Anyone know if my 2002 chevy express 4.3L has a digital ratio adaptor controller? It's a device used to convert the analog signal from the speed sensor into a digital signal that the EBCM can use. If , yes, where is it located? Thanks for any info.

PCM usually controls that function. The analog signal goes into the PCM, and goes out to various modules as a digital signal

what are you trying to add?
