Powertrain Control Module (Pcm)
PCM is located under instrument panel on driver's side. It receives and processes data from sensors, switches, and other components. PCM generates output signals to control fuel injection, spark timing, emission systems, and other engine functions.
NOTE:
Components are grouped into 2 categories. First category is INPUT DEVICES, which control or produce voltage signals monitored by PCM. Second category is OUTPUT SIGNALS, which are components controlled by PCM.
