NOx Sensor Repair – Dublin

NOx Sensor Repairs at D Fitzgerald Autos in Dublin

At D Fitzgerald Autos in Dublin, we’re skilled in diagnosing and repairing faulty NOx sensors to keep your vehicle running efficiently and environmentally friendly.

NOx sensors play a critical role in reducing your vehicle’s emissions and ensuring compliance with environmental regulations. These sensors monitor nitrogen oxide (NOx) levels in the exhaust system, helping your car’s engine management system maintain optimal performance and minimise harmful emissions.

How do I know my NOx sensor is faulty?

Common signs of a faulty NOx sensor include reduced engine performance, increased fuel consumption, and warning lights on your dashboard, particularly the Check Engine or AdBlue light. You might also experience difficulties with the vehicle’s emissions system, such as the failure of the selective catalytic reduction (SCR) system. If left unresolved, a faulty NOx sensor can lead to more severe problems, including damage to the exhaust system or failing an MOT emissions test.
