Volvo All Engines (2010 Emissions) Fault Code: SPN 171 FMI 5 PID: Ambient Air Temperature

Category All Engines (2010 Emissions) Tags 171, 2010, 5, Air, All, Ambient, CodeSPN, Emissions, Engines, Fault, FMI, PID, Temperature, Volvo

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.

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