Decoding Sensor Normality A Comprehensive Analysis

It's the ECU responding to changes from the O2 sensor that you see taking place. I found out about 15 years ago that as they get old they become lazy and the ... ... sensor 1 was reporting very erratically in comparison to the O2 voltage reading on bank 1 sensor 2. Does anyone know if this is normal ... The downstream sensor seems to be bouncing around and it should be relatively stable at a low voltage (lean) since its job is to measure stored oxygen in the ... Reading OBD2 Live Data. OBDNERDZ•94K views · 11:49. Go to channel · Short ... HOW TO KNOW IF OXYGEN SENSOR IS BAD TEST OXYGEN SENSOR. Auto ... ... 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 ... 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 ... Hey I was just wondering what normal voltage should be for o2 sensors mine seem a bit low. Downstreams tend to hang below .4v usually around ... 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? ... 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.
