DIAGNOSTIC TROUBLE CODE (DTC) 03
LEFT FRONT WHEEL SPEED SENSOR FAULT
KAA4F140
Circuit Description
The toothed wheel generates a voltage pulse as it
moves past the sensor. Each tooth-gap-tooth series
on the wheel generates the pulses. The electronic brake
control module (EBCM) uses the frequency of these
pulses to determine the wheel speed. The voltage gen-
erated depends on the air gap between the sensor and
the toothed wheel, and on the wheel speed.
Diagnosis
This procedure checks for a malfunctioning wheel speed
sensor, a short to ground or to voltage in the wiring, or
a contact problem in a connector.
Cause(s)
The wheel speed sensor is defective.
There is a problem in the wiring.
There is a problem with a connector.
Fail Action
ABS action is disabled, and the ABS warning lamp is
ON.
Test Description
The number(s) below refer to step(s) on the diagnostic
table.1. This step begins an examination for a defective
wheel speed sensor.
6. This step tests the wiring for a short to voltage.
8. This step tests the wiring for a short to ground.
10. This step tests for an open or a high resistance in
the wiring.
Diagnostic Aids
Be sure that the speed sensor wiring is properly routed
and retained. This will help to prevent false signals due
to the pickup of electrical noise.
It is very important to perform a thorough inspection of
the wiring and the connectors. Failure to inspect the
wiring and the connectors carefully and completely may
result in misdiagnosis, causing part replacement with
the reappearance of the malfunction.
Use the scan tool to monitor wheel speeds during a
road test. Watch the wheel speeds being displayed on
the scan tool to see if any of the readings are unusual,
such as one sensor varying in speed from the other
three, a signal going intermittently high or low, etc. If
this does not identify the intermittent, wet the speed
sensor harness on the underside of the vehicle and
perform a road test, monitoring wheel speeds with the
scan tool.

1. Turn the ignition to LOCK.
2. Disconnect the left rear wheel speed sensor
connector.
3. Use a digital voltmeter (DVM) to measure resis-
tance between the sensor terminals.

mately 25-C (77-F)?
Replace the wheel speed sensor.
Is the repair complete?
1. Switch the DVM to the ac millivolt range.
2. Measure the voltage output between the wheel
speed sensor terminals while rotating the wheel
about 1 revolution per second.
Is the output within the specified value?
Replace the speed sensor or the toothed wheel, as
required.
Is the repair complete?
1. Disconnect the harness from the EBCM.
2. Connect a DVM between ground and one terminal of
