At low temperatures, it outperforms other catalyst systems, making it a highly cost-effective retrofit for existing facilities where exhaust temperatures are low. Together, our high-activity catalyst and low-pressure drop result in cost-effective NOx reduction.
The Shell DeNOx System offers outstanding operational performance, including low ammonia slip, low-pressure drop, tolerance against tube rupture and direct water contact. For existing installations, no modifications to either the furnace or the heat recovery section are necessary. For new furnaces, the location of the SCR Catalyst System helps maximise the operational flexibility of the furnace.
U029D - Lost Communication With NOX Sensor 'A'
There is no need to panic, there is a simple explanation. The key is to take a deep breath and consider a few simple solutions.
Alternatively A and or B control emission units are called as bank 1 or bank 2. This is not ideal but has a set of simple fixes which we'll address below. The circuit most likely to be affected by this is known as the Controller Area Network bus communications circuit.
But before we get started on the solutions available to you, let's take a look at what the NOx sensor does.
2017 Peugeot Boxer engine warning lamp on
The diesel NOX sensor has a duel-purpose: it is designed to measure both the nitrogen oxide content chemical name is NO or NO2and the oxygen content chemical name O2 in the exhaust.
The NOx sensor is therefore vital in a good, working engine. It is possible to drive for short distances with a faulty NOx sensor, but it will quickly impact the acceleration, and cause lost mileage. As you did understand this part performs Oxygen lambda probe's work and it does measure NOx content, to make sure engine is running smoothly, fuel efficiency is good and enviromental isn't being affected by nitrogen oxides coming out of the exhaust system.
So where is the NOx sensor? We find it located a little up from the SCR catalyst, in a position prime for directly measuring the level of NOx gas sent out by the engine. This is partnered by a NOx sensor located just a little down from the SCR catalyst, in the perfect place to measure the performance of the catalyst itself.
The NOx sensor A is generally screwed into the exhaust pipe, just behind the catalytic converter. This is a pretty severe problem, so it is advisable to deal with it quickly. But what are the symptoms of UD and UE error codes?
Additionally when sensor has malfcuntion car's engine won't work as good as before and fuel consumption will increase as well. The first things to check are the fuses and wiring. Take a look for any obvious loose wires or blown fuses for an easy fix. If everything seems fully functioning, but the NOx sensor error code remains lit up, then replace the NOx control unit sensor, before replacing inspect connectors and plugs as it is very common that these places were affected by water or moisture so before replacing sensor dry them properly.
This will help you to determine whether it is a problem with the sensor itself, or the system which feeds the sensor. If, once you have replaced the sensor, the new NOx sensor does not light up an error code, then you know that the issue was with the NOx sensor itself, and has been fixed.Forums Website Help Members.
Thread starter Bertie Bus Start date Mar 18, Bertie Bus. Hi Just been away for a couple of days in our new van and had the engine warning lamp come on saying check engine. We managed to get it into a Peugeot dealer where we were staying in Herefordshire and the kindly put the diagnostic gizmo on and found three faults all related to the Adblue system. The codes are P, Pe and P20ee. The fitter managed to clear them but soon after we left, they came back on again.
Following there advice as there was no loss of power, we managed to get it back to storage without any problems.

I can't see how we can get these issues in a new van with only miles done! Oh well back to the dealer. Luckily it is still under warranty. Blue Knight Funster. The P fault is telling you that there is some type of problem with the ad-blu injector circuit, or with the injector itself, that delivers your ad-blue to your exhaust emissions gasses. If the system is wonky then it is likely to imbalance the exhaust gas emissions which could potentially lead to your van failing the emissions standards for your particular engine spec.
Hi Blue Knight I wondered if it is a loose connection or something as it is a brand new van! I think but don't quote me the Pe fault code means that the reductant injector is fully closed which could mean along with P that there is a fault with your ad-blu injector circuit.

Anyone experienced or seen this? Was it related to cold spell? Next course of action? Last edited: 31 Dec I imagine being a fairly new car that taking it to Peugeot may help it get fixed under warranty? It will be sorted under warranty I'm sure but I'd hazard a guess that the post catalytic convertor sensor has packed up and the car thinks it is chucking out polar ice cap melting emissions.
One of my Xsara VTS's did this, then after about a week it went off again and never came on again. French crap! If not, i'd take it on a nice long run, give it a good boot on a dual carriageway to get the revs up and burn anything that may be lingering in the exhaust system by getting the temperatures up. If that doesnt work, or you have been taking it on long runs, book it into peugeot.
It will be under warranty and should be fixed F. Give it an italian tune up. Cleaned it and fault didnt come back for almost a year, previously it would come and go at random. But as the others have said get it to Peugeot for them to tell you they can't find a fault.
As suggested, try taking it for a good drive - get the engine nice and hot. If it fails, take it back to the dealer and leave it to them.
Have you actually driven it anywhere, or just let it idle on the drive for half an hour? Yes I had read similar that a good drive might shift the issue but not actually clear the sensor light and then disconnecting and reconnecting the battery would do this.
Don't partilcuarly want to do it, as it isn't my vehicle, I'll try to find out where he bought it and give them a call to get it to them to have a look at things.2020 2021 rasi phalalu
Seems common enough that the anti-pollution sensor on certain peugeots seems fickle. I'll take it out for a good run and see if that autoclears it. Thanks for all the input guys.The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
Evaporative emissions systems test for a leak in the fuel tank and associated hoses. To perform the test, the computer pulls a vacuum and checks to see if the vacuum holds. Each car maker uses a different techniques to check, but most often it's some type of fuel tank pressure sensor. If the change in pressure is outside of the calibration the DTC will set.

