Vehicle - 2001 Ford Ranger 4x4 with 4 wheel abs (1 sensor in each front wheel and one sensor in the rear axle I believe).
Quick history - About a year ago the ABS used to kick in at last moment when stopping - no ABS light, but the front ABS sensors were dirty I believe, so one of the sensors would read 0 mph while the other would still read 2 or 3 mph (used a scan tool to view datastream and verify this). This was causing the truck to think that one wheel was locking up and the abs would kick in. I took out the front sensors, cleaned them and the surface that the sensor mounts on to get rid of the rust buildup. This seemed to fix the problem.
Current problem - Last week I started my truck and during the systems check the overdrive light started blinking. I scanned it for a code and it had something to do with a transmission sensor. There were no driveability issues so I didn't think much of it - I cleared the code and everything was okay. That same day, I started my truck again and the abs light came on and the abs was essentially disabled. The brakes work fine, the fluid, fuse, etc are all okay. I scanned the truck for codes and got a C1145, C1155, and C1233. I drove the truck with the scan tool hooked up to it so I could monitor the wheel speed sensors and neither of the front sensors were giving any reading at all while the back sensor seemed to be working fine. I tried to clear the code and the scan tool would not clear it.
What is my next step? I can't believe both front sensors would fail at the same time? Is there a way to test the sensors before buying new ones? Do you think the ABS Module could be faulty and if so how can I verify that?
Thanks in advance for whatever you can do to get me going in the right direction.
