Do you mean
1) the shifter does not show it at "P"?
or
2) the transmission will not go to Park?
If 1, then the indicator is broken. You just have to go by "feel". Mine just broke a few months ago but I don't want to deal with remove the stalk and then reparing it. Most of the time, I don't look at the shift lever anyway.
If 2, then you may want to check if the Manual Lever Position sensor needs readjustment. Maybe the screw got loose ...
or maybe the tranny is on its last legs.
Manual Lever Position Switch/Transmission Range Sensor
REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4 and 5
The manual lever position sensor (transmission range sensor) is only used on vehicles equipped with an automatic transaxle. It performs several tasks, it acts as the neutral safety switch, the back-up light switch, and also is an input to the PCM of gear position.
- Disconnect the negative battery cable.
- Place the transmission manual control lever in the NEUTRAL position.
- Remove the engines air intake resonators and Mass Air Flow (MAF) sensor.
- Disconnect the electrical harness connector from the manual lever position sensor, which is located on top of the automatic transaxle.

- Remove the 2 retaining bolts and remove the manual lever position sensor.
To install:
- Make sure that the transmission manual control lever is in the NEUTRAL position.
- Reinstall the manual lever position sensor and loosely install the 2 retaining bolts.
- Align the sensor slots using Transmission Range Sensor Tool T94P-70010-AH, or equivalent.

- Torque the retaining bolts to 84-108 inch. lbs. (9-12 Nm).
- Reinstall the electrical harness connector to the sensor.
- Reinstall the MAF sensor and the air intake resonator.
- Reconnect the negative battery cable.
- Engage the parking brake and check for proper operation and adjustment of the manual lever position sensor as follows:
- Check that the engine will only crank in the PARK or NEUTRAL positions.
- Check that the back-up lamps only work in the REVERSE position.
