Harley Davidson Electronic Throttle Control Problems And Their Solutions

Harley Davidson Electronic Throttle Control Problems And Their Solutions

Harley Davidson Electronic Throttle Control (ETC) problems can frustrate motorcycle owners. Some common issues include throttle lag, unresponsive acceleration, and intermittent loss of power. However, there are solutions available to address these problems.

One possible solution is to recalibrate the ETC system, which involves resetting the throttle position sensor and idle control system. Another option is to clean or replace the throttle body, as a dirty or faulty throttle body can cause ETC issues. Scroll down to get details on Harley Davidson electronic throttle control problems.

1.Limited Performance Mode (LIMP)

Limited Performance Mode (LIMP)

One common issue Harley Davidson owners may encounter with their electronic throttle control is the Limited Performance Mode or LIMP. This mode activates when the motorcycle’s throttle control system detects a malfunction or fault.

When LIMP mode is activated, the motorcycles may be limited, and the rider may experience reduced power and acceleration. It is important to address any electronic throttle control problems promptly and have them diagnosed and repaired by a qualified technician to ensure optimal performance and safety while riding a Harley Davidson motorcycle.

Possible Solution:

You need to know what code is visible on the odometer when you get such a problem. There are solutions for most error diagnostic trouble codes online. For Limp mode, you will usually get the P1510 code. You will get this code if the throttle position sensor (TPS) or twist grip sensor (TGS) fails to perform.

Usually, the wire harness reaches the injectors behind the air cleaner. But a Limp can happen if it touches the cylinder fins between the front and rear jugs. You can tape a wire wiring harness and get a long-term solution from Limp.

2.Power Management Mode

Power Management Mode

A defective ETC can cause a power management failure mode (P1511 error code) in Harley Davidson motorbikes. Usually, you will get a reduced response to grip throttle sensor input. When this problem appears, the throttle grip plate actuator will return to an unexpected position like “idle det”nt” or “lim”-home”.” It will”provide sufficient torque to get around 40 km/h (25 mph) or traffic speed.

Possible Solution:

You need to check the condition of the throttle plate actuator. You may need to repair or replace it if it has any wear and tear. The throttle plate actuator will be available in motorbike shops at around $20 to $25. Thus, maintenance of the ETC system isn’t expensive.

3.Forced Shutdown Mode

Forced Shutdown Mode

You may get a P1512 error code due to defective electronic throttle control. This code refers to forced idle or shutdown mode. Usually, it happens for the failure of one or both twist grip magnetic sensors, TGS validation error, and brake switch failure.

As a result, the throttle control actuator (TCA) gets de-energized, and the throttle plate is forced to gain a “fast idle” “position. “thus, the engine must meet the high idle speed or shut down unexpectedly.

Possible Solution:

You should check if the TGS brake switch works well to avoid forced shutdown mode. As it happens, replacing the TGS brake switch is your only solution. Replacing the TGS brake ignition switch at home can be a little trickier. So, we suggest you call a professional and hand over the responsibility. You can replace the TGS brake switch for less than $50.

4.Throttle Stuck

Throttle Stuck

Dealing with a stuck throttle on your Harley Davidson can be frustrating, but solutions exist. One cause is dirt or debris in the throttle housing, which can be resolved by cleaning and removing obstructions. Another possible cause is a faulty throttle cable or sensor, requiring replacement for proper functionality.

Promptly addressing a stuck throttle is crucial for motorcycle poor engine performance and safety. If unsure how to fix it, consulting a professional Harley Davidson mechanic is recommended.

Possible Solution:

You should check the cable for any wear or tear. Often, older wires may need to be corrected. Also, the wires can wear out. Then, replace it if required. If you find any loose wiring issues, try connecting it. It may solve the stuck throttle problem soon.

If the problem persists, check if the TPS is working correctly. The TPS may have the wrong setting. So, adjusting it should solve the throttle problem.

5.A Jerky Throttle

Harley Davidson riders may face a jerky throttle, which is not only frustrating but also poses potential risks. It can affect the bike’s responsiveness and disrupt the smoothness of the ride. Possible causes include throttle position sensor issues, faulty Sensors ECM, or problems with wiring and Poor connections.

To resolve this, it is advised to check for error codes using a diagnostic tool. If no codes are found, cleaning the throttle body, replacing the throttle position sensor, or seeking professional help may be necessary to address the root cause of the jerky throttle.

Possible Solution:

Firstly, you must ensure that the throttle position sensor is working correctly. Next, check the throttle cable to identify its wear and tear signs. You can replace it to solve the issue quickly. Lastly, repair the intake system after inspecting it if you find any air leaks.

Harley Throttle Position Sensor (TPS) Problem

It is connected to ETC, so it would be better if you knew about them, too. TPS controls or regulates the fuel supply and flows to the engine. Also, it is responsible for direct signal output to the fuel tank injection system. You can identify if the TPS is bad, which leads to ETC problems in these ways:

  • A bad TPS may indicate your bike fails to remain steady when you are idling it. In such conditions, the engine doesn’t get sufficient fuel, and TPS doesn’t report. Hence, it doesn’t for not reporting that the TPS is damaged.
  • TPS may be bad if you cannot get correct fuel readings to the bike’s engine ECU as a rebike. You get your bike idle even if you try to throttle more. Even the bike engine may shut off due to this issue.

There are a couple of causes of TPS problems, such as vibration, excessive operating temperature, and repeated throttle use. The consequences are pretty annoying as you may get poor fuel efficiency economy or restricted engine performance from the bike.
