PACCAR MX (2004 Emissions) Fault Code: P0095 Intercooler Temperature – Data Erratic, Intermittent or Incorrect
SET CONDITIONS:
The PCI ECU (D420) detects that the measured intercooler temperature sensor differs more than 3°C [5.4°F] from the average of other temperature sensor readings on the engine for more than 5 seconds (after the ignition has been keyed off for at least 8 hours).
DIAGNOSTIC CONDITION:
This diagnostic runs:
1. When the ignition has been keyed off continuously for at least 8 hours

3. Ambient temperature is more than -20°C [-4°F]
CORRESPONDING OBD READINESS MONITOR:
None
RESET CONDITION:
This DTC changes to inactive when the fault is no longer detected.

2. Test drive or operate the vehicle to meet the diagnostic conditions and set conditions.
3. Did the DTC come back? (Can be pending, inactive or active)
– No, repair successful
– Yes, repair unsuccessful
POSSIBLE CAUSES:
