Didn't even think to look there... I didn't start having problems till I hooked up my lights and my seat been pushing down on it all making it open... your a hero lol
I just want to say thank you, thank you, thank you! I was having trouble not being able to reset my TPS codes and one of your trouble spots was the problem! The ECM connector was not making a good connection. Evidently when I replaced my battery I must not have snapped the locking clamp fully and it loosened up. Great video for troubleshooting this issue
Having the issue on my 08 sg. Keeps going into limp mode all of a sudden. I found this video and gonna dig into the things u mentioned. Thanks for sharing brother.
@@drtomasdds that was exactly what was wrong with mine. I took it apart and cleaned all the pins and havent had a issue since. Its a shame u didnt try yourself cause i know those dealer mechanics can really rack you. Good luck bro, hope u get her fixed.
Just wanna say thank you you were thorough and you answer the question that I need to try to find out because I was having that limp mode on the 2009 and a couple other things that you brought to. My attention was really helpful. Thank you very much for making the video to help others.
Thank you, I had the same issue. I stalled on the freeway and couldn't clear the ECM code and rode the bike home with a rough idle. I watch your video, re-seated the emc connectors and was able to clear the codes. readjusting my connections under the seat now.
Had a p1510 & p2138 code that wouldn't clear on my 08 Ultra. Pulled the throttle body plug apart behind the air filter, put some die-electric grease on it, put it back together, codes and engine light cleared a went off.
Having the same issue. Bike just went into limp mode on the highway. Scared the shit put me. 😂. Pulled over and it started back up. Finally got it home after three more times. Found this video and going home today and try it.
I was having an issue with the throttle by wire and it ended up being a issue with the throttle body/ entire fuel injection system. Was able to replace that whole unit behind the air filter there for $250 about oem from Harley and it fixed my problem.
Awesome video. I'm having some codes being thrown close to Daytona Bikeweek. Now I'm in panic mode. Another key factor is making sure your battery is secured...
I’m gonna use this to hopefully solve my issue. Thank you for your research and helping with explaining all the related electrical connections for the throttle. Crossing fingers 🫰🏼
The connector in the bars also corrodes causing problems , the S E twist grip sensor does not have the connector and has longer wire , or you could cut the connector out and solder longer wire on insulated well . Some times you can unplug and plug in the throttle body connector 2-3 times and it gets better contact , if thats the problem . The ecm plugin , if you noticed has a bunch of pins , easy to bend , fold over and break , or bend over and short circuit . I used the S E twist grip sensor when I put LA chopper 10" twin peaks on 08 ultra the wire reached all the way to the plugin with just a little slack left . I also bought a spare throttle body off a 2010 wreck , they had a video of it running , out side of the injectors and map sensor , the electronic part of the throttle body is not repairable , its a throw away .
just installed new 12 inch yaffes on my UC. Everything works except no throttle. Codes P1510 and P2138. Was wired by HCC, who do it for a living so, I really don't think it's an internal wire issue. I will certainly check those 2 recommendations when I get home today. Thanks
man you have a bad ass! bike, I have an 07' with throttle not responding after I ran it for a while doing some parking lot tight u-turn practice so dont think this will resolve my issue but it gets me looking in the right places.
Thank you my low rider s loses power at 3,500 rpm when wide open hopefully it will be something easy to fix never had that problem until after it was tuned
Thanks for the video! I believe what I am experiencing is due to the limp mode issue with eratic idling, losing throtle connection when I hit a bump, etc. Anyways, I have another issue where I turn on my ignition and I do not have power, intermittently. I may see the lights flicker and then no power. It seems that I don't have a complete circuit with the ignition. I do have a new battery and I have checked all fuses and relays. I'm wondering if the issue you are describing you are having with the ECM connection also had you not able to close the circuit when you turn on th ignition. I get it to close the circuit after I bounce on the seat a few times which is why I thought of the ECM connection, maybe not closing the loop. Thanks in advance!
I'm wondering if my Ultra Classic has the same problem. What happens is I'll be riding down the road and suddely the engine goes to idle and the throttle will not increase rpm. So I pull over to the shoulder of the road ,restart my bike and it seems normal. But then it happens again in a few miles. Also I've noticed my engine light coming on for about 10 seconds when I start the bike. Thanks for the video. I'm going to check all the areas you mentioned here.
How you doing did you fix your problem on your bike having the same problem already change the connector plug all in the air filter and it's still doing the same thing do you have any ideas what can you do
@@walteralvarado3640 I had a new throttle sensor installed by a mechanic friend. He charged me 300 dollars parts and labor. If you want to do it yourself you can find that part on Amazon, I think.
When you had the issues what exactly what’s the problem I have a 09 road king , starts fine,idles fine, pull off mite make it a block seem like throttle response dies, bike never shuts off, just idles
Man I’m still wondering what happened to my bike. I try to open the throttle fast and it bogs out I have to take it easy or else it won’t go but once it catches it’s good just can’t fully open throttle fast
Thanks Bro! my bike will start and shut off 2 seconds later...moving the throttle dose not rev the engine at all. code P1512.. any help will be greatly appricated
I chose that exhaust for 2 reasons and either reason had to do with performance. I wanted something that looked good and sounds radical! And I think I got it with that pipe. LIKE SHARE SUBSCRIBE!!!

