Set Pinion Factor
the speedometer. Namely it doesn't work. All other gauges work, but not
the speedometer. I pulled the PCM off so I could get better access to the
EGR Pipe to fix it. I noticed a sticker on the back of the PDM. It said
"Speedometer will not work unless pinion factor is set."
A Google produced a few results which leads me to believe that the Pinion
Factor must be set by a tech.
Am I reading that right?
