SOURCE: where is the 4x4 encoder motor sensor located on my 03 sierra

the encoder motor sensor is inside the encoder motor. the encoder is located at the transfer case. Remove the encoder and by part number 88962315 this is the sensor. you will have to retime the motor after
hope this helps

SOURCE: I pulled the codes and here they are : C0036, C0035, C0040

Sounds like you need front wheel speed sensors. Replace the wheel bearings and sensors. May have an ABS unit fault, but more likely is both wheel bearings/speed sensors.

SOURCE: HOW TO REPLACE OR REPAIR WHEEL SPEED SENSOR

It is part of the bearing hub assembly.Very have to do without air tools,If setting multiple abs/tc code (wheel speed sensors) probably abs electronic module or chaffed wires on drivers side at ac lines by air box.Have big problems with this and probably will come back.

Getting abs codes co 222 and co 223 on my 2000 gmc sierra. I changed the right front wheel speed sensor and cleaned where it mounts. cleared the codes and when I start my truck they are coming up again


Check the front hubs, I have seen these where the ring that the abs sensor reads damaged by corrosion which will give a false reading and recurring fault codes.

I have a 2004 yukon xl 1500 all wheel drive with traction control switch and when i stop i get the usual abs slip function . the abs light is on code is right front wheel sensor . replaced now when i pull...


It could be simple, when it starts grabbing and you've driven it for say a mile or 2 have you gotten out and felt the rotor with your finger? If you haven't be very careful, it could be hot enough to blister you. It could simply be that your caliper is now hanging up and the pads are dragging or maybe your wheel hub assembly bearing is finally giving up. I owned a 2002 Chevy Silverado, same thing, Speed sensor went bad, changed it, then a grinding then my wheel cover started turning a dark color, wheel bearings went bad, changed both sides and all was good. A decent Hub assembly will cost you about $150 - $200 at the parts store. If you buy the cheap ones for like $75, you'll be changing again in about 1 year or just after warranty expires...First hand experience.

ABS and BRAKE light on


Hi Timothy:
You will want to have it scanned for any trouble codes to see what area the problem may be in. Just let us know what the code(s) are and we can go from there.

The only thing that I can figure is that it may be that the ABS is activating at low speeds, as there is a bulletin that mentions that with no trouble codes. Wheel speed sensors, dirty.

Bulletin No.: 02-05-25-006B
Date: January 05, 2006
TECHNICAL
Subject: Antilock Brake (ABS) Activation At Low Speeds (Clean Wheel Speed Sensor Mounting Surface)

Models:
1999-2000 Cadillac Escalade
1995-1999 Chevrolet Silverado (Old Style)
1995-2000 Chevrolet Suburban, Tahoe (Old Style)
1995-2003 Chevrolet Astro Van, Blazer, S10
1995-1999 GMC Sierra (Old Style)
1995-2000 GMC Yukon, Yukon XL (Old Style)
1995-2001 GMC Envoy, Jimmy
1995-2003 GMC Safari Van, Sonoma
1995-2001 Oldsmobile Bravada

Supercede: This bulletin is being revised to update the correction and warranty information. Please discard Corporate Bulletin Number 02-05-25-006A (Section 05 - Brakes).

Condition: Some customers may comment on ABS activation at low speeds, usually below 8 km/h (5 mph). Upon investigation, the technician will find no DTCs set.

Cause: The cause of this condition may be an increased air gap between the wheel speed sensor and the hub reluctor ring due to rust and debris built up on the sensor mounting surface.

Correction:
Measure AC voltage and clean wheel speed sensor mounting surfaces.
1. Raise the vehicle on a hoist.
2. Disconnect both the front wheel speed sensor harness connectors.
3. Place a DVM across the terminals of each sensor connector.
4. Rotate the wheel with hand speed and measure the ACmV's. The reading should be at least 350 ACmV's.
5. If the reading is between 200 and 350 ACmV's, remove the wheel, caliper and rotor in order to gain access to the speed sensor.
6. Remove the wheel speed sensor and plug the hole to prevent debris from falling into the hub during service.
7. Clean the wheel speed sensor mounting surface using a wire brush, sand paper, emery cloth, ScotchBrite(TM) or other suitable material. Be sure to thoroughly clean the wheel speed sensor surface. There should be no rust or corrosion.
8. Check the sensor head to determine if it has been warped/distorted due to the corrosion build up or other causes. Check the mounting surface on the sensor head for flatness by placing it on the edge of a metal machinists scale or other suitable straight edge to measure the flatness. Check the sensor for flatness in multiple (minimum 3) positions/directions. If the sensor head is distorted, replace the sensor.
9. Apply (spray) two thin coats of the specified rust penetrating lubricant (corrosion inhibitor) to the complete sensor mounting surface on the bearing hub. Allow to dry for 3-5 minutes between coats. Use ONLY Rust Penetrating Lubricant, P/N 89022217 (Canadian P/N 89022218).
10. When the corrosion inhibitor is dry to the touch (about 10 minutes), apply a thin layer of bearing grease to the hub surface and sensor 0-ring prior to sensor installation. Use ONLY Wheel Bearing Lubricant, P/N 01051344 (Canadian P/N 993037).
11. Install either the original sensor or a new one in the hub and secure the sensor. Ensure that the sensor is seated flush against the hub.
12. Install the rotor, the caliper and the wheel.
13. Place the DVM across the sensor terminals and recheck the voltage while rotating the wheel by hand. The voltage should now read at least 350 ACmV's.

Hope this helps; also keep in mind that your feedback is important and I will appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

1993 gmc sierra 1500 abs brake light on


the most common cause is wheel speed sensor or sensor wiring not reading proper wheel speed.it is also possible the reluctor wheel inside front bearing is clogged with rust and debris and unable to send magnetic pulse. This can be tested with scanner to determine wheel in question.ohm meter can be used to test sensor and reluctor pulse.

ABS problem with GMC 2002 Sierra


its a low speed abs activation the problem is in the front sensors they need to be cleaned or replaced they [or one] probably has some corrosion on the sensor --[the 99 chevy tahoes had a limited recall over this issue and the fix was to remove and clean the abs sensor or if to corroded replace ] this problem doesnt set off an abs code or trouble light also sometimes the abs will activate by itself at under 4 mph without even touching brake

When breaking the abs goes off when you get down to about 5miles


rust build up between your wheel speed sensor and knuckle in 1 or both of your front hubs likely causing vehicle to think lockup has occured at low speeds. replace your faulty wheel speed sensor/s. monitor with scan tool that shows individual wheel speed of front sensors and replace the 1 that does not read the same as the other 2

2002 gmc 2500hd 4wd abs problems


the problem is most likely a wheel speed sensor at one of the front wheels. retrieving a code in the abs system could pinpoint which wheel it is. i believe the wheel speed sensor is part of the bolt on front wheel bearing assy. if you plan on doing this yourself and are mechanically inclined. you will need an a/c volt meter to check sensors. let me know if i can assist further.
