Dr$.$ Ker currently drives a $2007$ Kia Rondo which has run over $220,000$ miles. See the picture below taken in $2020$ as proof.

However, lately Dr$.$ Ker has noticed the Tire Pressure Measurement System $($TPMS$)$ warning light on the dashboard is always on$,$ even if all tires were inflated to above $32$ psi before the trip. As a result, Dr$.$ Ker can no longer rely on this TPMS to monitor his tire pressures. The current tire pressure inspection process used by Dr$.$ Ker is $$visually estimating tire pressure about once every month.$$ That is$,$ when a tire looks flat, Dr$.$ Ker would manually $($meaning using his hand$)$ press the surface of that tire to judge if it needs to be inflated. However, once every three months Ker would bring his car to Walmart to have an oil change service which includes a tire pressure check and a TPMS check.

Assume that the pressure of tires on this car would likely to fall below the required level in three months after each regular maintenance, and Dr$.$ Ker will take his car to Walmart to have an oil change service $($including fixing the TPMS and checking pressure on all tires$)$ every six months. Perform a PFMEA analysis of the tire pressure inspection process used by Dr$.$ Ker. Note that the TPMS will be fixed, and the tires will be inflated to above $32$psi after each service.
