C35L Ser. P232L-0420-9972 KF. 2018 model year. Low Oil Pressure message and Warning Alarm. Removed sensor and tested oil pressure, 60+ PSI. Reinstalled old sensor and ordered new sensor. While waiting for the new sensor NO Oil Pressure and shutdown with Check Engine Light was experienced. Replaced sensor upon arrival and no more warning light or shutdown.

How do I read the stored code and how do I clear code list. KOEO and the 3 quick WOT to read and 10 times to clear does not work on this system.
