Volvo All Engines (2017 Emissions) Fault Code: P054070 PID: EMS Intake Air Heater “A” Control Circuit descriptionThe preheat function is used to warm up the inlet air during cold conditions both before and after cranking to make the starting easier and better for the environment at very low temperatures. This diagnostic trouble code (DTC) detects a faulty preheat function. Conditions for diagnostic trouble code (DTC)Intake air heater (IAH) relay not activatedThe voltage at pin A14.EB:7 is more than 91 % battery voltage Observable symptomsIntake air heater (IAH) relay may be constantly activatedHigh intake air temperature (IAT)High current consumptionLow battery voltage Probable...
