Temperature Warning
Conditions Which Generate This Code:
The engine has been running for at least 3 minutes.
The intake manifold air temperature has exceeded
thetrippoi
nt for the machine’s application and the
delay time of 4 seconds has expired. No other
codes for the intake manifold air temperature are
active. Th
e ECM will reset when the intake manifold
air temperature cools below the trip point for the
machine application.
The ECM detects the following conditions:
•
The intake manifold air temperature is greater than
76 °C (168 °F) fo
r the 1106 engine.
•
The intake manifold air temperature is greater than
135 °C (275 °F)
for the 1104 turbocharged engine.
•
The intake manifold air temperature is greater
than 82 °C (179
°F) for the aftercooled 1104
turbocharged engine.
•
Theintakeman
ifold air temperature is greater than
112 °C (233 °F) for the 1104 naturally aspirated
engine.
The ECM will reset when the following conditions
are met:
•
The intake manifold air temperature is less than
74 °C (165 °F) for the 1106 engine.
•
The intake manifold air temperature is less than
133 °C (271 °F) for the 1104 turbocharged engine.
•
The intake manifold air temperature is less
than 80 °C (176 °F) for the aftercooled 1104
turbocharg
ed engine.
•
The intake manifold air temperature is less than
110°C(230°
F) for the 1104 naturally aspirated
engine.
System Resp
onse:
The alarm output is activated. The code is logged.
Possible Pe rformance Effect:
The ECM wil
l derate the engine. The ECM will
continue to derate the engine at a higher rate as the
intake manifold air temperature rises.
Troubleshooting:
Refer to Tr
oubleshooting, “Intake Manifold Air
Temperature Is Too High”.
Results:
•
OK – STOP.
