WARNING: This page is about a different variant/trim than selected.
The purpose of the diagnostic is to monitor the rationality of the park pawl sensor signal. The sensor has two pins to determine the position of the park pawl as shown in the table below.
| PIN 1 = 0 | PIN 2 = 0 | Undefined Output |
| PIN 1 = 1 | PIN 2 = 0 | Park Pawl Engaged |
| PIN 1 = 0 | PIN 2 = 1 | Park Pawl Disengaged |
| PIN 1 = 1 | PIN 2 = 1 | Intermediate Position |
This diagnostic monitors for two types of faults:
- Undefined output of the sensor
- Sensor too long in intermediate position
If the output of the sensor is undefined or the sensor is in the intermediate position too long, this Diagnostic Trouble Code (DTC) will set.
NOTE:
A binding or obstructed Manual Park Release (MPR) can cause tis DTC to set.
