Need some help here please. I have 2005 S-CREW FX4. Build date 12/04. I have 13,500 miles on her and the ABS light came on 1200 miles into a trip while towing a vehicle. Got it to the shop and they replaced the right rear speed sensor. I got on the road again and about 1000 miles into another trip the ABS light came back on again. Took it to the dealer and the center speed sensor was replaced. I noticed this happening AFTER I had my 33's placed on the truck. The ABS light never came on before the larger tires. I have not corrected the speedometer. Could the sensors have been defective or will I keep blowing sensors with the bigger tires without a recalibration. Oh, and the dealer said they could not recalibrate for larger tires???? I thought they could recalibrate up to 35's ?? Thanks

 

The ABS module knows what size tires the truck came with through the PCM. You need to have the correct tire size programmed in to the PCM. The ABS knows what speed (revolutions) you should be going according to the (stock) tire size and it is seeing the difference as a sensor error. Your ABS light should go out once the tire size is correct in the PCM. Just ignore that man (the PCM) behind the curtain, he is the one who knows all and controls all about your truck.

 

Thanks, I thought I could fool the "OZ" behind the curtain. I guess I'll start looking into a tuner to fix the tire diameter. Thanks
