Check to make sure transmission range sensor harness connector is fully seated, terminals are fully engaged in connector and in good condition
before proceeding.
-
Verify shift linkage adjustment in the Overdrive position.
-
Turn ignition switch OFF.
-
Apply parking brake control.
-
Place transaxle in Neutral.
-
Verify that Transmission Range/Manual Lever Position Sensor Alignment Tool T92P-70010-AH fits in the appropriate slots.
Is the transmission range sensor properly adjusted?
Yes
REMOVE tool.
GO to A2.
No
ADJUST transmission range sensor. See: Adjustments
After adjustments, PLACE shift control selector lever in Park.

-
Place VOM on 20 volt scale.
-
Turn ignition switch to RUN, engine OFF.
Is voltage between 4.75 and 5.25 volts?
Yes
GO to A3.
No
REFER to Computers and Controls/System Diagnosis for diagnosis of NO Reference Voltage, Pinpoint Test TD.
A3 Check Continuity Of TR Sensor Harness Circuits
-
Turn ignition switch to OFF.
CAUTION: Do not pry connector. Press button and pull up on vehicle harness.
-
Disconnect transmission range sensor.
-
Inspect for damaged or pushed-out pins, corrosion, or loose wires.
-
