Among all other errors, U059E and U059F are the error codes which mean that the data communicated by NOx sensor A and NOx sensor B of the car is not valid.
What is code U059E?
Description : U059E Invalid Data Received From NOX Sensor ‘A’ Possible causes : – Faulty Nitrogen Oxide (NOx) Sensor. – Nitrogen Oxide (NOx) Sensor harness is open or shorted. – Nitrogen Oxide (NOx) Sensor circuit poor electrical connection.
What is a downstream NOx sensor?
The NOx sensor downstream of the SCR catalyst is used to monitor the performance of the catalyst. Accurate NOx measurement is in high demand to comply with increasingly strict NOx emissions regulations. The NOx sensor is also capable of measuring O2 concentration, just like a wide range air-fuel sensor.
What does code P229F mean?
What does the Mercedes Benz P2202 P229e P229F error codes mean? This is a generic code to signify the electronic control module of your vehicle has detected that the sensor signal of your NOx sensor is low on bank one. It is caused by the ECM receiving lower than expected voltage from the signal wire.
Is it safe to drive with a faulty NOx sensor?
In short, the answer is yes, you can drive a car that has a faulty knock sensor. That being said, you may not want to. The prolonged driving of a car that has a bad knock sensor can cause a lot of damage to the engine.
What causes a NOx sensor to go bad?
Most engines feature two NOx sensors: an upstream and downstream sensor. Common causes of failure include soot buildup on the sensor, ECU water intrusion, and/or damage to the cable, which will cause the check engine light to illuminate.
How much does it cost to replace a NOx sensor?
U029D normally means Lost Communication With NOX Sensor ‘A’. 2 NOX sensor equipped in Dodge Ram Van. One seated behind turbo, 61955-44600, called as sensor bank A with dealer price US$700-US$900, is responsible for monitoring the engine out NOX level.

How do you reset a NOx sensor?
Go to the System menu, select Engine, then choose the specifics for your vehicle and go to Functional Tests, followed by Special Functions. At the next screen pick Adaptations then scroll down to find Reset Learned Values Of NOx Sensor Upstream And Downstream Of SCR Catalytic Converter.
Can you delete a NOx sensor?
NOx sensor is very expensive to repair or change. With cancellation of NOx sensor system from vehicle you will save costs of repair and fuel consumption. ECU of the vehicle is modified to remove NOx sensor system and NOx sensor itself is removed from vehicle.
