Volvo All Engines (2013 Emissions) Fault Code: P220A1C PID: EMS NOx Sensor Supply Voltage Circuit (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 value, Voltage supply

Probable cause
1) Battery cable connections
2) Battery
3) Wiring harness
4) Faulty sensor

Volvo All Engines (2013 Emissions) Fault Code: P222601 PID: EMS Barometric Pressure Circuit

The Ambient Pressure Sensor is located inside the Engine Control Module (ECM) and can therefore not be checked.
The signal is used to calculate intake manifold pressure (IMP) as well as to compensate for fuel when driving at high altitudes.
The engine control module (ECM) will set a diagnostic trouble code (DTC) if the sensor signal is not within predetermined limits, or the signal is not rational.

Conditions for diagnostic trouble code (DTC):
1) The barometric pressure (BARO) from the sensor is irrational

Observable symptoms
1) Poor response at high altitudes

Probable cause
1) Barometric Pressure (BARO) Sensor

Detailed information
1) The sensor is located in the engine control module (ECM) and therefore cannot be checked
2) The signal is used to calculate intake manifold pressure (IMP) as well as to control fuel compensation when driving at high altitudes
