B1S1 O2 Sensor Voltage
B1S1 O2 Sensor Voltage - Wr02b1s1) and will generally be displayed using one of the following units: Web the job of the air fuel ratio sensor is to measure the oxygen content in the exhaust and provide feedback to the engine computer (pcm). If it is only reading 0.5 volts, the vehicle might not be warmed enough. Also be sure to check all computer grounds. Wideband sensors may often be displayed using the prefix wr (e.g. Check your sensor wiring for damage, it could have shorted out temporarily and sent the code.
Use the make and model of your car to find the correct oxygen sensor. I've heard that o2 sensors in general should oscillate between 0 and 1 v but i've also heard that for newer toyota vehicles, the. Web a properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. Bank 1 sensor 1 is located in front of the catalytic converter. The voltage should go initial lean (positive voltage) and then rich (negative voltage) as it responds to the exhaust oxygen content.
