@@LowCountryHarleyDavidson Doc it’s not so much the skills or even the knowledge. It’s that you have a passion and actually care. Too many techs ( not just Harley ) don’t care and they’re bothered by customers so much they can’t focus on the actual task. Not bothered as if a customer is haggling or calling all the time. They simply are bothered by the mere fact of just bringing the bike in and asking questions. They’re annoyed by that. Instead of taking the approach of “ what’s the problem with the bike? And wanting to find a solution “.

Doc, Love your videos. My wives 2001 Heritage had a cough occasionally and was hard to diagnose. Finally figured out that it was when the gas tank was lower than half full. The corrugated gas hose in the tank stretches after a while and the hose rubbed on the side of the tank and got a small pinhole in it. It was a little tricky to figure out. Thought some of your listeners might want to know about this issue that I have seen twice on Heritage before. Keep em coming.

[@larrybrown441]

Been there many years ago on my 03Ultra. Pulled off interstate and tried to die at exit stop sign, hotter than normal. I believe it was running very lean at the particular speed we were traveling. Took it a little slower and rest of the trip home was ok. Checked resistance of TPS once we were home and sure enough it had a definite bad spot. Did a Thundermax tuner last year decided to replace it again as we are around 138k now. Kept the old one as a spare as it is still good but feel better with a new one on it. We thank you for your continued support and info.

[@LFGM24]

Doc is the man. What else is new? He’s awesome. Now I will say as much as I love Harley, I hate when they use plastic on stuff like this. Especially the gears. I be mean this isn’t an Arrma RC or a Maxxis. This is a Motorcycle and the throttle is something that’s being constantly used…. Lol. HELLO 👋🏼 !!!! You think you may want to go with a more durable material there?? I mean goodness. Using metal there doesn’t mean you’d have increase the price on the bike by $400. Because they’re already overpriced as it is. But anyhow that’s a small rant on Harley but I love Doc.

Great vid doc, thanks. Exactly what I had concerns about, but my2015 - 1200 only has about 15k miles. so think its unlikely to be wear on that sensor. Has a ragged patch, just as throttle opens a tiny bit. Realy dosnt like ticking along steady around town. Fine under power, and everywhere else, just that first tiny touch. S.E tuner cables should be here this week, so will plug it into record mode for a while and see if that shows where the issue is. Tks again.

Hey Doc...Awesome videos and thank you for taking the time to do that for all of us Harley Riders. Quick question: 2003 Harley Road King EFI FLHRI Replacing the TPS is pretty straight forward so my question is...Is there any calibration or setting for this TPS or is it a "bolt on and go"??? I don't see anything about Calibration so Im assuming there is none but I wanted to run it past the Guru first..

Should be a plug and play with stock ECM. Buells and ThunderMax have to be calibrated...Doc

[@shanetowne6530]

On my 08 roadking I had a whipe out and it started to idle high but its electronic so no adjustment. Turns out if i turn it off with more than 0 throttle it needs to be reset. This video was my first thought but after digging further I found out it wasn't the sensor.

[@sportster88]

Thanks for the info Doc! I have a 2020 Softail Standard that has an overly stiff throttle position sensor. It wears out my wrist after 1/2 hour of riding. I changed handlebars and decided to disassemble the TPS to see what was going on. If I ruin it I"ll buy another one. I'm trying to figure out how to remove the splined cog on the end of the sensor without destroying the sensor. Do you have any idea how to do that?

[@LowCountryHarleyDavidson]

Thanks for trusting and reaching out to us at Low Country Harley-Davidson. This is not a simple diagnosis. I would start first with battery check. Condition and connection. Older than 4 years replace. Have someone check charging system. Spark plugs and wires depending on mileage then fuel filter…Doc

[@GenOakFab]

I've got a 2009 street glide and recently it went into limp mode and has a surging idle with these codes P1511, P1514, p2105, P2135. Do you think this would come from the TPS sensor going bad? thanks! Great Video!

More likely the pins and connections in the connector to Throttle Control Mech. If you are lucky all you need is to replace the female connectors in the connector with the newer updated parts.

[@LowCountryHarleyDavidson]

Most of the time on recent models it is a clitch. It occurs most of the time with riders who shut off motor with the handlebar switch while their palm has the throttle rolled on a bit. You should still have it checked out…..Doc

[@skybudd]

Heya Doc i have a 2019 xl1200ns with a P0122. Any pointers on how to calibrate a TPS??

[@LowCountryHarleyDavidson]

Not sure what you mean by calibrate. Usual issue is owner turning off bike with handlebar off switch while slightly rolling throttle ( not knowing he is doing this) so the bike ECM remembers where throttle plate is. But when turning on bike the TpS does not match last known information. So turn on bike without touching throttle. Wait 20 seconds. Turn off 20 seconds. Repeat 2 more times. All will be calibrated

[@skybudd]

[@LowCountryHarleyDavidson]

Start by readjusting your throttle cables. If you have chsnged the handlebars you have a throttle position sensor wire problem. Follow all the wires. If you have changed the air cleaner. You might have a leak. Maybe a un supported throttle body so an air leak at manifold seals…..Doc

[@LowCountryHarleyDavidson]

My first thought is an intake seal is leaking and allowing air in. Could also be the IAC pintle has excessive carbon on it or is failing. And of coarse many other possibilities. Fuel filter, holes in fuel line in tank, Not a correct tune, bad Engine temp sensor.....bring it to your local expert and them check these out.....Doc

This usually indicates an air leak or a VOES going bad....Doc

Ran codes on my 2011 street glide one popped up no rsP

[@michealpeek411]

Had another one popped up P1353 the motor turns over but does not start

Front Cylinder no combustion detected. Could be as simple as a loose spark plug wire, a failing O2 sensor, a crazy short exhaust with no baffles, a dropped head valve...The list is endless. Take it to your local dealer.....Doc

Typical potentiometer. It'll wear out where it is set the most.

Hi Doc i m using road king 2016 model, i drop my bike at work shop for change oil and service, mileage meter was 9289, when i collected bike meter shows 16.5k, i complaint to work shop they said ECU has been remov to check another bike for 2 days and reinstall back that why mileage has been change they are trying to fix the problem but no success, i like to know whats cause and solution to bring back actual mileage Regards now facing problem with mileage on meter, actually mileage is 9200

[@LowCountryHarleyDavidson]

The ECM has the mileage in it. The other bike has the higher mileage. The speedometer after 35 miles reflects the ECM mileage of the higher miles...you can not turn back the hands of time...new speedometer needs to be ordered ...Doc

@@LowCountryHarleyDavidson i much appreciated your feedback, with high mileage ECM will reflect higher mileage if i change new speedometer or i have to change new ECM ? Looking forward your response please Regards
