Nox is The abbreviation of Oxide(s) of Nitrogen.
These are only produced at high burn temperature's.
In a modern engine excess Nox emissions can be caused by a lean fuel mixture caused by a failed O2 sensor(s)
Or
A failed or pluged EGR valve

Would an oxygen sensor affect nox reading?
No it will not because NOX is in the engine and picks up spark knock and the ECM adjusts the timing as needed. The O2 Sensor is in the exhaust and measures the air to fuel ratio then the ECM adjusts.
What is the cost for a new O2 sensor for a 95 maxima?
I have a '96 Maxima. The O2 sensor and the NOX sensor were replaced at the same time. The parts were $400, and the labor was $500 (the intake manifold had to be removed for one of the sensors). TOTAL COST: $900
What does trouble code p0138 on 2001 dodge 1500 mean?
Downstream O2 sensor circuit volts high.Downstream O2 sensor circuit volts high.
Can a bad gas cap cause code p0138?
Not likely. Code P0138 is------O2 Sensor Circuit High Voltage (Bank 1 Sensor 2).
What typically causes high CO readings on a 91 Honda prelude SI?
High HC is unburnt fuel. Check the O2 sensors, Plugs, wires,cap ,rotor, timing. If it failed CO & Nox also check the converter. Possible that it may not have been properly warmed up before testing. I would recommend looking at the o2 sensor (you only have one on your car) and the coolant temp sensor.
Would a thermostat cause an o2 sensor to fail?
Not directly.
Will a bad O2 sensor cause a 96 Honda accord to shift poorly?
no. a bad o2 sensor will cause more fuel consumption, check engine light, etc it has nothing to do with shifting
Will bad O2 sensor cause bad gas mileage?
yes
Would a faulty o2 sensor cause a '93 sidekick to stall?
Yes, a faulty O2 sensor might cause a 1993 Sidekick to stall. It would also cause the car to misfire and use far more gasoline that it needs.
Why might an '89 Honda Civic fail an emissions test 3 times because of high readings on idling after changing the O2 sensor and catalytic converter?
Depends on which of the readings failed. Was it CO (carbon monoxide), HC (hydrocarbons), NOx (nitrous of oxides), or a combination of them?
How do you replace the oxygen sensor on a 2006 Jeep Wrangler?
Why are you replacing sensor, you have a new car and there are several other problems that can cause a DTC to be set for an O2 sensor. Fuel pressure high or low, vacuum leak, misfire, etc. What are symptoms?
What is the meaning of emission code po138?
O2 sensor circuit high voltage (bank 1 sensor 2)
