Volvo All Engines (2017 Emissions) Fault Code: P229E1C PID: EMS NOx Sensor Bank 1 Sensor 2
Volvo All Engines (2017 Emissions) Fault Code: P229E1C PID: EMS NOx Sensor Bank 1 Sensor 2
Circuit description
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)
Incorrect value, Voltage supply
Probable cause
1) Wiring harness
2) NOx sensor
Detailed information
Faulty sensor
