You posted this in the 2000-2005 section, which has a VERY different ABS system.
I'll move this to 92-99 for you.
The problem is not a wheel speed sensor. That inlet valve is inside your PMV. Pressure Modulator Valve assembly. It'* the gizmo underneath your airbox (where your filter lives) that has brake lines coming in and out of it.
Last I checked, dealer price was about $750 for it. Wreckers around $200. It is not a repairable part. You need to replace it. How was this code determined?
I have the same problem on my 93. I live without it.
