P2185 hist curr ect sensor high error code
On my 2016 Road Glide, I installed Rinehart true dual exhaust a few months ago. Two weeks ago I installed a Power Vision and Arlen Ness Clear Sucker AC. I used the closest base tune from DynoJet (high flow AF and Rinehart slimline duals) and overall runs well, but the engine light came on. The error code showing on the PV is what's in the title. I tried to clear it out but the keeps coming back.
This past weekend I attached the PV and tried the autotune option, took it out for an hour or so with different types of riding (freeway and city traffic), assigned that map and am still getting the same error code (and engine light). When I get home this weekend I'll go for another spin and see.
Doing a trusted Google search - it has something to do with the engine coolant? When I was researching it that night after my ride i was also packing for my trip (I travel almost every week) so forgot to check the oil level - I'll do that this weekend when I get home.
Any suggestions? I'm obviously new to the PV and how to program it (I put a PCIII on my 05 EGS and that went pretty smooth (Thunderheader and AN Big Sucker), but the standard map seemed to work fine). I loaded it on my laptop but there are so many options I wasn't sure where to begin.
Thanks!

throwing out some generic stuff
working on the machine did you disturb the wiring to the sensor.
1. bad sensor/out of range resistance/shorted
2.open ground wire on the sensor
3.short in 5vdc supply between sensor and ecm
4.ecm issues
some codes cannot be erased with a reader, must use a scan tool/programmer. these codes will usually erase themselves after so many restarts without issue.
reach out to mr. maxheadflow or mr. grbrown as they are electronic experience with hd systems, i ride gravity, it never fails.

When a typical 2 wire temp sensor circuit is open, it goes high to the 5V reference. You have an open in one of the two wires, a bad connection or a defective sensor. The short is possible but least likely.
This is assuming it is not a PV glitch. Load your stock tune and see if it goes away - that will tell you.
If it's happening right away, obviously the bike is not too hot.

I'm going to cross my fingers, try the auto tune and see how that works.
Thanks!
Youre welcome! Thanks for following up!

My mistake was trying to auto tune from the pre created map.
hope that helps.

Very common experience using canned maps, especially non OEM (calibrated Injectors) calibrations made from public vehicles which are not anywhere near the same causing variables in fueling and timing. Once performance starts going up the engine requires more precise fueling and ignition timing. This is why recalibration (tuning) makes such a dramatic difference.
The above said, street tuning can produce a pretty good running bike, as long as strict tuning guidelines are met to get to, and spend enough time for the system to learn throughout ALL possible running conditions.

P2185 Code:
Hello Everyone,
I work as a technician with PV and can provide a very easy solution for this. If you are getting the Code P2185 ECT Open/High, it is because you are using the wrong tune. If you have an air/oil cooled bike, you have no ECT (Engine Coolant Temp) sensor. Using a code for the Twin Cooled, Rushmore bikes means that the tune thinks you have an ECT sensor when you don't, and it throws that code. If you need the appropriate tune for an air cooled bike, use the tunes that have a lower case "a" in the middle, after the engine size.
e.g.- 15T103a02301 instead of 15T103002301
