The BMW's NOx sensors operating conditions enable the sensor to measure the nitrogen levels your BMW vehicle normally emits. NOx sensors are responsible for reducing NOx (Diesel Nitrogen Oxide) after-treatment systems, which protect the environment in BMW vehicles with a urea.

The aft sensor is responsible for determining system performance (although in any efficiency calculation the forward sensor would also be required). I had been monitoring 2 PID's with my Carly app. NOx concentration sensor 1 and 2 on my commute to work and noted the Check Engine light was set.

BMW P2201 fault code: NOx Sensor Circuit Range/Performance Bank 1. Replace faulty NOx sensor for repair. Steps to fix are listed inside.

My GF has a 1 series E87 2010 and when it gets warm the engine warning light comes on. We have checked the codes and it has also been into the garage, looks like the lambda / nox sensor needs replacing and they have quoted £550. The nitrogen oxide (NOx) sensor on the BMW 120i is typically located near the exhaust manifold or along the exhaust pipe before the catalytic converter.

Symptoms of a faulty NOx sensor include check engine lights and poor emission performance. To troubleshoot, inspect wiring and connectors for damage or corrosion.

The Nox Sensor for BMW 1 Series is designed to enhance the overall performance and efficiency of the vehicle by accurately monitoring the levels of nitrogen oxides (NOx) emitted from the exhaust system. Hey there! I had a similar issue with my 2009 BMW 3 Series last year.

The NOx sensor problem is pretty common with these models. In my case, it turned out to be more than just the sensor, there was a damaged wiring harness that connected to the NOx system, and the catalyst itself was partially clogged. The repair involved replacing both NOx sensors (pre and post catalyst), fixing the wiring.
