Volvo All Engines (2013 Emissions) Fault Code: P22F900 PID: EMS Nox Sensor Performance – Slow Response Low to 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.

Conditions for diagnostic trouble code (DTC):
1) Incorrect response

Probable cause
1) NOx sensor
