Today I got a check engine light (CEL) after leaving a traffic light. While I was waiting for the light to turn green, I noticed that the bike was idling slower than normal. From what I could see it was around 1350 rpm instead of the usual 1500. Immediately after accelerating the CEL came on and went away about a minute later. Here's the codes in order as presented in diagnostic mode: 1: P0193 - FUEL PR SYS ERR 2: 61005 - LOW FUEL SYS ERR 3: P0132 - FRT O2 SYS ERR I think that the last 2 codes were from when I first got the bike. I didn't notice anything abnormal about the bike when those CELs came up. Can anyone tell me what those codes mean? I figured that they'd be in my service manual; I didn't realize that a completely different manual is needed to get code information. Also, I've noticed on here that most people seem to have AFVs in the vicinity of 100. I'm assuming those are the values in the diagnostic mode called "F ADAPT FUEL" and "R ADAPT FUEL". My bike is showing values of 89.0 and 85.5 for those, respectively. I understand that this is a correction from the standard air/fuel ratio, but I see no reason for it. Does anyone know why there would be a 15% correction needed? | ||

Do a search on badweb, there have been several instances with those code combinations. Mike | ||

Thanks, I looked in the other threads about it and it seemed that the P0193 code was often caused by the rider starting the bike prior to completion of the startup-checks. I always wait until it is completely settled down before starting, and this was hours into the ride. Could it indicate a bad fuel pump? It seems if a fuel pump was bad, that it would have low pressure all the time and not just for 3 minutes. The battery is fully charged up and I had it on a tender prior to this ride. | ||

Looking through the board, it seems that people with the same types of codes had problems with their fuel rail pressure sensor and O2 sensors. It seems that there have been a couple of each of those bad according to various accounts just here on bad web. Remember, I am not a tech or anything, all I did was look for post from people with similar problems/codes. I would have the dealer check the fuel rail pressure sensor and 02 sensor. Bobup and Chevycummins had some similar problems, so you may want to PM them also. Just my thoughts. Mike | ||

they changed the entire fuel press. regulator and rail three times already i actually got a new one just cause i told my manager i didn't like the plastic one and i don't trust it.the newest one is made out of metal and is made by a diff. company look into it | ||

Hi Ron. The low fuel error code is just that. Somebody ran out of fuel which also triggered the low fuel pressure error code. The front O2 sensor code seems to be prevalent when the bike is new. Mine did the same. I had the dealer replace the sensor. And I have not seen it since. The AFV... go figure.. We've had discussions of the meaning of those for a loong time. And there's no conclusion. We collected everybody's AFv values and plotted on a curve to see if there was correlation to altitude, temperature and other ambient factors. No go.. There seems to be no correlation. If you do feel that the relatively high correction factor is an issue, contact Buell Customer Service. If nothing else, to get the issue logged. Perhaps they might have some info for you as well. | ||

Thanks for the advice guys. I know that the bike never ran out of fuel. I've had it since 4 miles on the odometer, and I saw the CEL come on for each of these since I've been riding it. Once the bike was around 130 miles on a tank, I'd get gas and that was often before the low fuel light even came on. So maybe I'll call the dealer and see what they say. | ||

P0193 - lo pressure - wait until the rail pressurizes to start the engine. B1005 - lo fuel error - happens to mine too, sensor spec is 850-1400 ohms. When I get that error, my sensor reads north of 2200 ohms... out of range. P0132 - no idea, no experience. BTW, the Electrical Diagnostics Manual has the DTCs explained.

lso, I've noticed on here that most people seem to have AFVs in the vicinity of 100. I'm assuming those are the values in the diagnostic mode called "F ADAPT FUEL" and "R ADAPT FUEL". My bike is showing values of 89.0 and 85.5 for those, respectively. I understand that this is a correction from the standard air/fuel ratio, but I see no reason for it. Does anyone know why there would be a 15% correction needed? Sounds familiar. My bike is in the shop for a similar issue. My front AFV was/is running from 77.5 to low 80s. It's a long story. BMC has been trying to diagnose a RICH condition (leaky fuel injector, intake) vs. a LEAN condition (bad O2 sensor). Both of the aforementioned could be causing the low AFV. The latest word is that the the low front AFV (typically low 80s) is acceptable, based on diagnostics (no abnormal leaks). I am still confused how things can be normal, but the AFV is cutting fuel by roughly 20% to the cylinder? There's more to the whole story, but what you have heard is the reader's digest version. On BMC's defense, I feel the effort has been strong on both BMC's and my local service department to try to figure this whole thing out--even though the results don't quite add at this point. Also, BMC scored big points by volunteering to replace a part that I would have never known was suspect until it possibly caused catastrophic engine damage down the road. | ||

Fresnobuell, I wasn't too concerned about the trouble codes and low AFV until now. Frankly, I was more curious about the AFV than concerned because it seems like the bike runs fine. Here's what I was theorizing about concerning the low fuel pressure: when the bike was idling low prior to the CEL coming on, I was at a stoplight and felt quite a bit of heat radiating from the engine on both sides. It didn't seem like anything dangerous, but combined with the 1.2 gallons of fuel in the frame I think it may have caused a lot of the fuel boiling action that I hear basically every time I shut the engine off. With the fuel boiling like mad, perhaps the fuel pump was having a difficult time sending it to the fuel rail at design pressure...just a guess. What part are you talking about that could cause catastrophic damage? So is BMC telling you that the AFV is what it is, and not to be concerned? | ||

Ron, My bike ran fine too in the early going (I also disregarded this error.) When I learned that the bike could have a leaking fuel injector or similar issue causing a low AFV reading, that's when I because concerned and took it to the shop. Basically, with one year left on the warranty, I wanted to get any problems sorted out before it's on my dime. Yes, the latest word from BMC is the low AFV is what it is. I have already stated that this doesn't really register with me, so I won't rehash that. Can't help you with the low fuel pressure, thankfully that isn't a code ive seen. | ||

When my bike had the P0193 the dealer finally diagnosed it as a faulty fuel pressure sensor. It took a few trips to them to get it fixed but so far so good. If your fuel pressure is too high because of a faulty pressure sensor the AFV will start to go low, I think that once the pressure sensor is replaced the AFV will go back up closer to normal range. | ||

I had an issue with the LFL and CEL coming on at low ambient air temps due to the IC/ECU seeing excessive resistance in the thermistor that is the fuel level sender. The latest reflash for my 09 1125R seems to have cured it. |
