ABS Speed Sensors...Or something more?
Hi All. My names Jake, I am new to the forum and would like to pick your brains on something. Problem: The ABS light came on a week ago. And a little history: the truck has 114,000 miles. The truck is a 2003 Ranger FX4 4.0L. I've only seen this light come on once before, that was about 6 months ago and my front left wheel bearing failed about 20 miles later while on the interstate. Needless to say, that bearing assembly is replaced. After the abs light came on a week back, I had it hooked up to a diagnostic computer, which threw 2 codes. It was saying that both the front right and left abs speed sensors were bad. I jacked the front end up, tried rocking the wheels and there is no play to indicate a worn wheel bearing. I also went for a long drive and measured the tempurature of the hubs with an infared thermometer. both were around 110*. No unusual noises while on the road either. The thing that gets me is that both the right and left abs sensor went bad (according the the computer) at the exact same time. What are the chances? could it be an issue elswhere further up the abs system? has anyone experienced this? Thanks.
