5.6.2.10 Oil Temperature Sensor
Sensor Description:
Threaded 5/8-18 Platinum Resistance Temperature Detector (RTD) probe
General Installation Guidance:
Refer to the applicable engine manual for proper location of the oil temperature sensor. The sensor is
usually installed near the oil filter.
1.
Cut the safety wire and remove the existing vent plug (Figure 5-17), if installed.
2.
To prevent galling of the threads, apply a small amount of engine oil to the probe threads.
3.
Ensure that an unused copper crush gasket is present on the probe, and install the probe into the
engine (black side of crush gasket down).
NOTE
Crush gaskets can only be used once. A new gasket must be installed any time the probe
is removed and installed.
4.
Tighten the probe to the torque as specified by the engine manufacturer.
5.
Safety-wire the probe to the engine case as appropriate.
6.
Connect the supplied connector to the appropriate inputs on the GEA as referenced in the
G900X/G950 interconnects in Appendix F-J. Secure the connector and wire assembly to an
appropriate location in the engine compartment to provide strain relief.

5.6.2.11 Resistive Type Fuel Quantity Senders
Resistive type fuel quantity senders with a 0 – 500
Ω
range are currently supported. This installation
requires inline axial resistors rated to at least 1/4W. Please see the interconnect documentation for proper
wiring considerations.
5.6.2.12 Capacitive Type Fuel Quantity Senders
Only Electronics International P-300C capacitive fuel probes are currently supported. The P-300C
receives a +5V excitation input from the GEA 71 and outputs ±5V square wave from 600 Hz to 3.8 KHz.
Please see the interconnect documentation for proper wiring considerations.
