brake and abs light, Speedo too

[hex0rz]

Today I use the truck to go to work and the abs light and brake light stay on. No biggie, it's happened before and went away. Everything still functioned and had braking power. Then, when I'm driving, I lose my Speedo intermittently.

After work, lights were still on, but Speedo wouldn't work until after 20mph.

What is it, my Speedo sensor, or an and sensor?

I've read a little, and sounds like there is something on the transmission and diff.

Any ideas?

I had the brake light on mine do that and it was the speed sensor

On the rear diff. It has one bolt that holds it and has an oring around

The sensor and slides down in from the top left side of the pumpkin

Not a hard job at all. I had rust on mine to clean off. Do you have any codes ?

I'm currently running with my BRAKE and ABS lights on. I know my front sensors are bad and need replacing. As for you Hex you issue is going to be a rear sensor being your speedometer.

Yup, go oem from Rock Auto. It's a wells or airtex part which is the oem part.

Couldn't wait for rock auto. Went to Napa and got theirs. Problem fixed!
