VOLVOUU All Engines (2013 Emissions) Fault Code: P007186 PID: EMS Ambient Air Temperature Sensor Range/Performance

VOLVOUU All Engines (2013 Emissions) Fault Code: P007186 PID: EMS Ambient Air Temperature Sensor Range/Performance

The ambient air temperature signal is sent to the instrument cluster module. The instrument cluster module then transmits the ambient air temperature data to the Engine Control Module (ECM) via the J1939 data lines.

Conditions for diagnostic trouble code (DTC):
1) No ambient air temperature sensor signal

Probable cause
1) Ambient air temperature sensor
2) Wiring harness
3) Ambient temperature below -30??C (-22??F)
