Introduction

This tutorial provides a straightforward guide to resolving the electric shift problems commonly experienced with the Honda Foreman 500 ES, specifically addressing the issue indicated by the neutral light blinking 13 times. This blinking code signals a problem with the throttle position sensor. By following these steps, you can troubleshoot and fix the issue effectively.

Step 1: Diagnose the Problem

• Check the Blinking Code: If the neutral light blinks 13 times, this indicates a malfunction related to the throttle position sensor.
• Confirm the Symptoms: Ensure that the shifting issue occurs consistently when trying to engage gears.

Step 2: Inspect the Throttle Position Sensor

• Locate the Throttle Position Sensor: The sensor is typically found near the carburetor.
• Check Connections: Make sure all electrical connections to the throttle position sensor are secure and free from corrosion.
• Examine the Sensor: Look for any signs of damage or wear on the sensor itself.

Step 3: Test the Throttle Position Sensor

• Use a Multimeter: Set your multimeter to measure resistance.
• Perform the Test:
  • Disconnect the sensor from the wiring harness.
  • Measure the resistance across the sensor terminals while moving the throttle.
  • The readings should change smoothly. If they are erratic or out of range, the sensor may need replacement.

Step 4: Replace the Throttle Position Sensor

• Purchase a Replacement: Consider options such as:
  • Aftermarket Carb (2005-2011): Link to Aftermarket Carb
  • OEM Honda Carb (2005-2011): Link to OEM Carb
• Install the New Sensor:

• Monitor for Blinking Codes: Check if the neutral light remains steady and does not blink.

Conclusion

By following these steps, you should be able to resolve the electric shift problem on your Honda Foreman 500 ES. Remember to regularly check the throttle position sensor and connections to prevent future issues. If the problem persists after replacing the sensor, consider consulting a professional mechanic for further diagnosis.
