A NOX sensor is a nitrogen oxide sensor. It is used in a car's exhaust system to check emissions for nitrogen oxide.
It is a sensor that measures/ detects oxides of nitrogen.
A Nox sensor is very similar to a lambda probe, but its dedicated to measuring oxides of nitrogen in the exhaust gas. It looks pretty much the same and goes into the exhaust just like a lambda probe.
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
the oxygen sensor is in the exhaust manifolds, there should be one for each side
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.
If there are no other problems and the vehicle is failing the NOX emissions test, it's probably running too lean. Check the EGR valve, fuel pressure and the Oxygen sensor.
i had the same problem i have replaced the nox wire and nox sensor it took care of that also check the sensor on top of the transmission
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
------------------------------------------------------------ The PCV is right above the pullies on the front of the engine. There is a sensor right above it (MAF sensor?) Get the kit from the dealer: Part #17113515 What is the function of the PVC valve ? Does it control or block out NOx vapors which pass through the exhaust system and affect the tests results of the auto Emissions Inspection program? it's the MAP sensor the pcv's function is to clear crankcase vapors that blow by the piston rings HC not NOx. the EGR recirculates exhaust gases to cool combustion chamber temps and reduce NOx emissions.
There are 2 knock sensor on the 5.3L engine. And they are under the intake manifold. To get to them you will have to remove the whole top of the engine- INTAKE MANIFOLD. Why do you think they need replaced???? check engine light came on for 2 sensor

Bona nox was created in 1788.
