VOLVOUU All Engines (2013 Emissions) Fault Code: P225C00 PID: EMS NOx Sensor Performance – Signal Stuck High Bank 1 Sensor 1

The NOx sensor measures the amount of NOx in the exhaust system. The NOx sensor is connected in the J2284/ISO data link. This diagnostic trouble code (DTC) indicates a NOx monitoring failure. For example; NOx sensor short- or open circuit, NOx sensor removed, NOx sensor missing signal.

Probable cause
1) Sensor not mounted in exhaust stream
2) NOx sensor

Detailed information
1) Faulty sensor
