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 vehicle’s overall performance.

Check Recommended Air Levels: 

1. Refer to the Manufacturer’s Sticker located on the inside of the Driver’s door. 
2. Make sure the spare has the correct amount of air as well.
3. Keep a tire pressure gauge close by to check your tires just in case the warning light comes on again.

Reset the Warning Light:

1. Set your Brake (Optional but Safe). 
2. Fill each tire to the recommended PSI/Air Pressure Levels, including the spare. 
3. Drive your vehicle at 15/mph for twenty minutes.
4. The TPMS warning light on your Chrysler Pacifica should be cleared.

FAQS

When will the light turn off?

After the tires are inflated/deflated, the outdoor temperature affects how fast the air in the tires will adjust to the proper temperature. Be patient and give the tires time to adjust.

What if the light doesn’t turn off?

If the tire pressure warning light stays illuminated past a week, take it to a repair shop. They may reprogram the system with a professional tool. If reprogramming fails, there could possibly be a sensor issue or a tire puncture.
