Pcm Code P058 - Pass-Key Fuel Enable Problem: Notes
WARNING: This page is about a different car, the 1993 Cadillac Seville and 1993 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.
PASS-Key system enables engine operation by allowing starter to engage and issuing a fuel enable signal to PCM. 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.
