NOx Sensor Replacement – Ballybofey

At Cartech Automotive, we offer fast and accurate NOx sensor replacements in Ballybofey for all makes and models.

If your vehicle is showing emissions-related warning lights or running in limp mode, a faulty NOx (Nitrogen Oxide) sensor could be to blame. Our technicians use advanced diagnostic tools to quickly identify sensor faults and carry out professional replacements to restore performance and compliance.

Why Is the NOx Sensor Important?

The NOx sensor is a key component in your vehicle’s emissions control system, especially in diesel engines fitted with Selective Catalytic Reduction (SCR) technology. It monitors nitrogen oxide levels and sends data to the ECU to manage AdBlue injection and emissions output.

When a NOx sensor fails, you may notice:

Reduced engine power or limp mode
Emissions warning lights on the dashboard
Increased AdBlue consumption
Failed NCT due to high NOx emissions

Ignoring these signs can lead to engine inefficiency and NCT failure.
