The NOx sensor in a Mercedes Sprinter is an emissions control component that is responsible for measuring the levels of nitrogen oxide (NOx) in the exhaust system. This information is sent to the vehicle’s engine control module, which then adjusts the engine’s air-fuel ratio to maintain optimal emissions levels.

If you suspect that the NOx sensor in your Mercedes Sprinter is faulty and needs to be replaced, it is recommended that you bring your vehicle to an authorized Mercedes service center or a trusted mechanic with experience in working on Sprinters. They can diagnose the issue and recommend the best course of action to restore your vehicle’s emissions control system to proper functioning.

NOx Sensor Mercedes Sprinter 2017

In a 2017 Mercedes Sprinter, the location of the NOx sensor will depend on the engine type.

If your Sprinter is equipped with the 2.1L diesel engine, the NOx sensor is typically located in the exhaust system, just before the SCR (Selective Catalytic Reduction) catalyst.

If your Sprinter is equipped with the 3.0L V6 diesel engine, the NOx sensor is located in the exhaust system, just downstream from the diesel particulate filter (DPF).

It is always recommended to check your Sprinter’s owner’s manual or service documentation for specific information on the location of the NOx sensor in your particular model and year.

NOx sensor fault in Mercedes Sprinter

If you are experiencing a NOx sensor fault in your Mercedes Sprinter, it is likely related to emissions control system issues. A faulty NOx sensor can lead to decreased fuel efficiency, increased emissions, and potentially cause damage to the engine.

Some common symptoms of a NOx sensor fault include:

  • 1. The Check Engine Light is on.
  • 2. Poor acceleration or power.
  • 3. Decreased fuel efficiency.
  • 4. Exhaust smells stronger or different than usual.
  • 5. Rough idling or stalling.

If you suspect a NOx sensor fault, it must be diagnosed and repaired as soon as possible. A diagnostic tool can be used to read the codes stored in the vehicle’s computer and determine the specific issue. In most cases, the NOx sensor will need to be replaced or recalibrated.

The OE number for the NOx sensor used in a Mercedes Sprinter can vary depending on the engine type and model year. Here are a few common OE numbers:

  • – A0009053503
  • – A0009057000
  • – A0009057100
  • – A0009050308

The Continental number for the Sprinter NOx sensor is also dependent on the engine type and model year. Here are a few examples:

  • – 5WK9 6678C (2.1L diesel engines)
  • – 5WK9 6595C (3.0L V6 diesel engines)
