(8) Overspeed Sensor
(9) Turbo Inlet High-Temperature Shutdown Sensor (Bank B)
(10) Oil Pressure Switch
# Coolant Temperature Switch #
Monitors engine coolant temperature
The provided switch is used to connect to the panel supplied by the OEM.
# Boost Pressure Sensor #
Measures pressure in the intake manifold
Signal is sent to ECU (1)
# Oil Pressure Sensor #
Installed on both sides of the engine;
The engine oil pressure sensor is installed in the main oil gallery;
The provided engine oil pressure sensor is used to connect to the panel supplied by the OEM.
# Turbo Inlet High-Temperature Shutdown Sensor #
# Thermocouple #
Four thermocouples are installed.
Each thermocouple is installed on each pipe of the exhaust manifold.
There are two turbo inlet high-temperature shutdown sensors.
One sensor monitors each bank of engine cylinders.
One sensor monitors two thermocouples.
If a high temperature is indicated, the engine will shut down.
# Speed Sensor #
Speed sensor failure
If the ECU (1) does not receive a signal from the speed sensor (4), the engine will not run.
If the ECU does not receive a signal from the speed sensor (7), the engine will shut down. The faulty speed sensor should be replaced.
Note: Intermittent failure of the speed sensor can cause unstable engine operation. This may also cause overspeed.
# Overspeed Sensor #
The signal from the overspeed sensor is connected to the overspeed switch or the overspeed circuit in the panel provided by the OEM.
