Code P058, Pass-Key(R) Fuel Enable Problem: Notes

PASS-Key(R) 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(R) module. PCM will not cancel fuel injection once it has seen a proper PASS-Key(R) module signal; therefore, stalling conditions cannot occur as a result of a PASS-Key(R) malfunction.
