The low idle engine speed is between 600 and 750 RPM. The exhaust gas recirculation (EGR) valve position is greater than 0.08 volt. The mass fuel desired (MFDES) is between 4 and 16 mg/stk, at low idle for a minimum of 30 seconds. No exhaust pressure (EP), barometric pressure (BAP), manifold absolute pressure (MAP), pressure signal, intake air temperature (IAT), IAT2 temperature signal, visctronic drive fan (VDF) fan P0480, or EGR related faults. Fault condition: IAT2 exceeds a calibrated temperature for more than 30 seconds, based on IAT temperature.
