Ignition off
Disconnect the transmission connector
Connect an ohmmeter between terminals #6 and #7 on the transmission connector (transmission side)
Ignition key in the radio position (I).
Press the "Shift-lock Override" button. Move the gear selector to all gear positions. Check the resistance.

The resistance should be approximately 0 Ω in positions P and N and infinite in all other positions.

Replace the gear-shift position sensor if the resistance is incorrect.

NOTE:
With the ignition on and the transmission disconnected, the transmission control module (TCM) may store diagnostic trouble codes (DTCs). If the ignition has been on, erase any stored DTCs.

Was the resistance OK?

YES
Refer to Checking the wiring
NO
