TPMS sensor battery is dead

TPMS sensors have a sealed, non-replaceable battery that typically lasts 5–10 years; once it dies, the whole sensor unit needs replacing.

Difficulty
Moderate
Time
30–60 minutes at a shop
Pro cost
$40–$150 per sensor

Symptoms

  • Persistent TPMS warning that won't clear no matter the pressure
  • One specific tire always shows no reading or an error
  • Sensor is over 5–7 years old

Likely causes

  • CommonSensor battery has reached end of lifeThese batteries are sealed inside the sensor and can't be swapped individually; the whole sensor is replaced.

What to do

  1. Confirm actual tire pressures are correct with a manual gauge to rule out a real pressure issue.
  2. Have a shop scan the TPMS system to identify which sensor, if any, isn't communicating.
  3. Ask about the sensor's age if known, since most fail from battery depletion after 5–10 years rather than damage.
  4. Replace the specific failed sensor rather than the whole set unless multiple are old and likely to fail soon too.
  5. Have the system relearned after sensor replacement so the car recognizes the new unit.

When to call a pro

Replacing a TPMS sensor usually requires removing the tire from the wheel briefly, so this is typically done at a tire shop.
