Volvo All Engines (2017 Emissions) Fault Code: P011001 PID: EMS Intake Air Temperature Sensor 1 Bank 1

Volvo All Engines (2017 Emissions) Fault Code: P011001 PID: EMS Intake Air Temperature Sensor 1 Bank 1

The Boost Air Temperature Sensor is used to monitor the temperature of the air in the intake system after the turbocharger. The sensor is a Negative Temperature Co-efficient (NTC) type temperature sensor.
The sensor signals are used to calculation fuel injection and is monitored by the Engine Control Module (ECM).
The engine control module (ECM) will set a diagnostic trouble code (DTC) and derate the engine to avoid engine damage if the sensor signal is not within predetermined limits, or the signal is not rational.

Conditions for diagnostic trouble code (DTC):
1) General Electrical Failure

Probable cause
1) Intake manifold air temperature (IMAT) and pressure sensor
