Volvo All Engines (2013 Emissions) Fault Code: P22A100 PID: EMS NOx Sensor Circuit High Bank 1 Sensor 2

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) Voltage above normal or shorted high
2) Ignition key in drive position

Probable cause
1) Wires between NOx module and NOx sensor
2) NOx sensor

Detailed information
1) Faulty sensor
