 Hello everyone!

I recently bought a 2016 CVO Road Glide Ultra with 24,000 miles. However, during my first rides, the check engine light and the engine overheat indicator came on. I noticed that the indicators appear as soon as the engine warms up and the RPM drops to 900–1000. I connected a diahnostic tool (Twin Scan 4), and it detected the following error codes:


I checked the fuses and wiring — everything is fine, with no visible damage on the harnesses or connectors. I replaced the oxygen sensors and the engine temperature sensor, but there was no result. Now I’m thinking of replacing the ECT sensor.
Our local HD service is very busy, and the earliest appointment available is only in mid-September. I’d really like to figure everything out on my own. I’d appreciate any ideas or advice from the CVO gurus.

Wow!  Your local Harley-Davidson dealer can’t get you in for basically a MONTH?
Dealers I’ve dealt with over the years could always “work-in” a repair job - they could push-back another exhaust install a couple hours or so…

The local shop can only squeeze in four bikes at once. They’re much happier bolting on performance kits, doing tunes, and installing LED lights — chasing down gremlins in old Harleys isn’t exactly their idea of fun.

Just curious, how does it run?
What did the oxygen sensor look like when you replaced it? Was it good ? Did it look black?  Or brown?
If the O2 sensors look good
Most likely root cause:
   •   Shared ground or fuse issue in the main engine sensor harness.
   •   Loose or corroded ECM connector (especially on the left side of the bike under the seat).
   •   Low system voltage or bad battery ground causing multiple “low” or “open” readings.

You have a lot of different codes, Some of those codes could be old. Personally, I would clear the codes and see what comes back.  If they all come back, it’s probably a bad ground or corroded connector causing low-voltage.
