PMS OFF/ABS Light
 
So I have a crazy gremlin going on that I can't figure out. Both lights come on randomly. Sometimes within a few blocks, sometimes within a few miles, and sometimes never. I have replaced the following: MAF, brake light sensor, fuel filter, air filter, oil change, AOS, plugs, coil packs, and tubes. I can turn off the PMS, and the ABS has yet to come on when the ABS is turned off. Has anyone experienced a bad PMS switch, or have any other ideas? Thanks in advance.

Might be a wheel speed sensor.

If you can get a diagnostic tool that will read the abs system, then you should be able to tell.

I know, I know It's almost 5... but I'm just not going to.
