The pedals on your unit is mechanical. Seem like one of your shock is faulty. Should be pretty easy to change out.

follow the steps and fix it. God bless you
The power up test sequence has detected a key in the operated condition. The power up test
sequence is performed every time the unit is turned on (powered up). This test is performed
because a permanently stuck key will inhibit the correct operation of the unit.
Possible Causes
1. A key on the display housing is permanently stuck in the operated condition.
2. One of the upper PCA's keypad interface chips has failed.
3. Liquid (perhaps perspiration) is present on the surface of a touch sensitive display.
Possible Remedies
1. Remove the keypad connector cable from the upper PCA. Restart the power up sequence, if
the ERROR 5 is no longer present, the keypad is the cause. The keypad is typically part of
the display housing. Replace the display housing to correct the problem.
2. Remove the keypad connector cable from the upper PCA. Restart the power up sequence, if
the ERROR 5 is still present, the upper PCA is the cause. Replace the upper PCA to correct

Step 1:

see the comment. and fix it. Run the software calibration.
"SAFETY SHUTDOWN Loss of Speed Signal" or "L5" WITH NO belt movement
The speed sensor is not recognizing any motor movement. This displays the error message to the upper board. Refer to the proper flowchart.

Step 2:

The Steps for Newer Style Console Calibration:

1. Locate the calibration area on the rear or underside of the console (a hole, near the console's center, that goes through to the electronics board. (This hole should not have a screw in it.)
   

2. Insert a pencil (eraser end), into the hole and feel around for the cal button (will click when pressed).
   

3. Press the button 2 times (with the pencil eraser). The first click should show CL11 in the console, the second click should show CL21.
   

4. If the process was done correctly, and CL21 appears in the console, you are in "calibration mode." The next few steps consists of pressing buttons on the console and observing settings. This will not require any other tools.
   

5. Press ENTER. CL22 should display in the TIME window and (??) in the SPEED window.
   

6. Press ENTER. CL23 should display in the TIME window and (??) in the SPEED window.
   

7. Press ENTER. CL24 should display in the TIME window and (??) in the SPEED window.
   

8. Press ENTER. CL25 should display in the TIME window and (??) in the SPEED window.
   

9. Press ENTER. CL26 should display in the TIME window. You should then see the letter "E."
   

10. Press ENTER. You should see "SS" or "55" in the console.
    

11. Push the STOP/START button. For safety, at this point, you should step off, or be off, the treadmill.
    

12. Push the ENTER button. The walking belt should start to move, accelerate to maximum speed, then stop on its own.
    

13. When the belt stops, the incline should self test by raising to its highest incline position, then lowering back down to its lowest position.
    

14. Once the incline test is complete, push the POWER button 2 times. The unit should shut off and the console should go completely blank. If this happens, the treadmill is done calibrating and is ready for use.
    

15. If the letter "F" appears in the SPEED or INCLINE window when the power button is pressed 2 times, the treadmill is indicating a failure somewhere either in the SPEED or INCLINE (depending on the window the "F" appeared in). Troubleshooting the failure would be the next step.

Error 5

Description

The power up test sequence has detected a key in the operated condition. The power up test

sequence is performed every time the unit is turned on (powered up). This test is performed

because a permanently stuck key will inhibit the correct operation of the unit.

Possible Causes

2. One of the upper PCA's keypad interface chips has failed.

3. Liquid (perhaps perspiration) is present on the surface of a touch sensitive display.

If you are getting a speed sensor error it usually means that the sensor has died. Try getting ahold of Nautilus to see if can get a replacement. Funny thing is that Nautilus is headquarted in the town i live in and from what i hear they have great customer service because they have happy employees.
If you have a multimeter or a light tester test the power wires to see if power is going to the sensor. If you have power going in it means that the sensor has died.

The E5 error code indicates the electronics on your treadmill require calibration. Recalibrate the machine per the instructions in your manual to clear this error code.

Here is a GREAT FIXYA Post from 2013 that addresses your error code, "L5"
