1. Remove the vehicle speed sensor (VSS). Refer
to Vehicle Speed Sensor (VSS) Replacement in
this section.
2. Visually inspect the VSS for the following
conditions:
•
Physical
damage
•
Being
loose
•
Improper
installation
•
For transmission output shaft teeth damage
3. Repair or replace as necessary.
Did you find and correct the condition?
Go to Step 20

1. Turn OFF the ignition.
2. Disconnect the VSS harness connector.
3. Connect a test lamp between the ignition voltage
feed circuit of the VSS harness (pin 1 of E-44
connector) and a known good ground.
4. Turn ON the ignition, with the engine OFF.
Does the test lamp illuminate?
Go to Step 7
Go to Step 9

1. Turn ON the ignition, with the engine OFF.
2. Connect a test lamp between the ignition voltage
feed circuit and low reference circuit of the VSS
harness (pins 1 and 2 of E-44 connector).
Does the test lamp illuminate?
Go to Step 8
Go to Step 10

1. Turn ON the ignition, with the engine OFF.
2. Intermittently jump the signal circuit of the VSS
(pin 3 of E-44 connector) with a test lamp that is
connected to a known good ground while
monitoring the Vehicle Speed parameter with the
scan tool.
Does the scan tool indicate any vehicle speed when
the circuit is intermittently pulled to ground?
Go to Step 14
Go to Step 11
9
Repair the open or high resistance in the VSS
ignition voltage feed circuit between the Meter (10A)
fuse (C-14) and the VSS (pin 1 of E-44 connector).
Did you complete the repair?
Go to Step 20
10
Repair the open or high resistance in the VSS low
reference circuit between the VSS (pin 2 of E-44
connector) and the chassis ground.
Did you complete the repair?
Go to Step 20
11
1. Turn OFF the ignition.
2. Remove the instrument panel (IP) cluster in order
to disconnect the B-23 harness connector.
3. Disconnect the IP cluster B-23 harness
connector.
4. Turn ON the ignition, with the engine OFF.
5. Intermittently jump the signal output circuit of the
VSS signal (pin 8 of B-23 connector) with a test
lamp that is connected to a known good ground
while monitoring the Vehicle Speed parameter
with the scan tool.
Does the scan tool indicate any vehicle speed when
the circuit is intermittently pulled to ground?
