Usage:
3406E (1MM, 1LW, 2WS, 5DS, 5EK, 6TS) Truck Engines
Description of Change: Several improvements have been made to the atmospheric pressure sensor that is used in the above 3406E Truck Engines. These improvements to the atmospheric pressure sensor will help to prevent the entry of moisture into the sensor. This will help to increase the service life of the sensor.
Adaptable To: The improved 111-8125 Atmospheric Pressure Sensor became effective with 3406E (1LW, 5DS, 5EK, 6TS) Truck Engines in May 1998. This sensor may be used on any 3406E (1LW, 5DS, 5EK, 6TS) Truck Engines produced prior to 1999.
The improved 111-8125 Atmospheric Pressure Sensor has been in effect in the parts system since the second quarter of 1998.
All 1999 model year 3406E (1MM, 2WS) Truck Engines use the improved 161-9925 Atmospheric Pressure Sensor. This pressure sensor incorporates all of the improvements which have also been made to the 111-8125 Atmospheric Pressure Sensor, but is not interchangeable with the other sensor.
