Speed Sensor Troubleshooting
Follow the steps listed below to locate and correct sensor-
related ABS diagnostic trouble codes.
1. Access active diagnostic trouble code(s) using the blink
code procedure, the hand-held tester or ServiceRanger
software.
2. Look up the code description, the possible causes and
the repair procedures provided in this section.
3. Perform the recommended repair procedures.
4. After the repairs are completed, clear all codes and
check for any additional codes.
Note: Drive the vehicle. The indicator lamp will remain
on until proper sensor output is detected, even though the
diagnostic trouble code has been cleared.
Speed Sensor Resisitance Test
The correct resistance for the
speed sensor circuit is between
1500 ohms and 2500 Ohms.
Measure resistance at the wheel
location to check the speed sensor.
Measure resistance at the
appropriate ECU harness
connector pins to check the cable
and speed sensor.
Note: Refer to the chart for pin
identification.
