Camshaft and Crankshaft Position Sensors Relearn

摘要

A recurring "Check Engine" light following the replacement of a camshaft or crankshaft position sensor could mean the relearn process was not performed. When the relearn process is not done, it could keep the PCM from recognizing an engine misfire or a problem with the cylinder, and it could even lead to the engine running in "reduced power" or "limp mode" in rare cases.
