Modern GM Misfire monitors

Tanner Diagnostician Kansas Posted   Latest   Edited  

Anyone have access to Theory of operation on 2011 and on GMs that use a 60x cranksensor? Is it still the same as older designs where the PCM detects a velocity change? Just a little confused how it works since they are using a single ckp signal..vs the older 12x and 24x.

Hello Tanner, I looked in All Data under DTC P0300 in the description section and found applicable information. They still use the crank sensor to monitor crankshaft speed changes.
