you do not have an answer
I'm not sure where you were under the impression I don't have an answer when I haven't even had a chance to respond yet? I was field service for cat before going independent. Anyway if you have a drive motor speed sensor fault code it is usually either a faulty sensor or a wiring harness problem causing the ECM to not read proper speed sensor signal. In some cases it is just a matter of it being out of calibration which caterpillar ET software will need to be connected on a laptop to run the calibrations. Caterpillar ET software is the dealer diagnostic software that caterpillar uses. So if the sensor and wiring all tests good you will then run recalibration and if there's still a problem in some cases you may need to reflash or reprogram the ECM software to reset the system to factory settings. Please let me know if you need more help and take a moment to rate my answers as that is how the site credits my time for helping on the site. Five-star ratings and bonuses are always greatly appreciated
