As you may know, I’m an ASE Certified tech. At our shop, we work on many different makes and models of vehicles. I’m definitely not a Ford Specialist but I do work on a whole lot of them! I’m going to go ahead and say that’s just because there are so many of them on the road today!
That aside, we very recently had a 1999 Ford Ranger 4×4 Super Cab roll through our shop with an ABS light on. Almost immediately, I imagined it would be the speed sensor on the top of the rear axle as this is a common issue. After scanning her with the Genisys – we were given this code:
C1230: Speed Wheel Sensor Rear Center Input Circuit Failure
Turned out the initial suspicion of the rear speed sensor was correct. I replaced it with an aftermarket sensor from Advanced Parts which took all of 5 minutes and this took care of the problem. I cleared the code from the system and took her out for a spin. The ABS light has been out since.
I just wanted to share this bit of info as it’s a very common issue with these trucks, it isn’t very hard to repair at all and it’s pretty inexpensive. A job like this could be easily completed by a beginner DIY mechanic!
