Understanding the TPMS in Honda CR-V
The Honda CR-V’s Tire Pressure Monitoring System (TPMS) monitors tire pressure and alerts drivers when pressure drops below a safe level. However, sometimes the TPMS warning light may come on due to factors like temperature changes, sensor malfunctions, or calibration issues.
Common Causes of TPMS Warnings in the Honda CR-V
- Temperature Variations 🌡️
Cold temperatures can lead to a sudden drop in tire pressure, triggering the TPMS warning light. Conversely, higher temperatures can increase pressure temporarily, leading to inaccurate readings. - Aging or Dead Sensor Batteries 🔋
TPMS sensors in the CR-V have a battery life of about 5-10 years. If the vehicle is several years old, a dead sensor battery may cause repeated warnings. - Damaged Sensors During Tire Work
Sensors can sometimes be damaged during tire rotations, replacements, or other tire services, causing the TPMS light to remain on. - Calibration Needs After Tire Service
Whenever tires are rotated, filled, or changed, the system may need to be recalibrated to reflect the new tire conditions accurately.
Steps to Address a TPMS Warning in the Honda CR-V
1. Verify Tire Pressure Manually
- Use a manual gauge to measure each tire’s pressure and compare it to Honda’s recommended level, listed in the driver’s side door jamb.
- Inflate any tires that are low, then drive for a few minutes to see if the TPMS light clears.
2. Resetting the TPMS Light
- The Honda CR-V allows for a manual reset:
- Start the engine and locate the TPMS reset button (often found near the dashboard or in the settings menu of the infotainment system).
- Press and hold the button until the light blinks, then drive for 10–20 minutes to allow the system to recalibrate.
3. Inspect Sensors for Physical Damage
- If the warning persists after resetting, one of the sensors could be damaged. A certified technician can inspect each sensor and determine if a replacement is needed.
4. Software Update for the TPMS Module
Occasionally, TPMS issues can result from outdated software. Ask your Honda dealer if there’s a software update for your model’s TPMS module.
When to Visit a Service Center
If the light remains on after trying these steps, a service center can perform a detailed diagnostic check to identify whether the fault lies with a specific sensor or the TPMS module itself.
