What is normal NOx sensor readings?
What is normal NOx sensor readings?
When the injector is activated outlet nox should drop at least 70%. Normally under steady cruise the nox sensor on a duramax or ISB cummins is around 200-300 ppm.
What does a NOx sensor measure?
NOx sensors monitor the level of nitrogen oxide being emitted by a diesel vehicle to ensure compliance with emissions regulations. Most engines feature two NOx sensors: an upstream and downstream sensor.
How does a NOx sensor work?
Many NOx sensors work by first removing oxygen and then breaking down the nitrogen oxides to provide a reading. Urea, composed of ammonia, is injected into exhaust gas to interact with NOx, converting it into harmless nitrogen and oxygen.
Why are NOx sensors so expensive?
Complexity and Cost Another drawback of amperometric NOx sensors is their high cost due to the multiple chamber design and the requirement for complex electronics to detect nanoampere current levels.
Where are the NOx sensors on a diesel engine?
The assembly uses two NOx sensors: the first sensor (referred to as NOx sensor 1) is located near the turbo downpipe and measures engine out NOx. The second sensor (referred to as NOx sensor 2) measures NOx levels exiting the SCR catalyst.
Where is the NoX sensor on a SCR?
The assembly uses two NOx sensors: the first sensor (referred to as NOx sensor 1) is located near the turbo downpipe and measures engine out NOx. The second sensor (referred to as NOx sensor 2) measures NOx levels exiting the SCR catalyst. The SCR assembly contains a catalyst brick that requires DEF, or diesel exhaust fluid, for activation.
What should the resistance be for a NoX sensor?
Proper value (on 200 Ohm range) – over limit; Connect NOx sensor. Measure (wireset) resistance between Pin [3] and Pin [4]. Resistance should be 55 .. 65 Ohms if OEM NOx sensor connected.* If test [2] shows zero resistance – there is a short circuit in wireset (high probability) or MSD80 CAN driver is damaged (low probability).
Which is the most common NOx measurement technology?
The most common in-situ NOx measurement technology relies on yttrium-stabilized ZrO 2 (YSZ) electrochemical sensors [984], similar in construction and operating principle to broadband oxygen sensors.
The assembly uses two NOx sensors: the first sensor (referred to as NOx sensor 1) is located near the turbo downpipe and measures engine out NOx. The second sensor (referred to as NOx sensor 2) measures NOx levels exiting the SCR catalyst.
How many NOx sensors does a Euro 5 truck have?
Euro 5 trucks usually have 1 NOx sensor. In some cases (such as DAF trucks or in all Euro 6 trucks, such as Volvo, Mercedes, Scania, IVECO, Renault, MAN) there would be 2 NOx sensors (one additional sensor before the SCR system) which would determine the amount of AdBlue needed to inject to have near-perfect NOx conversion.

The second sensor (referred to as NOx sensor 2) measures NOx levels exiting the SCR catalyst. The SCR assembly contains a catalyst brick that requires DEF, or diesel exhaust fluid, for activation.
