Pressure Switches 1 (G193) And 2 (G194)
Some 09G/09M transaxles are equipped with two
pressure switches that screw into the valve body
casting in the locations shown in Figure 7. Both
switches are "normally open" switches that connect to
ground when pressure exceeds approx. 44 psi and are
used to verify valve movement in the valve body
assembly.
Pressure Switch 1 (G193) is used to verify activation
of the K-1 clutch.
Pressure Switch 2 (G194) is used to verify activation
of the B-2 clutch. Therefore, pressure switch 2 is
closed in tiptronic mode only, 1st gear. The only other
time the B-2 clutch is required is in reverse (R) gear.
Pressure Switch 2 does not close in the reverse
position, as reverse is engaged by the manual valve
hydraulically.
Note: Both pressure switches were eliminated in all
09G transaxles from June 2004 on.
