NOx Sensor Repairs in Dundalk – Expert Diagnostics at McKeown Auto Services

At McKeown Auto Services, we offer NOx sensor diagnostics and repairs for diesel and petrol vehicles across Dundalk. The NOx sensor (Nitrogen Oxide sensor) plays a crucial role in reducing vehicle emissions and ensuring that your engine runs efficiently. When it fails, you may experience poor fuel economy, reduced power due to emissions issues.

What Does a NOx Sensor Do?

NOx sensors are fitted to vehicles with selective catalytic reduction (SCR) systems and are designed to monitor nitrogen oxide levels in the exhaust gases. The data is used to control emissions, especially in diesel engines. A faulty NOx sensor can lead to a check engine light, limp mode, or increased AdBlue consumption.

Common Signs of NOx Sensor Failure

• Dashboard warning lights (engine or emissions)
• Loss of engine power or limp mode
• Increased fuel or AdBlue usage
• Failed emissions test
• Poor throttle response

If you’re noticing any of these symptoms, it’s time to book your car into McKeown Auto Services to get your NOx sensor inspected.
