Experiencing code P0107 on your Harley may manifest through various common symptoms that can help you identify and address the issue efficiently. Here are three key signs to look out for:

  1. Check Engine Light:

One of the most noticeable symptoms of P0107 is the illumination of the check engine light on your Harley's dashboard. When this light comes on, it's a clear indicator that there's an issue that needs attention.

  1. Reduced Engine Performance:

If you feel like your Harley isn't performing as smoothly or powerfully as it should, P0107 could be the culprit. Reduced engine performance, such as sluggish acceleration or rough idling, can be linked to this trouble code.

  1. Poor Fuel Economy:

Another common symptom of P0107 is a noticeable decrease in fuel efficiency. If you find yourself making more frequent trips to the gas station or notice that your mileage per gallon has significantly dropped, it could be due to this issue.

Possible Causes of P0107

Let's look at the possible causes of Harley Code P0107.

A common culprit is a faulty MAP sensor, which can lead to incorrect readings and trigger the trouble code.

Additionally, wiring issues can also contribute to the P0107 error code on your Harley.

Faulty MAP Sensor

A faulty MAP sensor can be a common cause of the P0107 trouble code in Harley motorcycles. When your MAP sensor malfunctions, it can trigger the P0107 trouble code, leading to performance issues and potential breakdowns.

Here are three key reasons why a faulty MAP sensor might be causing your Harley's P0107 code:

  1. Dirt and Debris Build-Up: Over time, dirt and debris can accumulate on the MAP sensor, affecting its ability to accurately measure air pressure. This build-up can lead to incorrect readings and trigger the P0107 trouble code.
  2. Electrical Malfunction: If the electrical connections to the MAP sensor are loose, corroded, or damaged, it can disrupt the sensor's performance and cause the P0107 trouble code to appear.
  3. Sensor Wear and Tear: Like any other component, the MAP sensor can wear out over time. If the sensor itself is faulty or damaged, it may no longer provide accurate air pressure readings, resulting in the P0107 trouble code being triggered.

Wiring Issues

When troubleshooting the P0107 trouble code in your Harley, wiring issues can also be a significant culprit that may need to be addressed.

Faulty wiring can lead to incorrect readings being transmitted to the MAP sensor, triggering the P0107 trouble code.

To tackle this issue, start by visually inspecting the wiring harness for any signs of damage, such as fraying, cuts, or exposed wires.

Make sure that all connections are secure and free of corrosion.

It's important to check the wiring for any shorts or opens that could disrupt the signal from reaching the MAP sensor accurately.

Using a multimeter, test the continuity of the wires to pinpoint any potential areas of concern.

If any damaged wiring is detected, repair or replace the affected sections as needed.

How to Diagnose P0107

To diagnose P0107 in your Harley, start by checking the wiring and connections to the Manifold Absolute Pressure (MAP) sensor. Here's what you need to do:

  1. Inspect Wiring: Begin by visually examining the wiring harness connected to the MAP sensor. Look for any signs of fraying, damage, or loose connections. Confirm the wiring is securely attached and free of any corrosion.
  2. Test Voltage: Using a multimeter, check the voltage going to the MAP sensor. Compare the readings to the manufacturer's specifications to determine if the voltage levels are within the correct range.
  3. Check Sensor Functionality: If the wiring appears to be in good condition and the voltage is correct, the issue may lie with the MAP sensor itself. Consider testing the sensor's functionality or even replacing it if necessary.

Steps to Repair P0107
