What Does Tire Pressure Warning Light / TPMS Mean?

Reviewed by automotive technicians · Last updated August 22, 2026

Quick Answer

Tire Pressure Warning Light / TPMS = One or more tires on the Toyota 4Runner has pressure below the recommended cold inflation pressure (typically 32-35 PSI on 4Runner models). A SOLID TPMS light means low tire pressure. A FLASHING TPMS light (60-90 seconds on startup then solid) means a system fault — a dead sensor or communication loss. The 4Runner uses direct TPMS sensors in each wheel valve stem.

DRIVE WITH CAUTION — Repair Soon

One or more tires on the Toyota 4Runner has pressure below the recommended cold inflation pressure (typically 32-35 PSI on 4Runner models). A SOLID TPMS light means low tire pressure. A FLASHING TPMS light (60-90 seconds on startup then solid) means a system fault — a dead sensor or communication loss. The 4Runner uses direct TPMS sensors in each wheel valve stem.

What to Do Right Now

Check all four tire pressures (including the spare tire on 5th-gen 4Runner — the full-size spare under the cargo area has a TPMS sensor too) with a gauge as soon as possible. The recommended pressure is on the driver's door jamb sticker. Inflate any tire below 30 PSI immediately. After inflating, drive above 30 mph for at least 10 minutes — the TPMS system will auto-relearn the new pressures. If the light persists after correct inflation, the TPMS sensor battery may have died (typical lifespan is 7-10 years).

Frequently Asked Questions

Can I drive my Toyota 4Runner with the Tire Pressure Warning Light on?

Yes, but check tire pressures immediately — driving on severely underinflated tires on a heavy SUV like the 4Runner increases blowout risk significantly. Inflate to the door jamb sticker pressure as soon as possible.

How much does it cost to fix the Tire Pressure Warning Light on a Toyota 4Runner?

DIY cost: $0-5 (air at a gas station). Mechanic estimate: $60-120 per TPMS sensor replacement if a sensor battery has died; $50-100 for TPMS reset procedure. The 4Runner's full-size spare tire also has a TPMS sensor — don't forget to check it.

What causes the Tire Pressure Warning Light to come on in a Toyota 4Runner?

Common causes: seasonal temperature drops (every 10°F drop loses about 1 PSI), slow leak from nail or screw in off-road driving, TPMS sensor battery failure after 7-10 years, or the spare tire under the cargo area having low pressure. The 4Runner's tire pressure spec is higher than sedans — typically 32-35 PSI — because of the vehicle's weight.