Just had same issue on my 08 sg last week. I never thought to check UA-cam. It’s at dealer now $$$.
@@drtomasdds that was exactly what was wrong with mine. I took it apart and cleaned all the pins and havent had a issue since. Its a shame u didnt try yourself cause i know those dealer mechanics can really rack you. Good luck bro, hope u get her fixed.
That's a clean ride man. I disconnected and cleaned the ecu and cable by the air intake and the bus we went away and started right up
So three points of possible issue. Voltage to the ECM caused by an aftermarket seat. Appreciate it

Exactly what I needed! Thanks for taking the time to make the video!

Its in that large connector under the seat.
@@watsonmotorsports8753 but is that ECM connection causing no power when you turn on the ignition?
Yes, helpful

Hey Michael Joe Smith, I've got an 08 ultra classic doing the exact same thing you said yours is doing. What did you wind up doing to fix it?
@@waylonshrewsbury652 I ended up having a new throttle sensor installed. Cost about $300 including labor. Bike is doing fine now, knock wood.
Awesome. Thanks
How you doing did you fix your problem on your bike having the same problem already change the connector plug all in the air filter and it's still doing the same thing do you have any ideas what can you do

Dear, the code 2138 road king 2008 appeared. Do you have any tips for a solution?
Damn Nice Bike/;-)))
thanks
Great video brother very detailed thanks
Nice pipes, if you don't mind what are those ? 👌👌

Amazing how some people spend thirty thousand and have a limp mode problem

IF I purchased a new ECM can I just plug it in and replace it ? Or does it have to be taken to a dealership??
When you had the issues what exactly what’s the problem I have a 09 road king , starts fine,idles fine, pull off mite make it a block seem like throttle response dies, bike never shuts off, just idles
What are some other common issues you would run into on the early road king? I’m about to purchase a 95 Road King
I would look for a twin cam which is a 2000 and newer model.
Man I’m still wondering what happened to my bike. I try to open the throttle fast and it bogs out I have to take it easy or else it won’t go but once it catches it’s good just can’t fully open throttle fast
2012 fltrx I'm having same issue, throttled it out and it died, I thought I blew the motor but.?. I'm searching if you get info pass along
💯
are all fuel injected bikes throttle by wire or do some still use a cable?
Harley touring models 2008 and after
What pipes are them nicccce
Covington
I have a 2010 road king classic and I had the same problem that throttle response I have none it will idle but it won’t have no throttle
How do you know if the ECM reset after turning on/off 4x ?
Codes are cleared.
@@watsonmotorsports8753 Mines not showing any codes , trying to determine if mine is going Stupid
Thanks Bro! my bike will start and shut off 2 seconds later...moving the throttle dose not rev the engine at all. code P1512.. any help will be greatly appricated
Twist grip sensor could be bad. Check everything I showed in the video.
@@watsonmotorsports8753 Thanks Bro💯
How do you clear ecm
How does the 2 into 1 shorter exhaust work for you?
I chose that exhaust for 2 reasons and either reason had to do with performance. I wanted something that looked good and sounds radical! And I think I got it with that pipe. LIKE SHARE SUBSCRIBE!!!
what were the symptoms ?
Misfire and sputtering just not running right!
What kit did you use for your 26
American Suspension
Ok thanks
Is it getting reset if the key is not there?
I believe key fob must be present for ecm to read.
I have a 2008 Harley Davidson Fatboy, it's getting high rpm once it's start...it's a esp injection what should I need to check first?
Throttle by wire? Considering there are no wires on your throttle and the bike is fuel injected, I think you mean electronic throttle.
The wire is on the twist grip sensor and electronically sends signal
@@watsonmotorsports8753 lol
Don't even know what your riding, called your road king, road guide 3 times
Lol!!! I got more toys than I can keep up with so can I hire you to keep things in perspective?
@watsonmotorsports8753 how much you paying?
Shit that might be my issue
💯
Great video. Thank you!
