How do we replace the speed sensor cables. Where do we start to replace the original cables?

LS Computer doesn't read the single 8 seconds from the speed sensor The gap between speed sensor & magnet is too far. Adjust it to be within 5mm.

Clean and vacuum inside unit and around senor, check connector is solid and no fray or rubbing on wires.

If the sensor is damaged and caused short circuit. Replace a new speed sensor cable.

Precor Error Code 22 Error Code: 22 Manufacturer: Precor
Model: All Models
Error Description: Error 22, No Motor Pulses at Start Up - Error indicates that the display has sent a command for the drive motor to start, however, the speed sensor has not returned the signal acknowledging that the drive motor has started. Possible Reason:

1. The line of sight between the speed sensor and the speed sensor target is obstructed.
2. Badly worn drive motor brushes.
3. Incorrect gap between the speed sensor and the speed sensor target.
4. Incorrect adjustment of the speed sensor potentiometer (when equipped).
5. Inoperative speed sensor.
6. Faulty lower PCA.
7. Faulty interconnect cable between upper and lower PCA.
8. Faulty upper PCA.

Recommended Action:

1. Using a static safe vacuum cleaner, carefully vacuum out the drive motor compartment. Be sure to thoroughly clean the area between the speed sensor and the speed sensor target.
2. Bady worn drive motor brushes cannot make proper contact with the motor commutator, therefore the drive motor will not start when voltage is applied. Inspect and replace drive motor brushes if necessary.
3. Inspect the gap of the speed sensor to the speed sensor target. Proper gap is 3/16" and the speed sensor photo eye should be aimed at the larger portion of the targets wedge shaped section. If unit has a magnetic speed sensor, the gap between the end of the sensor and the flywheel tooth needs to be 3/16".
4. Locate the speed sensor potentiometer (when equipped) on the lower PCA. Set the speed sensor potentiometer to mid-range. Start the treadmill and increase speed to 6 mph. Carefully adjust the speed sensor potentiometer until the treadmill is operating the smoothest. Increase the speed to full speed and again adjust the speed sensor potentiometer until the treadmill is operating the smoothest. These two adjustments are typically small and are generally only a matter of fine tuning.
5. An inoperative speed sensor will allow the drive motor to start and run briefly before the error appears. If able to access the speed sensor wiring, measure the DC voltage between the speed sensor leads. Two of the leads will always read about 5 VDC. Two will toggle between 0 and 5 VDC as you slowly turn the speed sensor target. If both measurements are not seen, the speed sensor needs replaced. Some units have the speed sensor mounted on the lower PCA and the lower PCA needs replaced.
6. Determine if the lower PCA is bad by swapping with a known good lower PCA.
7. Determine if the interconnect cable is bad by swapping with a know good cable.
8. Determine if the upper PCA is bad by swapping with a know good upper PCA.

The manual for this Elliptical doesn't show any lubrication needed.


Is the unit starting to make abnormal noises like squeaks, thumps, or extra/less resistance?


This is from the owners manual for the Spirit XE295.



Maintenance:
1. Wipe down all areas in the sweat path with a damp cloth after each workout.
2. If a squeak, thump, clicking or rough feeling develops the main cause is most likely one of two
reasons:
i. The hardware was not sufficiently tightened during assembly. All bolts that were
installed during assembly need to be tightened as much as possible. It may be
necessary to use a larger wrench than the one provided if you cannot tighten the
bolts sufficiently. I cannot stress this point enough; 90% of calls to the service
department for noise issues can be traced to loose hardware or the rear rails being
dirty.
ii. Dirt build-up on the rear rails and polyurethane wheels are also a source of noise.
Noise from build-up on the rails can cause a thumping sound that you would swear
is coming from inside the main body of the machine because noise travels, and is
amplified, in the tubing of the frame. Clean the rails and wheels with a lint free cloth
and rubbing alcohol. Stubborn build-up can be removed with your thumbnail or a
non-metallic scraper, like the back edge of a plastic knife. After cleaning, apply a
small amount of lubricant on the rails with your fingers or a lint free cloth. You only
need a thin coat of lubrication, wipe off any excess.
3. If squeaks or other noises persist, check that the unit is properly leveled. There are 4 leveling
pads on the bottom of the rear rails, use a 14mm wrench (or adjustable wrench) to adjust the
levelers.

The most common cause for the Timer to Stop After 7 Seconds on a Precor Elliptical is NO RPM Feedback.
Knowing the status of the unit from its last use as well as the last service or part replacement is a great place to start.
Check the connection of the speed sensor to the lower board. Reset connection if necessary.
Check the magnet. The magnet is located on the user's right crank arm on versions 1 and 2 and the user's left on version 3. The magnet passes the speed sensor with each revolution of the crank arm. The magnet should be installed so that its south pole is facing the speed sensor. You can check the magnet polarity with another magnet that has marked poles or a compass. The north pole of the marked magnet or the south facing needle should be attracted to the magnet. Correct magnet installtion if necessary.
You may also check the spacing of the speed sensor to the magnet. The spacing should be 1/8" to 1/4". Adjust if necessary.

Replaced Crank Arm on Precor EFX 546 and Display Doesn Work

I took a magnet from a magnetix toy and secured it to the correct side of the flywheel. It's working now...I just finshed doing it. Hopefully it'll continue working. Thanks for pointing out the magnet was on the wrong side.

My Precor Elliptical Shuts Down After 7 Seconds what is wrong

I have this same problem and called the customer service. The problem is that the rpm sensor is not working. It could be the sensor or something else. They had me check the connections first for the wiring harness at the top and middle and then sent me parts to work on the inside where I have my problem. I am still working on mine because the magnet was installed on the wrong side of the flywheel. Hope you don't have this issue.
