The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in modern vehicles, including the 2006 Honda Ridgeline. It continuously monitors tire pressure and alerts you to any significant drops, ensuring optimal safety and fuel efficiency. Understanding how this system works and knowing where to find your OBD2 port are essential for maintaining your vehicle. This guide will walk you through the TPMS of your 2006 Honda Ridgeline, including how to reset it and where to locate the OBD2 port for diagnostics.
Understanding the TPMS in Your 2006 Honda Ridgeline
Your 2006 Honda Ridgeline is equipped with a sophisticated TPMS that keeps a watchful eye on all four tires whenever the engine is running. This system is designed to detect when a tire’s pressure falls below 24 psi (168 kPa). If this occurs, the system promptly alerts you by activating the low pressure indicator, illuminating the corresponding tire indicator on your multi-information display, and storing a diagnostic trouble code (DTC) in the control unit.
Once the tire pressure is corrected and exceeds 29 psi (198 kPa), the TPMS control unit automatically turns off the warning indicators and stores any set DTCs. In situations where two or more tires are low on pressure, the low pressure indicator will illuminate briefly before the individual tire indicators, ensuring you are fully informed of the issue. The system is also intelligent enough to scan all four sensors to pinpoint the exact tire(s) with low pressure.
If the TPMS detects a system malfunction, the TPMS indicator will light up. In cases where both low tire pressure and a system problem are present, only the TPMS indicator will be activated. When a system issue is detected, the TPMS control unit will record a DTC and enter a fail-safe mode, which means it will not alert you to low tire pressures until the system issue is resolved. If the TPMS control unit loses power or fails, the TPMS indicator will illuminate, but no DTC will be stored.
Each tire pressure sensor is a self-contained unit integrating the tire valve stem, a pressure sensor, and a transmitter. This unit is securely attached to the inside of the wheel around the valve stem. To prevent signal interference from other vehicles, each sensor has a unique ID.
After the TPMS control unit learns and memorizes all sensor IDs, it exclusively responds to signals from these specific sensors. This ID memorization can occur automatically or manually. Initiators located in each wheel housing are wired to the control unit. Each time you turn the ignition to the ON position, the control unit requests sensor IDs from each initiator. The initiators then transmit these IDs, which the control unit receives and memorizes. This process allows the system to accurately identify each sensor’s location, even after tire rotations. This recurring ID confirmation ensures the system remains accurate and avoids confusion due to routine tire maintenance.
Locating the OBD2 Port on Your 2006 Honda Ridgeline
For diagnostics and resetting procedures, accessing the OBD2 port is essential. On your 2006 Honda Ridgeline, the OBD2 location is conveniently situated under the dashboard on the driver’s side. Specifically, you’ll find it to the left of the steering column. You may need to look under the dash, near the area where your knees would be while driving. It’s typically not hidden behind a panel but is openly accessible for easy connection to a scan tool.

This standard 16-pin Data Link Connector (DLC) allows you to connect an OBD-II compatible scan tool or the Honda Diagnostic System (HDS) to read diagnostic trouble codes, monitor system parameters, and perform resets, including TPMS sensor ID memorization.
TPMS Warning Indicators Explained
Understanding the TPMS warning indicators is crucial for interpreting your 2006 Honda Ridgeline’s alerts. There are a few key indicators to be aware of:
- Low Tire Pressure Indicator (Tire Symbol): This light, often resembling a horseshoe shape with an exclamation point or a deflated tire icon, illuminates when one or more of your tires are significantly underinflated. Along with this, the specific tire(s) with low pressure will be indicated on the multi-information display.
- TPMS Indicator (TPMS Symbol): This indicator, often displaying the letters “TPMS,” lights up when the system detects a malfunction within the TPMS itself. This could be due to a sensor failure, control unit issue, or other system problems. If this light is on, the system may not be actively monitoring tire pressures.
It’s important to note that tire pressures naturally fluctuate with temperature changes. A temperature change of about 50 degrees Fahrenheit (10 degrees Celsius) can alter tire pressure by approximately 1.5 psi (10 kPa). This means that during colder weather, tire pressure may drop enough to trigger the low pressure indicator. Conversely, as temperatures rise, the light may turn off. If you experience intermittent warnings, especially with temperature changes, it’s advisable to manually check your tire pressures and adjust them as needed.
Note: If the ambient temperature drops to -40 degrees F (-40 degrees C) or below, the TPMS may not function reliably.
If the low tire pressure indicator and multi-information display indicators remain continuously lit due to low pressure, inflate your tires to the recommended pressure specified on the tire and loading information placard, usually located on the driver’s side doorjamb. The indicator light should turn off shortly after driving once the correct pressure is reached. If the warning lights persist, it indicates a problem within the TPMS requiring further diagnosis.
Resetting the TPMS System on Your 2006 Honda Ridgeline
Resetting the TPMS on your 2006 Honda Ridgeline is necessary when you rotate your tires or replace a tire pressure sensor. There are two primary methods for resetting the system and memorizing sensor IDs: automatic memorization and using the Honda Diagnostic System (HDS) or an OBD-II compatible scan tool.
Memorizing Sensor ID (Automatically)
This method is straightforward and typically used after tire rotation or sensor replacement.
- Drive: After rotating your tires or installing a new TPMS sensor, drive your 2006 Honda Ridgeline for at least 40 seconds at a speed of 15 mph (24 km/h) or greater. The system will automatically begin to memorize the sensor IDs.
- Confirmation: To verify successful memorization, reduce the tire pressure in all four tires below the recommended specification. Check that the four tire indicators illuminate on your dashboard. This confirms that the system is reading pressure from all sensors.
Memorizing Sensor ID (Using HDS or OBD-II Scan Tool)
If automatic memorization is unsuccessful or if you have replaced the TPMS control unit, you’ll need to use the Honda Diagnostic System (HDS) or an OBD-II compatible scan tool. This method requires accessing the OBD2 location on your 2006 Honda Ridgeline.
- Connect Scan Tool: With the ignition switched OFF, locate the OBD2 port under the dashboard on the driver’s side of your 2006 Honda Ridgeline. Connect your HDS or OBD-II scan tool to this port.
- Initiate Learning: Turn the ignition switch to the ON position (do not start the engine). Follow the prompts on your HDS or scan tool to initiate the TPMS sensor ID memorization process.
- Follow Screen Prompts: The scan tool will guide you through the steps to memorize the sensor IDs. If all IDs are successfully memorized, proceed to step 5. If the system fails to learn one or more IDs, continue to the next step.
- Troubleshooting (If Necessary): If sensor ID learning fails, clear any DTCs using the HDS or scan tool. With assistance, start the learning process again while driving the vehicle at a speed under 10 mph. This slower speed learning process can sometimes resolve issues with sensor ID acquisition. If problems persist, consult the service information for your 2006 Honda Ridgeline or seek professional assistance.
- Confirmation: After successful ID memorization, reduce the pressure in all four tires below the recommended level to ensure all tire indicators illuminate, confirming the system is functioning correctly.
