97 shortbed single cab 2wd ranger with 2.3L and the REAR ANTILOCK BRAKES. I got an ABS light, grounded the fuse in the box and got code 12. I'm trying to troubleshoot the sensor in the brake fluid resivior. It has a three prong connector. On the resivior, the pin closest to the front of the truck, well call it pin #1 I get continuity to pin #2 and nothing on #3. Thinking that i would get a variable ohm reading on it while i push the float i tested each pin while moving the float and nothing. Just constant continuity between pin one and two. On the plug side that goes to the harness, the part that plugs into the resivior I get battery voltage on pin #1, like 105 ohms on pin #3 and no continuity to ground on #2.

I thinking that cause there is no change in ohms across that float its bad and that's why it's throwing the code 12. Somebody wanna check there's and compare notes???

Is there a way to reset the ABS codes so I can see if it comes backa or not? You guys think I'm on the right Track????

Any opinions or ideas are appreciated. Beauty of the internet is I don't like it, I don't have to read it.

 

The code 12 is for low fluid during an ABS stop, so is the master cyl fluid level ok????

Are both the red & yellow dash brake lights lit????

Here is a link with illustrations on pulling codes & trouble shooting our brake system that might prove helpful. at the bottom of the page are other links to Ranger ABS questions & answers that also have helpful info. Ford Ranger ABS Light

 

Just the abs light is on, not the brake light. Fluid level is definitely OK!

I jumped the plug so the computer would think the resivior was full and the light went off. I think its the fluid level sensor.

 

I have a similar problem and was wondering which of the 3 wires did you jump together to get the light off?
