RPM Reference Signal

WARNING: This page is about a different variant/trim than selected.

The RPM is monitored by PCM through tach/pulse signals produced by either the ignition control module or crankshaft position sensor (Hall Effect signal, PM generator signal on DIS and IDI). These signals are used by PCM for determining control of timing, fuel delivery, EGR function and idle speed.
