I kinda wish I would have done the same. That EFI is nice, but I hate, hate, hate messing with electrical systems. HAHA

Oh, Duh

Reminds me...I have a Suzuki GSX1250FA (Bandit), and the EFI always makes me think twice about any long rides. It has never failed, has monstrous controllable torque, and gets me great Fuel economy (at least 40mpg) no matter how I drive it. But more than once I shut it down with the kill switch, then turned it back on with kill switch, and the EFI was all screwed up, stumbling...bad in traffic! So I turn key off, turn back on, start it, and it apparently resets and works fine. Weird. So I never use the kill switch to turn it off if I am not really done with the trip! And yes, I will always use a mechanical carb on any single cylinder bike. Trouble with it... clean it up and put it back on the bike. Done. |

Well, my air intake temperature sensor is bad. I can't find one anywhere online for sale. Anybody out there have a link to one for sale, or know how to get one?

You should read the first post of the thread. The original poster made it home. It just was running rough. Same as a carburetor. As a matter fact, my entire bikes electrical system was grounding out and I still made it home. You’re just wrong. Nobody’s been left on the side of the road by a fuel injection failure here. Many, many people have been left on the side of the road by carburetor failures.. And this wasn’t the thread that we were talking about this stuff in. In this thread, we were trying to help the OP get to the bottom of what was wrong. And he did. Very quickly. Solved in just a few posts.

I've had good luck ordering from csc motorcycles.com but they don't sell hawks. The closest thing they sell is tt250 which is what l've been going by even though there are differences. The problem is I don't know if they make an injected tt250. But csc definitely has the best website - with parts breakdowns.

Yeah, I've looked on CSC. The TT's are carb only, but it looks like they have a AITS for sale that looks exactly like the one on my bike. I'm going to contact them and find out if it will work.

Just an update for everyone. She started throwing even more codes, so I figured I'm getting to the bottom of this. Took everything off and traced the wiring harness from front to back. Turns out right where the airbox meets the frame the the wiring harness was pinched and had a tiny worn spot. I could barely see it. 2 wires were slightly worn in half. I clipped them, reconnected them and rerouted the harness so it wouldn't happen again. She's running like a champ now.
Took me 5 hours to trace it down, but it was worth it. Just letting anybody that's interested know, check your harness before spending money.

I think it is generic OBD 2 code P0112.
Intake Air Temp circuit low. The computer is seeing a short or open in the IAT circuit. Check wires and connectors at the IAT and at the computer. If the circuit is good replace the IAT and clear codes. If that doesn't work the only thing left is computer. I do not know how to clear a hawk. It may be as simple as disconnecting the battery for a while. If not it may require a scanner.

Capacitance inside the EFI computer can retain the settings, and there might even be an EPROM that it loads from during initial "boot". To dump the capacitance and be certain it is reset, hold the power lead to the ground lead for a few seconds (while it is NOT connected to the battery or anything!). This drains any capacitance that could make the thing hold onto codes. This is a great way to reset modules that have onboard coding (EPROM) that loads a factory default instruction list when connected.

Bump.
For the people who dis EFI, there's a reason that there are millions of vehicles on the road with EFI. They run like a charm and when they don't, you're generally not left crying on the side of the road. The ECM/ECU goes into "limp home mode" (LHM) so that the vehicle can still be driven but (in theory) won't damage the powertrain in the process. I'm very happy that I came across this thread. My CEL/MIL came on today and prior to this thread (and the one by SpudRider) I had no idea of how to proceed. Thank you (most of you) for helping the OP (DoomHead) move to solution so quickly. In my case it was as simple as reseating the connector where the harness plugs into the fuel pump. Which I disconnected last week for some reason. Which explaines why the CEL flashed a Morse-code of P0230 0-: IMO this was the worst type of technical problem: operator error. Doh! BTW, SpudRider did a great writeup of the Delphi EFI system. Curious that he wrote it back in 2015. I thought that my 2021 X-Pro DLX EFI was all "new" tech. Spud's thread: https://chinariders.net/showthread.php?t=15675
