abs sensors harness may be damaged giving both sensors as problem or hub failure will need to test abs system as to cruise if problems with abs / trans / speed sensors etc cruise will not work built in safety but as to abs or speed sensor problems go they dont cause stalling when stopping

Where is the speed sensor located . please be very specific.gauge in the speedometer works when it feels like it. i wonder if it's the speed sensor...


Is your ABS light on? This is usually a fault of the ABS control unit located under the brake proportioning valve. Speed sensors are located on the back side of each brake disc That info is sent to the ABS control unit then to the main computer. Is your ABS light on? This problem could be caused by bad sensors or more likely the ABS control unit.

Abs speed control flashing


Likely an ABS Wheel Speed Sensor is not sending the proper signal to the ABS module.
Could be a dirty sensor, ring, or a bad wiring to the sensor from the ABS control module.

Check for a dirty sensor, first.

Whats wrong my abs light is on, my brake light is on and my speedometer nor odometer are working? 2004 jeep grand cherokee larado 6 cyl 4.0 liter


here is the short version...

the vehicle speed sensor is actual an interpreted signal from the ABS module and the ABS module uses the wheel speed sensors

therefore, if the ABS module sees a problem with any sensor it will affect the PCM input for vehicle speed

another possibility, but worst case, is the ABS module has failed

in either case you will need a professional scan tool to monitor actual wheel speed versus PCM vehicle speed

Abs comes on when turning at slow speeds when parking 2003 sierra


most likely you have a wheel sensor going out. The only way to tell which one is with a data scanner that can access the ABS system.

It will see all the tires spinning at the same speed until one shows a different speed.

Also make sure you have all the same tires and the air pressures are the same.

ABS brake module sounds like a motor running and won't stop unless battery is disconnected. what is fix?


I would pull the fuse for the ABS hydraulic pump and then put it back in and see what happens. Don't ever recall a pump running. Dealer may need to hook up scan tool for diagnostic fault codes, DTCs.



Principles of Operation
The ABS control module receives wheel speed readings from both front wheel speed sensors and the rear differential speed sensor, and processes this information to determine if an ABS event is necessary. The wheel speed sensor electrically senses each tooth of the ABS sensor indicators as it passes through the wheel speed sensor's magnetic field.
The ABS control module continuously monitors and compares the rotational speed of each wheel speed sensor indicator and, when it detects an impending wheel lock, modulates brake pressure to the appropriate brake caliper(s). This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS control module returns the solenoid valves to their normal position, and normal (base) braking resumes.
The ABS control module is self-monitoring. When the ignition switch is turned to the RUN position, the ABS control module will do a preliminary electrical check, and at approximately 20 km/h (12 mph), the pump motor is turned on for approximately one-half second. Any malfunction of the ABS system will cause the ABS to shut off; normal power assisted braking, however, remains.
Inspection and Verification — Scan Tool Communications Check
  1. Verify the customer concern by carrying out the Drive Cycle Test.
  1. Visually inspect for obvious signs of mechanical and electrical damage.
