Last week, on my ride home from work, I pressed the brake and noticed a spongy pedal and a weird noise. Like a stutter stop? It felt as though the Anti-Lock Brakes had locked up, but I wasn't even pressing hard. The best way to describe it is when you press your brakes going over ruts? Hard to explain! Then it went away just as quickly as it started.

The following day, I headed to work, and my ABS Light came on. 45 miles later, I stopped for Coffee and shut the truck off, got into the vehicle and the light wasn't on after starting it back up. I made it another 45 miles and the light came on again. I left for home in the evening and the light was off. About 10 miles down the road, I accelerated quickly and the light came back on again, and didn't go off. So I changed my rear diff fluid, and pulled the rear wheel speed Sensor and cleaned it pretty good too. It lasted about 20 miles and it's on again. Won't go off. (I had this exact issue on my 99 Expedition a few years ago) Cleaning the sensor worked for a little while, but eventually had to replace the rear wheel speed sensor.

I dont' want to just throw parts at this thing, I'd like to get it fixed correctly. Is there a way to test this sensor or do I need to have a shop just pull the DTC's for the ABS system? Is there a tool that I can buy that will save me in the long run? One that doesn't break the bank?

 

Get Autoenginuity from Riff Raff you won't be disappointed. Best money I ever spent

 

You need to have the codes read to get the ABS problem corrected for sure, whether you get them read somewhere or get Autoenginuity. AE is pricy at ~$375+/- but being the information guy you are it would be like a toy for you.

 

$359 and free shipping. Believe me, it will come in handy more than once. It is well worth the investment.

I have it. I just wasn't sure of the exact price from Clay, but that's where I'd get it from if I didn't.

 

hmmm, I just ordered $400 in Rancho RS9000XL shocks today. Looks like I'll be out more with the AE! Thanks everyone.

 

You can try the easy and simple way and clean all three plugs.
Two up front and the one in the rear. I keep getting a right
front sensor error and every time I clean and reseat the plug.
I also put some dielectric grease in the plug.
Right now I do have an advantage over you with the Snap-On
Solus scan tool.

you can also ohm the sensor and see if it is excessive or reading ol

 

Thanks, I did clean the rear sensor and put dielectric grease. I do this on all plugs, even on my ATVs. It is still going off when I let the truck sit overnight, and then it comes back on. I'll need that AE, but I'm struggling to keep the wife from getting frustrated... lol. Maybe I'll do as you suggested and clean the others. Just had the radiator start leaking this morning.
