The performance of CO catalytic converters is controlled by one or two wide-band Lambda probes one — for N43 series engines, two — for N53 series engines. More about the control of CO catalytic converters — read here.

If the performance of CO catalytic converter is very, very weak close to no performanceMSD80 records error message also in Stratified charge mode. If the error messages regarding decreased insufficient performance of CO catalytic converter are recorded in Homogeneous mixture mode:.

If the error messages regarding insufficient performance of CO catalytic converters are recorder in Stratified charge mode:.

In case, when Stratified charge is turned off completely, the problems, which are typical in case of damaged NOx system — uneven running of engine, error messages regarding trim, misfire etc.

Note: it is interesting, that the N43 series engine has two different error messages regarding performance of CO catalytic converter for each of banksbut the catalytic converter is only one. If the Stratified charge is completely turned of because of insufficient performance of CO catalytic converter:. Create new long-term trims. If in the process of creating new long-term trims error messages 2A26 and 2A27 are observed — the performance of CO catalytic converters is very low.


Some cases with long-term trim problems are described here and here. In this case: check the coding of injectors the problem described hereeliminate all other error messages and also their causes especially everything that concerns NOx systemfully delete all long-term trims of 2-nd group, very carefully perform new long-term trims how — read here and here. How to do it safely: turn on the Stratified charge.

In case of reduced performance of CO catalytic converter also the desulphuring of NOx catalytic converter can be disturbed, accordingly — after some period of time also error message 30EA will appear, even if you regularly drive with speed above Unfortunately the attempt to modify the exhaust system with the goal the decrease the speed of airflow to control probe, failed.

If the reduction of air inflow was too little, MSD80 detected insufficient performance of CO catalytic converter, if the air inflow was too high — also the signal of control probe is detected are incorrect because idrac9 enterprise growing group delay.

Petrol engines, Exhaust gases and TI. Flow rate data coding of injectors. How I perform N53 adaptations. Skip to content. To approximately evaluate the performance of CO catalytic converter: 1.Oxygen sensors should be replaced everymiles.

In a perfect world that would be it, wait until a specified mileage and replace the sensor. However, these sensors fail prematurely, set oxygen sensor fault codes and reduce fuel economy. In this article, I will show you how to identify the location of all 4 oxygen sensors and how to replace them. You will need an oxygen sensor socket to remove the sensors and remember to always work with a cool exhaust.

Oxygen sensors are fragile, do not drop, damage may occur. Also, keep sensor tip clean when reinstalling. Oxygen sensors are laid out in banks which refer to cylinders and in sensor numbers referring to before or after the catalytic converter. Bank1 or B1 refers to cylinders Bank 2 or B2 refers to cylinders Sensor 1 or S1 refers to sensor before catalytic converter. Sensor 2 or S2 refers to sensor after catalytic converter.

Bank 1 Sensor 1, green arrow. Bank 2 Sensor 1, yellow arrow Bank 2 sensor is hard to see in this photo, yellow arrow points to where it is. It is buried beneath the ignition wiring harness.

Large Image Extra-Large Image. Bank 1 Sensor 2, green arrow. Bank 2 Sensor 2, yellow arrow Replacing sensors before catalytic converter Remove engine covers. See our tech article on engine covers removing. Oxygen sensors are located in exhaust manifold. Locate oxygen sensor electrical connectors at right side of engine above exhaust manifold. Label or mark connectors to aide during reinstallation.

I suggest replacing one sensor at a time so you do not mix up connectors.Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. P BMW Tech Notes As the code description implies the P code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly is not as efficient as the factory is expecting.

Replacing the oxygen O2 sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P code is combined with other codes, try fixing the other codes first. What does this mean? The auto repair labor rates vary widely across the country, and even within the same city. When is the P BMW code detected? A three way catalyst converter Manifold with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2.

As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase. When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst malfunction is diagnosed.

Get Access to Factory Service Manuals. Related Information. Repair Importance Level: 2. Why is the Engine Light ON?Q1: Why my car needs NOx sensor? A1: NOx sensor monitors the NOx amount in exhaust gases. Without these data, engine disables Stratified charge and Homogeneous lean injection modes.

As a result, fuel consumption grows. Also, there are some side effects if NOx sensor is broken or disconnected also, if error messages relating NOx catalytic converter are recorded : engine starts shaking; rough run and misfires appear. Problems with NOx system can be the cause of error messages about fuel trim, Lambda probes, insufficient efficiency of CO converters, misfires. More information read here. If the NOx catalytic converter has aged or is damaged, the NOx sensor determines it — the need to replace the expensive catalytic converter is inevitable.

NOXEM measures all possible parameters in real-time. This manner guarantees the best possible performance over all conditions. A5: Situation is a little bit complicated than it looks at the first moment. If the Stratified charge is selected at idle, the NOx amount is small because the amount of burned fuel also is very small.

