What Does TPMS Warning Light / Tire Pressure Monitoring Mean?

Reviewed by automotive technicians · Last updated August 22, 2026

Quick Answer

TPMS Warning Light / Tire Pressure Monitoring = The Tire Pressure Monitoring System has detected that one or more tires are below the recommended cold inflation pressure (typically 32-35 PSI on Honda Accord). A SOLID light means low tire pressure. A FLASHING light (60-90 seconds on startup then solid) means a system fault — a dead sensor battery or communication loss. The 2018-2022 Accord uses direct TPMS sensors in each wheel; 2023+ models use an indirect system based on wheel speed sensors.

What to Do Right Now

Check all four tire pressures with a gauge as soon as possible. The recommended pressure is on the driver's door jamb sticker. Inflate any tire below 28 PSI immediately. On 2018-2022 models, after inflating, drive above 30 mph for at least 10 minutes to allow the system to recalibrate. On 2023+ models with indirect TPMS, perform a TPMS recalibration from the vehicle Settings menu on the infotainment screen after adjusting tire pressures.

Frequently Asked Questions

Can I drive my Honda Accord with the TPMS light on?

Yes, but check tire pressures immediately — driving on severely underinflated tires increases blowout risk and reduces fuel economy. Inflate to the door jamb sticker pressure as soon as possible.

How much does it cost to fix the TPMS light on a Honda Accord?

DIY cost: $0-5 (air at a gas station); $20-40 (12V portable air compressor). Mechanic estimate: $60-120 per TPMS sensor replacement if a sensor battery has died; $50-100 for TPMS recalibration procedure. The 2018-2022 Accord uses direct TPMS sensors with 5-7 year battery life.

What causes the TPMS light to come on in a Honda Accord?

A solid TPMS light means one or more tires is below the recommended cold inflation pressure. Common causes include seasonal temperature drops (every 10°F drop loses about 1 PSI), slow leak from nail or screw, or TPMS sensor battery failure after 7-10 years. A flashing TPMS light indicates a system fault — the sensor is not communicating with the vehicle.
