The major Harley Davidson electronic throttle control (ETC) problems include limited performance, clogged throttle, DTC codes, loss of power, and unresponsive throttle. And these problems can cause many other minor issues. <\/strong> <\/p>\n\n\n\n

From 2008, Harley-Davidson motorcycles are designed with electronic throttle control. Since then users have made many complaints. <\/p>\n\n\n\n

With time, the ETC itself can be damaged and cause various driving issues. So, without wasting time let\u2019s explore the issues and their solutions.<\/p>\n\n\n\n

Troubleshooting and Fix for Harley Davidson Electronic Throttle Control Problems <\/h2>\n\n\n\n

As mentioned earlier, a faulty ETC can cause some difficult occurrences that can prevent you from riding your Harley-Davidson. <\/p>\n\n\n\n

So, let\u2019s get a closer look at the major ETC problems, their causes, and the possible troubleshooting and fixes. <\/p>\n\n\n\n

1. Clogged Harley Throttle<\/h3>\n\n\n\n

One of the most common problems that can come with a Harley electronic throttle is a clogged throttle. There are several possible causes for a jammed throttle control. <\/p>\n\n\n\n

In most cases, the ETC on a Harley-Davidson gets stuck because of excessively accumulated dust and debris between the throttle tube and other moving parts. <\/p>\n\n\n\n

There is also a possibility of a broken, corroded, or stuck cable inside the throttle. So, start by checking inside the throttle to see if it is dirty, and if so, then clear them all. <\/p>\n\n\n\n

Also, check the wires to see if they need to be reconnected or corrected. But if the cable is too old and corroded, you’ll likely need to replace it. <\/p>\n\n\n\n

2. Poor Acceleration <\/h3>\n\n\n\n

Acceleration issues are another common problem triggered by the Harley electronic throttle control. It happens when the throttle is not responding or having issues to respond properly. <\/p>\n\n\n\n

If it is, then the reason might be a loose or disconnected throttle wiring or a faulty TPS. So, check for loose wiring and reconnect it if needed. <\/p>\n\n\n\n

Then recheck the throttle if it is working. If it is still unresponsive, check the TPS if it has the right setting. Otherwise, reset it or replace it if necessary to solve the problem. <\/p>\n\n\n\n

3. Error Codes <\/h3>\n\n\n\n

This is another most common problem that most Harley Davidson enthusiasts face due to a bad ETC on their bike. <\/p>\n\n\n\n

When the ETC or any part of it like the grip sensor, brake sensor or actuator goes bad, the ECU will trigger multiple error codes. <\/p>\n\n\n\n

P1511 and P1512 are the two most common Harley error codes related to the electric throttle control. <\/p>\n\n\n\n

If the throttle actuator or the TGS gets the wrong position or goes bad due to internal contamination, these codes will appear on the screen. <\/p>\n\n\n\n

These errors can cause several difficult consequences for your bike. There might be no acceleration, or no throttle response. <\/p>\n\n\n\n

It can also activate the home-limp mode, power management mode, and even the power shutdown mode. <\/p>\n\n\n\n

As a result, the engine on your Harley-Davidson will start idling, stalling, or misfiring. In some cases, the engine can also shut down.  <\/p>\n\n\n\n

To solve these issues, check your Harley throttle actuator to see if it is positioned correctly. <\/p>\n\n\n\n

If not, then fix it properly. But if that actuator gets too much contamination, then it’s better to replace it. <\/p>\n\n\n\n

In addition, you should check the grip sensor and brake sensor if the error codes persist. <\/p>\n\n\n\n

If you find any of these sensors is faulty, then you’re suggested to replace the bad one.<\/p>\n\n\n\n

Harley throttle position sensor or TPS is an important part of the vehicle’s ETC. So, if the TPS gets faulty, it will cause some electric throttle control problems as follows: <\/p>\n\n\n\n
