Pcm Code E058, Pass Key Control Problem: Description
WARNING: This page is about a different car, the 1992 Cadillac Seville and 1992 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.
Once engine is running, PCM constantly monitors fuel enable signal from pass key module. PCM will not cancel fuel injection once it has seen a proper pass key module signal; therefore, stalling conditions cannot occur as a result of a pass key malfunction.
