SOURCE: How do I replace a bad(??) ABS speed sensor?

I cleared this by replacing the sensor mounted on top of the rear differential housing.

If you turn the key and nothing happens, and you bought a new starter and nothing happens (you just wasted $80 or more) check the starter relay by taking a screw driver and touching both the posts at the same time with the screw driver. but first turn your key to the run position (or the click before you would hold it to start) then touch the realy with the screwdriver. to find the relay first follow the positive (red,or "hot") battery cable to a little box type thing probably mounted to the inside of the quarter panel on which side you battery is if still nothing somethings wrong if it starts well you know what it is then go to the parts store and pick one up.

SOURCE: abs activates just before truck

This is a condition known as over active ABS. GM has a technical service bulletin for this. Basically what it say is to remove the front wheel speed sensors from the hubs, clean the mating surface between the sensor and the hub, apply some di-electric grease over the cleaned area, and reinstall the sensor.

You can try this on the front sensors and see if the problem goes away. I will warn you that you need to be very careful removing the sensor from the hub as they can break off. If it breaks off in the hub you will need to replace the hub and bearing.

You can also check to see if one of the front wheel bearings is loose. with the tire off the ground grab the tire at the 12 and 6 position and push/pull. if the wheel moves and you can see the rotor moving also than the wheel bearing may be sloppy enough for internal exciter ring to get an excessive gap from the abs sensor.

The easiest thing to do is look at wheel speed data on a higher end scan tool. When the symptom happens you will see the wheel speed drop out. Whatever wheel drops out is the wheel that needs to be checked.

Hope that helps.

Check your MAP and TP sensors. Your throttle body may be having trouble determining position and is compensating by adjusting RPMs.

1999 chevy silverado 5.3 starts then dies out


check to see if you can hear a loud sucking sound (air) going into the throttle body when the engine starts then dies. if you hear alot of air being sucked into the throttle body, replace the Coolant Temperature sensor located close to the thermostat housing on top of the intake manifold. If this $12.00 part goes bad, it will cause the same symptom you have described. You can check the sensor for correct reading by using a scan-tool.

2006 chevy silverado abs light comes on goes off comes on goes off


Hi...your problem might be coming from your front wheel bearing hubs. They are know to cause this problem as they wear out and eventually have to be replaced.

Brake pedal a.b.s pulsation at slow speeds on dry road.It wont do it all the time. It is on a 2000 chevy silverado 1500 4x4. I can hear the abs kick in when this happens.


You may see the abs light come on in your dash. I would plug a OBD II reader in and retrieve the codes.
I would say you either have a sensor that has gone bad or possibly a wire is shorting.
You can see the wheel sensor if you turn your wheels, and look down by the wheel hub bearing.
You can here the abs go whrrrrrrrr, when you step on the brake, and your braking flucuating.
Please let me know what you find.

First, Find a new dealer!! Then contact Chevrolet/GM customer service.. this should NOT continue to happen.. there is something causing this to repeatedly happen.. Your current dealer is not interested in finding the origin of the problem,,just taking your $$$$ and waiting for you to return and take more of your $$$$.
Elevate this issue within GM and get a service rep involved!!

You could remove the dash and remove the bulb... but a scan will show it...
