Earlier this summer the ABS light came on in the dash , done some trouble shooting and traced the problem to a faulty front wheel speed sensor. Replaced the sensor and the abs light in the dash went off, problem solved. Truck sat for most of the summer as i did some repairs to a rusted out wheel well and replaced a bad alternator and battery . Started it up yesterday for the first time in about 3 weeks , everything looked and sounded fine no warning lights in the dash , waited for the engine to warm up. Took it out for a test drive and when i pushed the brakes there was a fast pulsating feel to the brake peddle. Any ideas what it could be ?

 

did you get another ABS DTC ?

 

Thanks for replying Mark, only replaced the front driver side wheel sensor. Took it out for another spin today and now the ABS dash light is on again , could it be another sensor ? I bot both speed sensors for the front wheels even though the Forscan test said it was only the front left.

 

No just replaced the wheel sensor.

 

If the ABS light is on, there should be a DTC for it. Depending on the code, could be many things.
