2001 tauras will not go into gear it is stuck in park and will not shift. The transmision shifts fine. Thiss problem has been going on for a couple of days but would correct when the cars warms up. Today it will not work at all
Do you
have the same problem?

? Fuse No. 17 (15-amp) or fuse No. 32 (10-amp).
? Ignition/shifter interlock cable.
? Brake Pedal Position (BPP) switch connections.
? Wiring harness.
? Shift interlock actuator.
Diagnostic Procedure

1. Apply the brake pedal and view the brakelights. Do the brakelights illuminate? If so, go to step
7. If not, go to next step.
2. Measure resistance in fuse No. 17 (15-amp). Is the resistance of the fuse 5 ohms or less? If so,
go to step 4. If not, go to next step.
3. Ensure ignition switch is in OFF position. Disconnect Brake Pedal Position (BPP) switch
harness connector. Measure the resistance in Light Green/Red wire between BPP switch
harness connector and ground. Is the resistance less than 10 k/ohms? If so, repair short to
ground in Light Green/Red wire and test the system for normal operation. If not, go to next
step.
4. Measure the resistance in Light Green/Red wire between output side of fuse No. 17 and BPP
switch harness connector. Is the resistance less than 5 ohms? If so, go to next step. If not, repair
open in Light Green/Red wire and test the system for normal operation.
5. Measure the resistance between BPP switch terminals No. 1 and 2 (component side), while
open (OFF) and closed (ON). Is the resistance of the switch greater than 10 k/ohms while OFF,
and 5 ohms or less while ON? If so, go to next step. If not, replace BPP switch and test the
system for normal operation. See BRAKE PEDAL POSITION SWITCH under REMOVAL
& INSTALLATION.
6. Disconnect shift interlock actuator harness connector. Measure the resistance in Red/Light
Green wire between shift interlock actuator harness connector and ground. See Fig. 16. Is the
resistance less than 10 k/ohms? If so, repair short to ground in Red/Light Green wire and test
the system for normal operation. If not, go to next step.
7. Measure the resistance in Red/Light Green wire between shift interlock actuator harness
connector and BPP switch harness connector. Is the resistance less than 5 ohms? If so, go to
next step. If not, repair open in Red/Light Green wire and test the system for normal operation.
8. Measure the voltage in Orange wire between shift interlock actuator harness connector and
ground. See Fig. 18. Does battery voltage exist? If so, go to step 12. If not, go to next step.
9. Turn ignition switch to OFF position. Measure resistance in fuse No. 32 (10-amp). Is the
resistance less than 5 ohms? If so, go to step 11. If not, go to next step.
10. Measure the resistance in Orange wire between shift interlock actuator harness connector
terminal No. 3 and ground. See Fig. 19. Is resistance less than 10 k/ohms? If so, repair short to
ground in Orange wire and test the system for normal operation. If not, go to next step.
11. Measure the resistance in Orange wire between output side of fuse No. 32 (10-amp) and shift
interlock actuator harness connector terminal No. 3. See Fig. 61. Is the resistance less than 5
ohms? If so, go to next step. If not, repair open in Orange wire and test the system for normal
operation.
12. Measure the resistance in Black wire between shift interlock actuator harness connector
terminal No. 2 and ground. See Fig. 12. Is the resistance less than 5 ohms? If so, replace shift
interlock actuator and test the system for normal operation. See SHIFT INTERLOCK
ACTUATOR under REMOVAL & INSTALLATION. If not, repair open in Black wire and
test the system for normal operation.

Check the brake lights if its coming on-if okay have the shift interlock control system checked -could be the shiftlock control solenoid acting up-
