The Park Neutral Position switch or its wiring circuit is bad resulting in the P indicator light not working.
When this circuit is bad, the interlock system would not work correctly and you would not be able to remove the ignition key as it is not being informed by the PNP that gear shift is in park.
Try readjusting the PNP and retest. It could also be due to a faulty wiring circuit of the Park circuit.
