ABS/Speedometer

[boomer64]

I have a 2000 Ranger and it went through a lot of water. Now when I start it the ABS and check engine lights come on but go off. When I hit the brake or use the turn signal the speedometer fluctuates to 0 and back. Any ideas on what the problem could be?

I would check ground connections that got soaked. Use an ohm meter and check from cable to the frame. I would also clean connections to the wheels the water may have loosened some of them.
Also clean connections to the transmission speed sensor.

The speed pickup is in the rear end. Check there for water in the plug or something loose in that area....Mike

I had a similar problem. ABS light came on and I noticed that at low speeds, my speedometer was malfunctioning. Got my OEM and found out that ABS is interconnected with the speedometer. I replaced the sensor (located right above and fwd of the differential) Problem solved.

There's a juction plug under the driver's seat, accessed from ouside. Moisture can get into the plug fron inside the cab, causes all sorts of problems.

Follow Mike's advice. I had the speedometer going nuts and took out the differential pickup and cleaned it off. Works like champ for the past 3 years.
