The TPMS (Tire Pressure Monitoring System) sensor is a battery-powered device inside each wheel that measures tire pressure and transmits it to your dashboard. When a sensor fails, the TPMS warning light stays on even with properly inflated tires. Replacement is straightforward but carries a few cost factors worth knowing.
TPMS sensor replacement cost
Aftermarket sensor: $15–35 per sensor for a quality replacement (Dorman, Schrader, Pacific). Labor to install: $30–50 per sensor (requires dismounting the tire to access the valve stem hole).
OEM sensor: $50–100 from the dealer, plus labor. OEM sensors are identical to factory and require no additional programming in most cases.
Programming: most TPMS sensors require programming/relearn after installation. This adds $20–50 at shops that charge separately for the relearn procedure. Many shops include this in the install labor.
Total cost per sensor: $50–150 depending on sensor choice and shop type. A full set of four sensors: $200–400 installed.
When TPMS sensors actually need replacement
Dead battery: TPMS sensors contain a non-replaceable battery with a typical lifespan of 5–10 years. When the battery dies, the sensor stops transmitting and the TPMS light illuminates. This is the most common replacement reason.
Physical damage: a hard pothole or curb strike can crack the sensor body or break the antenna. The sensor stops functioning and must be replaced.
Corrosion: in areas with road salt or high humidity, the aluminum valve stem on metal TPMS sensors corrodes, causing leaks. The corroded sensor must be replaced.
New wheels: when installing aftermarket wheels, new TPMS sensors must typically be installed (or the factory sensors transferred if compatible — ask the shop).
TPMS light vs. sensor failure
The TPMS light can illuminate for two reasons: (1) actual low tire pressure, or (2) sensor malfunction.
Check tire pressure first: if all four tires are at the door jamb specification and the TPMS light stays on, the issue is likely sensor-related.
Some vehicles show a separate blinking TPMS light for sensor failure vs. a solid light for low pressure — consult your owner's manual.
TPMS relearn: after any tire rotation or sensor replacement, many vehicles require a relearn procedure to reassign which sensor is which wheel. This is usually done with a scan tool at the shop — not a DIY procedure on most vehicles.
Frequently asked
Can I drive with a broken TPMS sensor?
Legally: yes in most states after a grace period. Safely: yes, if you manually check tire pressure regularly. The TPMS warning light will stay on, but the tire itself is not affected. The risk is losing the early warning system for genuine pressure loss — if the sensor that would warn you about a slow leak is broken, you might not notice until the tire is dangerously low.
Do I need to replace all four TPMS sensors at once?
No — replace only the failed sensor(s). However, if one sensor's battery has died after 8+ years, the others are similarly aged and may fail soon. Many owners replace all four at once when the first one fails to avoid multiple shop visits within a year.
Are TPMS sensors required by law?
TPMS has been required on all new passenger vehicles sold in the US since 2008 (TREAD Act compliance). It is illegal to disable or permanently remove TPMS. Shops are required to maintain the TPMS system during tire service.
