PACCAR MX (2004 Emissions) Fault Code: P0110 Inlet Air Temperature in Inlet Manifold – Data Erratic, Intermittent or Incorrect, at Ignition On SET CONDITIONS:The PCI ECU (D420) detects that measured boost temperature differs more than 3°C [37°F] from the average of other temperature sensors on the engine for more than 5 seconds (after the ignition has been switched off for at least 8 hours). DIAGNOSTIC CONDITION:This diagnostic runs:1. When the ignition has been keyed off continuously for at least 8 hours2. Difference between the coolant temperature and ambient temperature is less than 15°C [59°F]3. Ambient temperature is more than -20°C...

PACCAR MX (2004 Emissions) Fault Code: P0112 Inlet Air Temperature in Inlet Manifold – Voltage Too Low or Short Circuit to Ground on ECU (D420) Pin (A43) SET CONDITIONS:This DTC is set when the ECU detects a lower voltage than expected on the signal or control circuit of the ECU. DIAGNOSTIC CONDITION:The diagnostic runs continuously when the ignition is keyed on. CORRESPONDING OBD READINESS MONITOR:None RESET CONDITION:The DTC changes to inactive after the diagnostic runs and passes. REPAIR VERIFICATION:1. Clear all DTCs.2. Test drive or operate the vehicle to meet the diagnostic conditions and set conditions.3. Did the DTC come...
