DRIVETRAIN SYSTEM
GEAR POSITION SWITCH
INSPECTION
Turn the ignition switch OFF.
Disconnect the PCM 33P (Black) connector (page 21-
6).
Check for continuity between each gear position
switch wire terminal of the PCM connector and
ground.
There should be continuity only at the terminals that
correspond to the gearshift lever positions shown
below, and there should be no continuity at the
other terminals.
You must test each of the three wires in each gear-
shift lever position. Therefore, you need to make 9
tests, between each gear position switch wire termi-
nal and ground.
If the test result is abnormal, disconnect the gear
position switch 3P (Natural) connector.
Perform the continuity test at the 3P (Natural) con-
nector in the same manner (page 14-44).
If the test result at the PCM is abnormal and the
one at the 3P connector is normal, check for open
or short circuit, or loose or poor connector con-
tact.
If the both test results are abnormal, replace the
gear position switch.
