ABS light on

[jeffro22]

My abs light has been on for a few days now. it was coming on and off for the past month or so. Any ideas on what to check. the brake fluid is full. I think one other time i had this problem and it was a sensor on the rear diff that need cleaning.

I am only speaking from an experience with my f150. I cleaned the speed sensor in the differential and had no luck. I put about 40,000 on it with the abs light on. Then i finally just replaced the sensor and also cleaned the sensors on both of the front wheels. Now im not sure which one fixed it but it was fixed after that. I was also curious if power braking could cause this issue as it came on shortly after i was messing around doing some burnouts. Either way i quit with the burn outs after i replaced the sensor.haha

thanks, I will check the same things as soon as i get some free time.

Ok, I cleaned the connection to the rear sensor and it didnt help. I also pulled the sensor out, but it looked clean. Light is still on. Should I replace rear sensor or look towards front sensors.?

WIll the ABS light allow a code to be pulled that will point me in the right direction?

Did you check the front wheel speed sensors? I would pull them and clean them before i bought the rear sensor. I dont remember how much the rear one is. Clean the front sensors and disconnect the batt for a few mins. If this doesnt help i would try to get it on a scanner. I dont know if autozone or advance or any other auto chains can check the abs system. I think i tried when i was having issues and they couldnt help. I just replaced the rear sensor and it happened to fix the problem, but as i said earlier my light came on shortly after some horsing around, and it was on a f150.
Good luck, let us know what you find.

Cycle the key about three times. Does some sort of reset in the computer. Cleared mine and has never came back.

Oreillys can check k it. Mine is the pass side front. I think the ac dripping on the connector is causing mine

[jeffro22]

when cleaning the sensors, are you cleaning the actual sensor or the connection? I checked the front passenger and cleaned teh connection but no luck so far.

Oreillys is a little bit of a drive, but i will call and check to see if they can check the sensor for me. thanks for the suggestion!

Can you raise the truck and check the wheel bearings. In my recent past on our Explorer and F-150 I found that bad wheel bearings have been the cause of this problem.

[jeffro22]

yes, i will go ahead and try to lift up the truck and check front wheels bearings
