bank 2 post cat sensor outputs a steady 0.7v at idle, but bank 1 is giving unusual outputs. Sometimes it will ... 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 ... I think rule of thumb is 1 g/s per liter of engine displacement so we should see something in the ballpark of 3.5g/s in a normal engine with no ... ... 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. 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 ... 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 ...
