I've been having an issue with a random loss of power which is signalled by the rev limiter chevrons flashing red on the TFT display, and a red flashing band around the rev counter. Opening the throttle will provide some revs which sound subdued and staggered, like the bike is going to cut out, and doing so transfers no power (zero) to the bike to move off. Repeatedly trying to open the throttle will just activate the same warning lights again. The ignition will either have to be turned off and back on again to reset, or the bike will need to wait a few minutes with the engine running before power returns on opening the throttle, and the warning lights do not activate. Typically happens when coming towards a stop at the end of a road/roundabout, junction etc. The bike is a 2023 937cc model, it is the SP version. Had the full Termi race system fitted which removes the cat and is then reprogrammed with the Ducati Racing Evo programme, which was done when the bike was registered as new at the Ducati dealership it was purchased from. Other than that its never had any further flashes, tuning, dyno work done. Its never had any other mechanical, electrical or engine modifications either. The bike has been kept up to date with servicing. It is an intermittent problem and can occur at any time, regardless of either sport, road or wet mode, it doesn't matter if you shift manually or with the quick shifter, same issue will occur. I've tried taking the baffles out of the twin exhaust which has made no difference. I've tried cleaning some of the carbon buildup in the silencers, also no difference. I've had it back to the dealer who cant find a fault, and a local independent garage which has Ducati diagnostic tools, and neither could find any fault or make any suggestions. I've not been updated about any updates or recalls needed either. I had a hunch it could be some issue with a sensor reading engine emissions, or something of that nature. Possibly electrics, but nothing from the diagnostics suggested these. Super frustrating as the bike is light, nibble, and it rides & sounds fabulous. Wondered if anyone has come across same issue or might have any suggestions regarding the issue?
Sounds like it is related to the Throttle Position Sensor or the Accelerator Position Sensor. Given it's intermittent nature maybe a clean of the connector pins for each could solve it.
@James kay, I have been told, this is a known issue across several of the Ducati range that uses the 937cc engine which I’m surprised your dealer didn’t find in the knowledge base. Basically, the bike loses it’s memory and can’t tell what gear it is in, resulting in a loss of power and the rev counter lighting up as you describe. The recommended course of action is to carry out a gear reset followed by re learning the gears (as in telling the ECU, this is first, this is second, this is third etc.) Your independent might have the diagnostics to do this but they might not. You need to have the conversation. Andy
