Harley Code P0107 – Potential Causes And Solutions

If your Harley Davidson motorcycle is having trouble, such as stalling or dying at a light, and you notice the diagnostic code Harley code P0107 showing up on its system, it’s likely an issue with the Manifold Absolute Pressure (MAP) sensor circuit. To properly diagnose this problem and identify a feasible solution to get back out riding again safely, troubleshooting must be done to understand what caused it in the first place.

Symptoms of Harley Code P0107

If your bike is exhibiting Harley Code P0107, you may be experiencing engine stalling or cutting out when the motorcycle is at idle speed. Additionally, starting up might become difficult and the idle could feel rough or inconsistent. There could even be a drop in fuel economy; furthermore, accelerating can potentially cause hesitation or lack of response from the motor.

Troubleshooting Harley Code P0107

Before replacing any parts, ensure you properly diagnose the issue if your Harley Davidson motorcycle is exhibiting symptoms of Harley Code P0107. A correct diagnosis will save time and money from needless repairs, so take that first step in troubleshooting.

To detect Harley Code P0107, a diagnostic tool like Power Vision (PV) can be used to read the codes and assess whether or not the Throttle Position Sensor (TPS) is functioning correctly. If only one code appears on PV – that being P0107 – then it’ll suffice to replace the MAP sensor in order to solve this problem.

Nevertheless, replacing the MAP sensor may not always be the solution. If both the cam and MAP sensors have been changed without resolving the issue, it could mean there is a defective ground connection somewhere in your vehicle.

If the bike has been receiving error code P0107, then it’s probable that there is a problem with either the 5V signal voltage or its ground connection. To rectify this issue, we recommend closely inspecting the grounds at the bottom of your tank bib – where four to sixteen gauge wires are linked to one of your loom hold-down bracket bolts; as corrosion and fuzziness in connections can cause this particular trouble.

Replacing Parts for Harley Code P0107

Before you opt to insert new components in an attempt to correct the Harley Code P0107, it is of utmost importance that you appropriately diagnose the issue. Taking this step will not only spare your valuable time but also prevent any unnecessary monetary expense.

If the defective MAP sensor is identified as the source of your issue, then replacing it should put an end to any further problems. Unfortunately, if after swapping out the part there are still issues present, you may need to replace either the fuel pressure regulator or crank sensor. It’s important that these components are not replaced without a thorough diagnosis as they can be quite pricey and cause needless spending.

Preventing Harley Code P0107

Maintaining your Harley Davidson motorcycle’s performance and longevity is critically important, especially when it comes to tackling Harley Code P0107. To help combat this issue, regular maintenance like changing the fuel filter every 10,000 miles can prove immensely beneficial. Also make sure to regularly inspect and clean the ground connections–this simple step can effectively prevent electrical problems such as Harley Code P0107.

Conclusion

Harley Davidson owners can feel overwhelmed when they experience trouble code P0107; however, with some diagnostic diligence and the right troubleshooting steps, this issue is solvable. The most frequent fix for this problem involves swapping out the MAP sensor, but you may also want to inspect and cleanse any ground connection to aid in avoiding it from happening again.

To protect your Harley from electrical issues like P0107, regular maintenance and ground connection checks should be carried out. If you’re unsure about how to identify or resolve the issue, it would be wise to consult a certified Harley Davidson technician for professional advice.

FAQs

Here are some FAQs related to Harley Code P0107:

What does Harley Code P0107 mean?

You might experience engine stalling or cutting out, difficulty starting up your bike or lower fuel efficiency – all of which can be traced back to an issue with the MAP sensor circuit.

What causes Harley Code P0107?

Issues with Harley Code P0107 can typically be attributed to a malfunctioning MAP sensor, low fuel pressure regulator performance, or poor crank sensor calibration.
However, these problems can often be avoided by following the recommended service intervals such as replacing your bike’s fuel filter every 10,000 miles. Regular maintenance is key in ensuring reliable operation and preventing this type of issue from arising.

How do I troubleshoot Harley Code P0107?

If Harley Code P0107 has you stumped, a diagnostic tool such as Power Vision (PV) is the perfect solution for accessing and analyzing codes. The PV will show only one code – P0107 – which indicates that the Throttle Position Sensor (TPS) needs to be replaced.
However, if replacing this part doesn’t resolve the issue, then it’s time to investigate other potential problems: checking or cleaning ground connections; replacing fuel pressure regulators or crank sensors may become necessary in order to solve your problem effectively.

Can I prevent Harley Code P0107 from occurring?

To reduce the risk of Harley Code P0107 appearing, routine maintenance like replacing your fuel filter every 10,000 miles is necessary. Additionally, it’s also important to stay atop inspecting and cleaning up any ground connections that may be faulty as this can help ward off electrical issues similar to P0107 from cropping up.

Should I replace the MAP sensor if my bike throws Harley Code P0107?

If your bike is exclusively displaying the code P0107, then exchanging out the MAP sensor should solve any issues. If it continues to be a concern after switching out the MAP sensor, you may need to inspect and cleanse the ground connection or substitute other components such as the fuel pressure regulator or crank sensor.
It’s critical that you have accurately identified what might be causing this issue prior to replacing any pieces.
