wheel sensor
hello
this is driving nuts the abs light is on with the traction control and sta blelink it has a coo35 code ? how I take my meter and set it to 2k ohm's and I get nothing now this is the right front so I check the left same thing no reading the same on the left rear could I have three bad sensor or am I doing something wrong ,this all started with the traction light going on when driving then I let it set for about 10 minutes and everthing works great |
You can check for opens with an ohm meter but I use a much lower scale. I think it is something like 50 ohms. The wiring may only open on turns so check that also. You can also check with the ac volt meter, they make a few volts when you spin the wheel.

thanks for the reply I have set my meter at 200 ohm's still no reading
|
Are you disconnecting the sensor at the hub and back probing the connector?
|
sensor
yes I don,t think that this sensor can be checked by using ohm's
|
What year is your Vue? If it is the latest version GM may have switched systems from what is on my car.

its a 2009 xe with a 2.4 l you might be right thanks for the reply

look at this, your car is very similar.
Andy On some 2007-2010 OUTLOOK; 2007-2011 Acadia; 2008-2011 Enclave, CTS/CTS-V; 2009-2011 Traverse;the following DTCs or Symptom codes may be set: C0035, C0040, C0045, C0050, with symptom bytes 18, 5A, 0F. The ABS, Service Traction Control System, and/or Service StabiliTrak lights also may be illuminated. This condition may be caused by single or multiple pieces of ferrous metallic debris stuck to the wheel speed sensor magnetic encoder ring. Instead of a traditional mechanical-type tooth tone wheel, some new model vehicles use a wheel speed sensor tone wheel made of a magnetized nitrile rubber ring, typically brown in color. This magnetic encoder ring is now part of the inboard bearing hub assembly The magnetic encoder consists of multiple North and South pole pairs surrounding the outer circumference. When the magnetic encoder ring rotates and passes by the wheel speed sensor head, it generates a sine wave in the wheel speed sensor. The wheel speed sensor converts an analog signal to a digital square wave, and typical digital signal values switch between 7mA (Low) and 14mA (High) DC current. Encoder Ring Cleaning Inspect and clean any debris from the encoder ring using the following procedure. This inspection and cleaning procedure is supporting information to with symptom bytes 18, 5A, 0F can be repaired by removing or cleaning any accumulated debris on the magnetic encoder ring, located on the inboard side of the bearing hub. TIP: Most repairs can be performed without replacement of the bearing hub assembly or wheel speed sensor. Be careful not to damage the bearing outer seal when brushing or cleaning the magnetic encoder debris. Do not use any type of magnetic tool to remove the debris from the bearing magnetic encoder. An external magnet can damage the encoder. 1. Based on the specific EBCM Wheel Speed Sensor DTC code, inspect the appropriate corner magnetic encoder ring for possible debris. • C0035 Left Front Corner • C0040 Right Front Corner • C0045 Left Rear Corner • C0050 Right Rear Corner 2. If debris is found, gently use a dry nylon soft bristle brush to remove the foreign debris from the magnetic encoder ring. If debris was removed, proceed to step 3. If debris still remains, wash the encoder ring using a mild soap detergent and wipe dry. 3. Connect a scan tool to the vehicle. Turn on the ignition. Clear the DTCs. 4. Perform vehicle diagnostic repair verification procedure for DTC C0035-C0050. Refer to the appropriate Service Information. the SI wheel speed sensor diagnostic mechanical fault table. In most cases the DTCs C0035-C0050 |
wheel sensor
thank you very much looks like a good place to start . I did notice that the right front bearing you have to use both hands to turn it and that's with it in my vice on the bench ,the left turns real free not to take a chance I ordered both but I will look for metal in them both thanks again
