No installation is required for the engine oil pressure monitoring function.
14.2.3 Intake Manifold Temperature
14.2.3.1 Intake Manifold Temperature Monitoring Mode Operation
The engine intake manifold air temperature is monitored by the engine
management system to ensure that the engine remains emissions compliant
when high intake manifold temperatures are measured. The values shown
below are factory set values, where the max temperature is set to 129°C.
This value is non-configurable.

Table 14.8 Intake Manifold Temperature Monitoring Mode Derate Operation
Once the engine ECM detects that the engine intake manifold air temperature
has exceeded one or more of the defined threshold limits a corresponding
event code is raised as shown below.

14.2.3.2 Intake Manifold Temperature Monitoring Mode Configuration
Using the Perkins EST service tool the following parameters can be
configured.
The Maximum Intake manifold temperature limit is set within the ECM
software and cannot be adjusted however the trigger points for severity L1
and severity L2 functions can be configured below this value within the
following range shown below.
