To reset the low tire pressure warning on a 2020 Honda CR-V, inflate all tires to the recommended cold pressures listed on the driver’s door jamb label and perform a TPMS relearn, which can be done by driving at highway speeds or, if equipped, with the TPMS reset button.
The tire-pressure monitoring system uses sensors in each wheel to monitor pressure. When tires are inflated or rotated, the system must relearn the new values. Procedures can vary slightly by trim, so consult the owner’s manual for your exact model if you’re unsure.
Steps to reset the TPMS
Before attempting a reset, make sure all tires are inflated to the recommended cold pressures and determine whether your trim supports a manual TPMS restart or relies on a drive-based relearn.
- Park on a level surface and turn the ignition to ON with the engine off.
- Check all four tires to ensure they’re inflated to the recommended cold pressures printed on the door jamb label, and adjust as needed.
- If your CR-V has a TPMS reset button, locate it (commonly near the left side of the instrument panel) and prepare to use it.
- For models with a reset button: press and hold the TPMS button until the warning light in the instrument cluster blinks or you hear a chime, then release.
- If your vehicle does not have a reset button, proceed with the drive-based relearn: after inflating the tires, drive at speeds above roughly 30–50 mph for about 10 minutes to relearn the tire sensor values.
- Continue driving normally until the TPMS warning light goes out. If it stays illuminated, you may have a slow leak or a faulty sensor.
- After the light goes out, recheck tire pressures to ensure they remain at the recommended values and inspect for leaks or damage.
Note: Exact steps can vary by trim and sensor type. If the light remains after attempting the relearn, seek service from a qualified technician or a Honda dealer.
Troubleshooting and common issues
If the reset procedure doesn’t resolve the warning, consider these factors and actions:
- Slow leaks: A tire may appear properly inflated but lose air over time, keeping the light on.
- Sensor fault: A damaged or aged TPMS sensor can fail to relay readings, requiring replacement or reprogramming.
- Incorrect relearn procedure: Some wheels require a specific order or certain driving conditions to relearn successfully.
- Wheel/tire changes: After rotating or replacing tires, sensors may need proper reprogramming or relearn.
If you suspect any of these issues, a tire or service center can perform a dedicated TPMS reinitialization and check for leaks or sensor faults.
Summary
Resetting the low tire pressure light on a 2020 Honda CR-V involves inflating all tires to the manufacturer-recommended cold pressures and performing a TPMS relearn, either automatically through driving or manually via a reset button if your model supports it. If the light persists after following these steps, seek professional inspection to rule out leaks or sensor problems. Regularly checking tire pressure and keeping tires properly inflated helps ensure safety and optimal fuel economy.
