• parking aid module (located behind the LH C-pillar trim panel)
• parking aid speaker-audible warning tone (located on the parking aid module)
• reverse gear select input (to the parking aid module from the reverse lamp circuit)
• The parking aid system is enabled when the ignition switch is in the RUN position and REVERSE is selected. The system can be disabled through the message center RESET switch located in the instrument cluster. The parking aid menu is displayed until the transmission is taken out of REVERSE. While the menu is displayed, pressing the message center RESET switch changes the parking aid system status to OFF.

if I remember its .054" gap. there should be a decal under the hood somewhere that has the gap on it.

On the transmission is a sensor ,Transmisson range sensor.This sensor tells the ( PCM ) engine computer what gear the vehicle is in.The PCM in turn puts a message on the serial data bus ,where the instrument cluster reads it and puts it on PRND321 what ever gear your in. That part of your cluster mite be bad or the range sensor mite need to be adjusted . There mite be a DTC stored in one of the modules . Serial Data Bus you should read this if don't know what this is.

tun the fault codes to determine the possible fault sensor
indicates a crank/cam position sensor

You may want to check the throttle position sensor and map sensor
