3406E (S/N: 9WR)

Description of Change: The new pressure sensor group has a housing that has a greater resistance to corrosion. This housing improves the durability of the sensor.

Adaptable To: The 169-3725 Pressure Sensor is a direct replacement for the former 161-9930 Pressure Sensor and the 111-2350 Pressure Sensor. The new pressure sensor is adaptable to the engine models that are listed below. Replace the 3 mating connector pins on the engine harness with 9X-3401 Connector Pins, when you install a new pressure sensor.

The serial number effectivity for the new sensor appears in table 1.
