Can't find Brake pressure sw.

Post by Sveedy » Sat Jun 20, 2020 5:06 pm

I have been having an intermittent ABS light coming on issue, which I thought was simply a bad module. I replaced the ABS module but still had the same problem.
Matt at Midwest scanned my old module and a code for a faulty brake pressure sensor came up. I went to look at it and I just can't seem to find it. But I do see this plug. Is that where the sensor is supposed to be ? I looked around the area and don't see any wiring/plug that is disconnected.

That’s just a tap for a clutch fluid switch, capped off if you have a slush box.

Is the code for a fluid pressure switch or the pressure switch on the brake booster?

From what I've seen online, that seems like where my brake pressure sensor should be. I just found a short wire pigtail w/ plug tucked up behind part of the harness, which reaches that plugs location. I don't see anything else coming off the booster except the ABS unit. I guess since the part is no longer available, I'll hit a junkyard and that should clear this up.
