wheel speed sensor

[skizimus]

CHECK FOR SHORTED WHEEL SPEED SENSOR CIRCUITS
• Measure the resistance between the suspect wheel speed
sensor pins.
• Is the resistance greater 10,000 ohms?
Yes
GO to E5.
No
REPAIR the circuit in question. CLEAR the
DTC. REPEAT the self-test.

E5 CHECK THE ABS MODULE OUTPUT
• Connect: ABS Module C135.
• Key in ON position.
• Measure the voltage between the suspect wheel speed sensor
pins, harness side.
• Is the voltage less than 9 volts?

Yes
INSTALL a new ABS module. REFER to
Anti-Lock Brake System (ABS) Module in
this section. CLEAR the DTC. REPEAT
the self-test.

No
INSTALL a new wheel speed sensor. For
the front wheel speed sensor, REFER to
Front Wheel Speed Sensor and Sensor
Ring in this section. CLEAR the DTC.
REPEAT the self-test. For the rear wheel
speed sensor, REFER to Rear Wheel
Speed Sensor and Sensor Ring in this
section. CLEAR the DTC. REPEAT the self-test.

Thank you, but those tests still will not detect problems with the tooth ring (maybe a tooth has fell off) or with the spacing between the ring and the pickup. An oscilloscope will pick those things up (if you know what you are looking for.) Yes, most of the time you don't have to go that far, but sometimes you do.

so i replaced the WSS measured the bad one and it was all over the place checked the new one before I put it in,, it was a stable value, dont remember what it was, but it wasnt anything around what were in those procedures I found, Like 50 ohms or something WT heck. but it was stable. put it in and it works.
