SV-EMS-220/221 Installation and Configuration

Rotax 912, Rotax 914, and Jabiru Oil Pressure
If you are installing on a Rotax or Jabiru engine, your engine comes with a pre-installed oil
pressure sensor.
Prior to mid-2008, Rotax provided an oil pressure sensor with 2 tabs for electrical connection. If
you are using this sensor, connect one of the tabs to a general purpose input pin and connect
the other tab to ground (an SV-EMS-220/221 ground is appropriate.
In mid-2008, Rotax switched to a new type of oil pressure sensor made by Honeywell (Rotax
P/N 956413) with an integrated cable. Connect the red wire of the newer sensor to SV-EMS-
220/221 D37 pin 15 (+12 volt Auxiliary), the white wire to SV-EMS-220/221 D37 pin 6, and the
black wire (if present) to ground - ) – See Table 38. Select the correct sensor type as described
in the EMS Sensor Definitions, Mapping, and Settings Section.
Rotax Sensor Connector Pin Rotax Connector Wire Color SV-EMS-220 Connection
N/A White Pin 6 (White/Yellow wire)
N/A Red Pin 15 (Red wire, can be
shared)
N/A Black (if present) Pins 3, 13, 16, 17, or 30 (Black
wire, can be shared)

In late 2012, Rotax further switched to a new oil pressure sensor (Rotax P/N 456180). It is
functionally identical to the previous Honeywell (Rotax P/N 956413) sensor, and connects in the
same fashion as it. However, the connector and wiring for the sensor that Rotax includes with
the engine may require some assembly. See the diagram below for the pinout of the connector.
Connect the wire connected to sensor pin B of the sensor to SV-EMS-220/221 D37 pin 15 (+12
volt Auxiliary), the wire connected to sensor pin C to SV-EMS-220/221 D37 pin 6. Sensor pin A
need not be connected at all. Select the correct sensor type as described in the EMS Sensor
Definitions, Mapping, and Settings Section.
