Chrysler Pacifica: Reset TPMS

If the Tire Pressure Management System in the Chrysler Pacifica is not working properly, you may have to reset the system. Follow the steps below to re-initialize the TPMS.

The warning light indicator is a notification to warn you of significantly low air pressure or high-pressure loss in your tires. Do not ignore the warning, as low pressure affects the vehicles overall performance.

First, Check the Recommended Air Levels Needed

  • Refer to the Manufacturer’s Sticker located on the inside of the Driver’s door. 
  • Make sure the spare has the correct amount of air as well.

FACT! Always keep a tire pressure gauge close by to check your tires just in case the warning light comes on again. 

NOTE: If you are unable to Reset the Tire Pressure Warning Light on the first try, REPEAT the steps. If you are still unsuccessful, contact the dealership for assistance or consult your vehicle user’s manual.


To Reset the Warning Light Perform the following steps:

  1. Set your Brake (Optional but Safe). 
  2. Fill each tire to the recommended PSI/Air Pressure Levels, including the spare. 
  3. Within city limits drive at 15/mph or 24/km for Twenty minutes. Faster on the highway is fine.

TIP: The TPMS warning light on your Chrysler Pacifica should be cleared. However, if the light remains illuminated, keep in mind after tires are inflated/deflated, the outdoor temperature affects how fast the air in the tires will adjust to the proper temperature, this could take a day, 2 or 3, simply be patient and give the tires time to adjust. In addition, if the tire pressure warning light stays illuminated past a week, take it to a repair shop as they may reprogram the system with a professional tool, without a fee. If reprogramming fails, there could possibly be a sensor issue or a tire puncture.
