What Can Cause This Code?

The P1632 code can be triggered by various factors. However, it is most commonly associated with electrical issues, particularly relating to the motorcycle’s battery. A weak or dying battery, poor battery connections, or low voltage can all lead to the activation of this code. Additionally, problems with the speed sensor or ignition switch may also cause this issue.

How To Troubleshoot Code P1632

Battery and Connections Check
- Inspect the Battery: Check for any signs of aging, such as swelling or leakage. Use a multimeter to ensure the battery holds a charge adequately (12.6 volts or above is ideal).
- Clean Battery Terminals: Remove any corrosion with a wire brush and apply dielectric grease to prevent future corrosion.
- Secure Connections: Ensure all battery connections are tight and secure. Loose connections can lead to intermittent power issues.
Speed Sensor Inspection
- Locate the Speed Sensor: Refer to your bike’s manual to find the speed sensor’s location.
- Clean the Sensor: Remove any dirt, grime, or debris that could interfere with the sensor’s operation. A clean sensor can often resolve the P1632 code.
- Check for Damage: Inspect the sensor for any signs of damage or wear. Replace if necessary.
Ignition Switch Check
- Recall Information: Verify if your model has a recall on the ignition switch and if it applies to your bike.
- Inspect for Wear: Check the ignition switch for any signs of damage or unusual wear. Issues with the ignition switch can lead to electrical problems, including the P1632 code.
Voltage and Grounding Tests
- Test the Charging System: Use a multimeter to ensure the charging system is functioning correctly. The voltage should increase slightly when the engine is running.
- Ground Connection Check: Ensure the main ground connection from the battery to the frame and engine is clean, secure, and free of corrosion.

Should You Be Concerned?

While the P1632 code itself does not pose a direct threat to the motorcycle’s performance, it can lead to a series of inconveniences for the rider. The speedometer might drop to zero randomly, indicator lights may malfunction, or the motorcycle may show signs of loss of power. Therefore, it’s essential to address this issue as soon as possible to ensure a smooth and safe riding experience.

What Does The Community Say?

Many riders have encountered the P1632 code, and the general consensus within the community is that battery-related issues are often the root cause. Many Harley owners have reported that the code cleared after they replaced the battery, cleaned battery connections, or addressed other battery-related issues.

Example #1

John, a Harley Davidson enthusiast, encountered the P1632 code on his 2016 Dyna Street Bob after a long ride. Initially, he noticed his motorcycle sputtering and the speedometer dropping to zero at random intervals. Suspecting a battery issue, John checked the battery connections, which appeared secure. However, upon closer inspection, he discovered that the battery terminals were slightly corroded. After cleaning the terminals and securing the connections, the P1632 code persisted. John then replaced the battery, and to his relief, the issue was resolved. This example underscores the importance of not only checking the connections but also assessing the battery’s health and terminals’ condition.

Example #2

Emily experienced intermittent power loss and the P1632 code on her 2017 Street Bob. After researching and consulting with fellow riders on forums, she decided to inspect the speed sensor for dirt and debris, a common suggestion from the community. Upon inspection, she found the sensor covered in grime, which she carefully cleaned. Additionally, Emily learned about a recall on ignition switches for certain models and, although her bike wasn’t part of the recall, decided to inspect the ignition switch for any signs of wear or damage. After cleaning the speed sensor and confirming the ignition switch was in good condition, her bike’s performance improved significantly, highlighting the potential impact of these components on the P1632 code.

Are Any Repairs Necessary To Fix The Code?

If your Harley is displaying the P1632 code, there are a few rectification methods you can attempt before taking your bike to a mechanic. Start by checking the battery and its connections. If you recently replaced the battery or the cables, the issue might persist if the connections are not properly secured.

How Can You Clear The Code?

To clear the P1632 code, start by addressing the potential causes. This could involve replacing the battery, cleaning or tightening the connections, replacing the speed sensor, or servicing the ignition switch. After performing these rectifications, you should clear the code using a compatible diagnostic tool.
