1. Disconnect the Red and Black leads from the Connector
(Item 30), located on the Solenoid Valve, from Terminals 5
and 6 of the Connector (Item 33) by pushing a screwdriver
into the slot on the top of the Connector; then, pull the two
leads from the Solenoid Valve out of the Connector (See
Figure 10).
2. Remove the four Socket Head Cap Screws (Item 12) and
separate the two halves of the FMCE (See Figure 10).
3. Disconnect the Brown and Blue leads from each of the
Sensors (Item 31) from Terminals 1, 2, 3, and 4 of the
Connector (Item 33) by pushing a screwdriver into the slot

the Sensors out of the Connector.
4. Remove the two old Input and Output Sensors (Item 31)
from the Housing (Item 1) (See Figure 10).
5. Install the first new Input Sensor (Item 31) into the Housing
(Item 1) directly over a high spot on the Drive Disc (Item 4)
(See Figure 11).
6. Adjust the first new Input Sensor probe until it is
approximately 0.03149 In. [0.8 mm] from the high spot on
the Drive Disc (Item 4) and lock the new Input Sensor in
place (See Figure 11).
7. Install the new Output Sensor (Item 31) into the Housing
(Item 1) until it is exactly flush with the probe of the installed
Input Sensor and lock the Output Sensor in place (See
Figure 11).