The auto repair labor rates vary widely across the country, and even within the same city. How much do you know about cars?
Take the AutoCodes. The first sensor is located at the outlet of the turbocharger and monitors the engine out NOx level. Each NOx sensor contains a sensing cell, a pumping cell, and a heater. A sample of exhaust gas passes through a diffusion gap between the sensing cell and the pumping cell. The NOx sensor maintains a constant reference voltage across the sensing cell. An electronic circuit within sensor controls the pump current through the pumping cell in order to maintain a constant voltage in the sensing cell.
The amount of current required to maintain the reference voltage in the sensing cell is proportional to the concentration of NOx in the exhaust. The smart NOx sensors consist of two components, the NOx module and the NOx sensor element that are serviced as a unit. A circuit or performance condition with a NOx sensor is detected by the NOx sensor module.

A NOx sensor is a requirement under European Union emissions laws, and ensures that your engine is running cleanly and efficiently. All cars that are Euro 5 or Eur o 6 compliant have to have a working NOx sensor.
Mercedes-Benz cars usually have two sensors per car - one downstream and other upstream sensor, on some schemes it shows up as before catalyc converter and after. There is 2 NOX sensors fitted on the exhaust system bank 1 and bank 2, they are also called as upstream and downstream sensors on the star xentry software system.
PF PF63 and Pe error code stands for NOx sensor's short or open circuit or range performance issue at bank 2. But all newer models with EURO6 certificate have two control unit sensors fitted per car - one before diesel particulate filter DPF also known as catalytic converter to measure out NOx content going to it and other sensor after catalytic converter measuring amount of nitrogen oxides leaving exhaust system.
The PF62, PFE1, PF63, P and PE P NOx sensor error codes will pinpoint the problem, but you may have already noticed your check engine light coming on, black smoke being emitted from your exhaust or that your car is not as economical on fuel. A broken or shorted wire, or an unwanted build-up of soot and debris, may cause this. The different error codes refer to the two banks of your exhaust system: P will show if there is a problem with the first bank, while the other two will highlight a problem with the second bank.
For VW cars sometimes it shows warning message with text "check adblue - no engine start in miles", even though adblue tank is full or not empty as it says on the display. You may find that the reductant tank simply needs to be washed through and refilled, however you may also need to replace a sensor also known as probe lambda sonde or the entire module. This latter option is necessary if other testing has failed to rectify the issue.
For GM, Chevy Vauxhall and Opel cars there are little bit different kind of CEL fault codes, but still means the same as other ones mentioned above in our blog. Based on your mercedes benz error code we can offer repair kit, it all depends which error code is being stored in the system, it could be found using OBDII scanner or any other diagnostic tool, there is no need to use dealer software.
Once you have found fault code email our friendly customer services with car model, year, error code and old part number or picture asking for nitrogen oxide sensor repair kit, when we'll receive this information from we'll offer the cheapest option to fix adblue system's malfunction. Usually the cost depends how much you spend on the required parts. To replace part you can do it yourself or pay extra for labour, but it will add-up in the total amount of the expensives.
The most common amount our customers spend to fix this malfunction is about GBP as they prefer to buy probe with control unit. Error cleaning may be required, but just once after replacing upstream front NOX sensor on the exhaust system. A nitrogen oxide sensor in short NOx is high temperature part is used in cars to detect and measure out amount of this compound nitrogen oxides coming out of exhaust system to ensure it meets enviromental laws.Unsolved murders in terre haute indiana
Replacement sensor probe with ballast unit will save you a fortune, solve your NOX problems and you will comply with enviromental emissions laws again. Sometimes when AdBlue system has malfunction it pops out the following warning messages on the dashboard, message may vary depending on the manufacturer of the car mercedes-benz audi vw seat skoda:. As you can see from many above diagnostics trouble codes in short DTC faulty NOx sensor has many different variations of fault codes and car creates fault message based on the problem for example maybe there are too much Nitrogen Oxide, too less, too bad signal etc and it creates special combination of numbers and letters, but the most important thing in diagnosing faulty NOx control emission unit to read whole message and make sure it says NOx sensor and not heater or other part related to emission control system.
Below you will find error codes when sensor ballast also known as control unit fails, when it means you must replace whole unit including probe in other cases probe replacement will do a job.
Lorries and trucks check engine light gives different kind of fault codes, but the defination and meaning remains the same.
