Intrepid V6-3.5L VIN V (2002)
The switches are continuously monitored by the PCM for the correct states (open or closed) in each gear as shown in the chart.
PRESSURE SWITCH STATES
A Diagnostic Trouble Code (DTC) will set if the PCM senses any switch open or closed at the wrong time in a given gear.
The PCM also tests the 2/4 and OD pressure switches when they are normally off (OD and 2/4 are tested in 1st gear, OD in 2nd gear, and 2/4 in 3rd
gear). The test simply verifies that they are operational, by looking for a closed state when the corresponding element is applied. Immediately after a shift
into 1st, 2nd, or 3rd gear with the engine speed above 1000 rpm, the PCM momentarily turns on element pressure to the 2/4 and/or OD clutch circuits to
identify that the appropriate switch has closed. If it doesn't close, it is tested again. If the switch fails to close the second time, the appropriate Diagnostic
Trouble Code (DTC) will set.
