Got p0320 code on a ford ranger 4x4 2004, 4.0 liter engine. What is the usual fix?

Question

Truck started again after about a half hour.

Answer 1

This code is for the ignition speed signal from the engine to the pcm.This is controlled by the crank position sensor. Typically the issue is with the crank sensor itself. The wiring must be ohmed from the crank sensor to the pcm.
