Mobile NOx Sensor Repair across South and West Yorkshire

The NOx (nitrogen oxide) sensor monitors exhaust emissions on diesel vehicles fitted with AdBlue systems. When it fails or develops a fault, it can trigger warning lights, cause the AdBlue system to malfunction, and in some cases push the vehicle into a reduced performance or limp mode. On commercial vehicles in particular, a NOx sensor fault can quickly become a significant operational problem.

Diagnosis first

NOx sensor faults are not always what they appear. A warning light pointing to the NOx sensor can sometimes indicate an issue elsewhere in the emissions system, including the SCR catalyst, AdBlue injector, or associated wiring. Newton's Automotive Services uses Bosch diagnostic software to read live NOx sensor data and fault codes accurately, confirming the cause before any parts are ordered or replaced.

What we cover

• NOx sensor fault diagnosis and code reading
• Upstream and downstream NOx sensor replacement
• AdBlue and SCR system fault investigation
• Emissions-related warning light diagnosis
• Post-repair verification and fault code clearing
