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

Code P058 is an indication that PASS-Key(R) fuel enable input has failed after a good signal was received in a given engine run cycle. 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, testing for a circuit or PASS-Key(R) decoder module failure that would prohibit a positive fuel enable on future ignition cycles. PCM will not cancel fuel injection once it has approved within a given ignition cycle, therefore, stalling conditions cannot be result of a PASS-Key(R) system malfunction.
