Description Of Change: New engine oil pressure sensor is now used with EMCP 4.x controls on the above mentioned Engines and Gensets.

Adaptable To: A new active 380-1882 Pressure Sensor Gp is now available for use with EMCP 4.x controls.

The new 380-1882 Pressure Sensor Gp is a direct replacement for the former 265-7429 Pressure Sender. Refer to Table 1.

Perform the following steps for product prior to the effective serial numbers:

Change the harness connector at the sensor to a 297-5484 Connector Plug As with the 5V supply at pin 1, ground at pin 2, and signal at pin 3 using 9X-3402 Connector Socket.
Add an additional 18 gauge wire to the harness from the new active sensor to the EMCP for a 5V supply from Pin 1 of the sensor connector to Pin 16 on the EMCP4.1 and 4.2 models and from Pin 1 of the sensor connector to pin 56, 61, or 62, Analog input 1, 2, or 3 respectively on the EMCP 4.3 and 4.4 models using a 9X-3402 Connector Socket.
Change the analog input 1-3 configurable parameter "Signal Type" in the EMCP from "Passive" to "Voltage".
Change the analog input 1-3 configurable parameter "Signal Range" in the EMCP from "0-5V".
Set the analog input 1-3 configurable parameter "Maximum Data Range" in the EMCP to "600.000".
