XB9S 2002 –Can Error 14 (eng Temp too high) cause the ECU to stop the engine running

[CrashBurnFly]

Symptom. 1 mile into a ride with engine still cool and bike coughs, engine warning light comes on so head home to check.
At home engine turns over, fuel pump runs but no firing. Bloody thing, leave in garage and go for ride on 1911 Triumph as that always works...
Next day connect ECMDroid and No Current Errors and a just 1 Stored Errors: “14 Eng Temp too high ... or to ground..”.
Clear code and watch engine temp (Cylinder Head Temp Sensor (CLT)) via ECMDroid slowly rise as bike warms up and all works as expected and so CLT seems to be working OK.
Use Droid to test fan and works OK. As all now seems OK which is annoying as we all like to find the fault to know its fixed rather than just lurking waiting to reappear another day.
If the ECM gets a Error 14 does the ECM shut down anything that would stop the bike running?
All thoughts appreciated as I’d like to understand what happened.

A 2002(?) XB9S?

A code is a clue to what circuit or sensor the ECM is getting a reading outside of normal parameters. Having or clearing a code won't make a difference in how the ECM reacts to that signal.

If the ECM thinks the engine is overheated, it can stop one cylinder from firing, lower the RPM limits, and, even kill it.

The sensor, or circuit is telling the ECM it's overheated, causing the code to let you know where to look.

Look at the whole circuit for chaffing, ohm the wire between the sensor and the ECM (it's in the rear head), check the reading with live data on ECMDroid as you heat it up with a heat gun, or just replace it, they're about $80

Good luck and post up what you find. Pics of the Triumph please:eagerness:

Hi Cooter - many thanks for the detailed response that answers all my questions. I will explore and post back findings.

The solution to my issue was to replace the temperature sensor - Thanks to all that helped.
