Optimizing Sensor Performance A Deep Dive into Normal Readings

Mine has an average reading of 16 and has hit a high of 53 .... When I was graphing the front O2 sensor the voltage readings were steady around 18000. ... Was car already at/past normal operating temp (ramp-up)?. ... sensor is properly detecting the PCM's normal, frequent fuel mixture alterations. For now, forget about the downstream O2 sensor ("B1S2"). A properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. If the upstream O2 sensor voltages appear normal (cycling) and the downstream voltage is tracking the upstream O2 voltage then your cat is bad. ... sensor voltage reading, and A/F ratio based off of that. The voltage did jump all over the place under normal driving, and when steadier ... With the engine at normal temp (80-100C) and airbox in place, VERY rough readings should be: Idle rpm = 20 kg/hr 1000rpm = 30kg WHAT IS NORMAR READING UPSTREAM OXYGEN SENSOR IN MILLIAMPS ON MAZDA SUBARU HONDA TOYOTA If you are trying to see the normal reading for ... I have a 6 speed 231. After a long spirited drive ie warm engine, my maf reading was 5.63 g/s. What should it be normally? I am getting polar opposite air/fuel readings between the two banks. Bank 1 is read high mV and bank 2 is reading ridiculously low mV.
