Note On Intermittents

If Code P058 is set intermittently the following could be a cause:

  1. Intermittent short to ground or voltage on CKT 229.
  2. Intermittent open in CKT 229.
  3. Intermittent loss of power or ground to the PASS Key® Module. The PASS Key® Module reads the ignition key once each ignition cycle when the ignition is first turned on, therefore, faults in the key pellet and circuits to the ignition lock cylinder can cause a no start condition but cannot cause a stall or Code P058.
