I'd 1st investigate the connections to the brake pedal switch and the wiring to it for any crimp damage or fraying. Ideally use a multimeter to check that the switch is working OK. This is because the gearbox controller won't allow the lever to shift from park until it sees that your foot is on the brakes

There should be 2 switches one for the brake lights and the other for the gearbox and both are located at the top of the brake pedal in the drivers footwell.

If this is OK then check that the P is illuminated up on the shifter. If any other gear is illuminated up then the usual cause are loose shifter cable bolts. You need to jack up the driver side of your vehicle and follow the shifter cable to where it attaches to the transmission. You should see two 8mm bolts which may be loose or even have fell out. If the P is lite up make sure your brake lights work. If they do then the fault is usually the actuator in the shifter. There is a manual over ride. Pop off the wood grain and move the lever on the driver side on the shifter to release it from park.
