Decoding Honda Transmission Codes

Honda transmission codes are alphanumeric identifiers that indicate specific problems within the transmission system. These codes are typically retrieved using an OBD-II scanner, which connects to your vehicle’s diagnostic port. Understanding what these codes mean is crucial for accurate diagnosis and repair.

Common Honda Transmission Codes and Their Meanings

• P0700: Transmission Control System Malfunction ⸺ This is a general code indicating a problem within the transmission control system. It often requires further investigation to pinpoint the exact issue;
• P0715: Input/Turbine Speed Sensor Circuit Malfunction ⸺ This code suggests a problem with the input speed sensor, which monitors the speed of the transmission’s input shaft.
• P0717: Input/Turbine Speed Sensor Circuit No Signal ⸺ Similar to P0715, but indicates a complete loss of signal from the input speed sensor.
• P0720: Output Speed Sensor Circuit Malfunction ⸺ This code points to a problem with the output speed sensor, which monitors the speed of the transmission’s output shaft.
• P0730: Incorrect Gear Ratio ⸺ This code indicates that the transmission is not shifting into the correct gear for the vehicle’s speed and engine load.

Troubleshooting Honda Transmission Issues

Once you’ve retrieved a transmission code, the next step is to troubleshoot the problem. Here’s a general approach:

1. Verify the Code: Double-check the code using a reliable source to ensure accurate interpretation.
2. Inspect Wiring and Connections: Look for any damaged, corroded, or loose wiring and connectors related to the affected sensor or component.
3. Test the Sensor/Component: Use a multimeter to test the sensor or component’s resistance and voltage, comparing the readings to the manufacturer’s specifications.
4. Check Transmission Fluid: Ensure the transmission fluid is at the correct level and in good condition. Low or contaminated fluid can cause various transmission problems.
5. Consult a Professional: If you’re unsure about any step of the troubleshooting process, consult a qualified mechanic.

Remember, proper diagnosis is key to avoiding unnecessary repairs. Don’t simply replace parts based on a code alone. Take the time to thoroughly investigate the issue.