The worst region from emission side is driving with speed In this area, NOx content could exceed allowed limits if the remaining efficiency of the NOx converter is low. At the same time — the content of CO and CH is significantly lower compared with the same engine, working on Homogeneous mode if there are problems with NOx system. A6: Yes, you will pass the technical inspection if all systems except NOx catalytic converter are in working condition — NOXEM will not affect it in any negative way.

A7: No, it is not possible to identify it. The engine produces a higher level of NOx only under real load conditions. While the exhaust gases are measured, the vehicle stands still independently of the range of RPMand the level of NOx will be in accordance with admissible standards. Moreover — regular technical inspections do not include measurements of NOx amount in exhaust gases. Both conditions guarantee max low fuel consumption and max long work-life of the exhaust system.

NOXEM allows you to save extra During regeneration, the engine burns the additional amount of fuel to heat the NOx catalytic converter. In the process of desulfation also an additional amount of fuel is burned, to keep the temperature of the exhaust system high. Moreover, when using NOXEM, you can avoid desulfation sessions at all — it allows you to save both, additional fuel and money.

A9: Yes, you will be able to go back to the original setup of the exhaust system. If you will use your right of withdrawal, Bimmerprofs will return the money you spent on NOXEM read more in warranty terms.Im making this post for those n54 guys who dont have enough time to research enough to find a solution for your n54 issues.

Codes that come from non-ECU modules are not listed here and generally not related to modifications, so take your car to the dealer for those. FIX: This code itself is meaningless and serves only to let you know a 'limp mode' took place. FIX: Plug back in and clear code. Code will not appear if you disconnect and plug the vacuum line on the exhaust flapper directly. FIX: Currently no solution other than reinstalling your factory cats. You may also delete codes when they appear and live with the problem.

Ignore it. Common issue. Unplugging map sensor or tune with ECU awake will cause this. As will various other tuning related problems. FIX: Clear code. If it comes back, check tune related wiring and consult with tuner. Often comes up when TMAP is unplugged from charge pipe blowing off. If it comes back, check tune related wiring or TMAP sensor. Just ignore it. FIX: Dealer it. If your tune is equipped with lagfix, the first step is to disable it.

If problem persists email your tuner for support. Also possibly tuning related. FIX: Check wiring. Green and purple wires on JB3. FIX: Excessive knock retard. Lower boost levels, or run higher octane. Originally Posted by Trunksi7 Post Mod list?Remember Me?

I haven't yet pulled the O2 sensors out yet. What available actual values should I be looking for in the BT tool to torubleshoot the problem.

What voltage or other values should i be looking for to see which O2 Sensor it is or even worse which Catalytic converter it is. No Warranty, I bought it on Auction it was hit in the back quarter panel. It's a brand new car. Appreciate 0. Good Luck. Does it say what the threshold values should be? Nope, no values. Are these codes usually because of bad catalytic converters or bad O2 sensors. The car wasn't driven for 6 months before i bought it. Can new catalytic converters go bad so quickly?

Last edited by cezary; at AM. I guess the first thing I should to is get an emissions test done.

I get those codes now after going catless dps. Not sure if that helps. Do you get the Service Engine Soon light?The function of the catalytic converter is to break down harmful pollutants that are created by your vehicle during the combustion cycle and convert them into less harmful gases. Code P indicates that the catalytic converter is not functioning efficiently, therefore increasing the output of harmful pollutants by the vehicle.

While P does not pose a danger to the driver, it can cause driveability concerns such as a lack of power or poor acceleration if left unrepaired.

N43/53 and CO catalytic converters

It can also cause severe damage to other components of your vehicle if not addressed in a timely manner. It is recommended that you address P as soon as possible to keep the cost of the repair to a minimum. Do not overlook other codes that are paired along with P If the catalytic converter is replaced without repairing the misfire, the new catalytic converter will go bad again.

If these codes or any other codes are present, they should be addressed first. For error code P, one or more of the below repairs may be needed to solve the underlying issue. For each possible repair, the estimated cost of repair includes the cost of the relevant parts and the cost of labor required to make the repair.

The consistency of your voltage reading means that your downstream O2 sensor is operating correctly. My Downstream O2 Sensor voltage reading is a consistent.

Any ideas? I just replaced both 02 sensors Bank 1 sensor 2 and bank 2 sensor 2 last week and my check engine light came on today with the code p I tried pushing the Clear Check Light about times and the light stayed on. Turned engine off and back on and the light is still on. I took it to the Dealer about 6 months ago when the light came on.

Then cleared the light until now. If the downstream O2 sensor on Bank 2 is jumping between 0. I just replaced my catalytic converter and all O2 sensors less than 5 months ago and this code was thrown while cruising down the highway. Could this be caused by something I had replaced improperly? I have the same on my 5.
