How do I recalibrate the tire pressure monitoring system on my Ford Focus?

My tire pressure monitoring system on my Ford Focus seems to be giving inaccurate readings. I've checked the tire pressure and everything seems fine. Is there a way to recalibrate the system?

First, try resetting the TPMS by holding down the reset button for 3 seconds. If that doesn't work, you may need to take your car to a mechanic for further diagnosis and potential recalibration.

Make sure all of your tires are properly inflated. Sometimes even a small difference in pressure can trigger the TPMS. If that doesn't work, you may need to replace the sensors.

Check the spare tire as well, as it can also trigger the TPMS. If you still have issues, it may be a faulty sensor or wiring problem.
