Code
Description Notes
105-3 Engine Intake Manifold #1
Temperature : Voltage
Above Normal The Electronic Control Module (ECM) detects the following conditions:
The signal voltage for the intake manifold temperature sensor is greater than 4.94 VDC for at least 0.5
seconds.
The battery voltage is at least 10 VDC.
The ECM will use a default value for the intake manifold temperature while this diagnostic code is
active.
The engine will be derated.
105-4 Engine Intake Manifold #1
Temperature : Voltage Below
Normal The ECM detects the following conditions:
The signal voltage for the intake manifold temperature sensor is less than 0.26 VDC for at least 0.5
seconds.
The battery voltage is at least 10 VDC.
The ECM will use a default value for the intake manifold temperature while this diagnostic code is
active.
The engine will be derated.
110-3 Engine Coolant Temperature
: Voltage Above Normal The ECM detects that the signal voltage for the coolant temperature sensor is greater than 4.93 VDC
for at least 0.5 seconds.
The ECM will use the default value for the coolant temperature while this diagnostic code is active. The
default value is −10° C (14° F) at engine start, gradually increasing to 90° C (194° F) as the engine is
running.
The engine will be derated.
110-4 Engine Coolant Temperature
: Voltage Below Normal The ECM detects that the signal voltage for the coolant temperature sensor is less than 0.2 VDC for at
least 0.5 seconds.
The ECM will use the default value for the coolant temperature while this diagnostic code is active. The
default value is −10° C (14° F) at engine start, gradually increasing to 90° C (194° F) as the engine is
running.
The engine will be derated.
172-3 Engine Air Inlet Temperature
: Voltage Above Normal The ECM detects that the signal voltage for the air inlet temperature sensor is greater than 4.9 VDC for
at least 0.5 seconds.
While this code is active, the ECM will gradually increase or decrease the air inlet temperature from the
last valid reading until the default value is reached. The default value is 30° C (86° F).
172-4 Engine Air Inlet Temperature
: Voltage Below Normal The ECM detects that the signal voltage for the air inlet temperature sensor is less than 0.2 VDC for at
least 0.5 seconds.
While this code is active, the ECM will gradually increase or decrease the air inlet temperature from the
last valid reading until the default value is reached. The default value is 30° C (86° F).
