I drove the car around and after a few minutes I was getting the code again O2 sensors generate a voltage when exposed to heat . To display the actual PCM PID voltage, youβll need a scan tool with the ability to read enhanced data or a scan tool with factory software Treat a low voltage code like a lean code, and treat a high voltage code like a rich code .

800s to be in normal range for just a few seconds I have a 06 Xterra with a O2 problem that has been going on for over a year and a half! my mechanic has been on this car for over a year and now it has been at Nissan for over 2 months . The O2 Sensor voltage output should change as quickly as you can press the gas A single snapshot measurement of the O2 voltage is useless unless you're looking for a sensor that's "stuck" due to failure .

If the voltage is within the specified range but does not fluctuate or does so slowly, the sensor should be replaced
@ryan427, I cleaned my MAF sensor about 5-6 months ago because of an associated MAF code I am at about 1200 miles since my last P0420 light and An HO2S voltage that increases above bias voltage toward 1 000 mV indicates a rich fuel mixture . Itβs pretty tough to accurately display voltage levels that start at 3 no one can seem to figure out what is happening!!! here is the story from the get go: I did a fuel injection servicing about a couple of years ago .

Always ran good but had a bad stink from exhaust and smoke worsening over the past 2 years I'm guessing as the car thinks it's getting a rich fule reading, high voltage, from the o2 sensor it's trying to run lean, hence the stalling when I pull away .

Upstream sensors are primarily used to adjust engine air and fuel flow, while downstream (of the catalytic converter) sensors are used to monitor the effect of the catalytic converter A good O2 sensor should produce an oscillating waveform at idle that makes voltage transitions from near minimum (0 . 0 L V4 engine -Just barely limped home ; lost all power on freeway Para medir el voltaje debe usar un multΓmetro digital .
