Speed Sensor Repair Tests:
1. Take all measurements at ECU harness connector
pins in order to check wire harness and sensor.
Probe the connector carefully so that the terminals
are not damaged.
2. Wheel speed sensor measurements should read:
Location Measurement
Sensor 1500 - 2500 Ohms
Sensor to voltage or ground Open Circuit (no continuity)
Sensor output voltage
>0.25 of VAC sensor output at ~ 0.5 revs/sec.
3. Clear DTC after issue is corrected. The sensor DTC
will remain until the power is cycled to the ABS ECU
and vehicle is driven above 15 MPH or DTC was
cleared using either the diagnostic blink code switch
or diagnostic tool.
