SOURCE: What does code 22 mean?
Error 22 - No Motor Pulses at Start Up
Error 22 indicates that the drive motor (running belt) has been instructed to start, by either
manual or program control, and the monitoring system has not received any response from the
speed sensing system indicating that the drive motor has started.
1. The treadmill utilizes an optical (infrared) speed sensor and the line of sight between the
speed sensor and the speed sensor target is obstructed.
2. Drive motor brushes are bad.
3. The speed sensor position relative to the speed sensor target is incorrect.
4. The speed sensor potentiometer adjustment is incorrect (when equipped).
5. The speed sensor is inoperative.
6. The lower PCA is bad.
7. The lower PCA to upper PCA interconnect cable is bad.
8. The upper PCA is bad

Hello I hope everything is fine.
I will give some Tips:
Description Errors 00 through Error 04 check upper PCA memory locations, RAM memory locations and EEPROM checksum during the power up test sequence. If a fault is found during the power up test sequence, the appropriate error code will be displayed. Possible Causes 1. These errors messages almost always indicate an upper PCA problem when they are consistently displayed. Failures causing these error messages to be displayed are rare. Possible Remedies 1. If the error message is consistently displayed when the unit is powered up, the upper PCA should be replaced. It is possible to see one of these messages displayed intermittently due to external causes. If the units A.C. input significantly dips during the power up test sequence the test could fail resulting in one of these messages being displayed. Treadmills operating on non-dedicated A.C. circuits may see these messages displayed on an intermittent basis.
In other words, you need recalibration in your equipment, I recomend after you make a test for a RAM MEMORY.so contact your service call. I recomend Strong, INSTALL regulator Voltage is cheap about us$15,00 Radio Shak or another Electronic Place.
Thank you in advance , sincerely. Blessing. If you need additional Help, please do not hesitate to contact me.
