DTC P058A:00 [PCM (e-SKYACTIV)]

id300202027900

Outline

System malfunction location	Current sensor: Function malfunction
Detection condition	•  The PCM receives an error signal from the current sensor for 5 s.
Fail-safe	•  Refer to "DTC Table" and "Fail-safe Function Malfunction Contents Table". (See DTC TABLE [PCM (e-SKYACTIV)].)
Possible cause	•  Connector or terminal malfunction of the following parts: ―  Current sensor ―  PCM •  Short to ground or open circuit in current sensor power supply circuit •  Short to ground in current sensor LIN communication line •  Short to power supply in any of the following current sensor circuits. ―  Power supply circuit ―  LIN communication line •  Open circuit in current sensor LIN communication line •  Current sensor malfunction •  PCM malfunction

Diagnostic Procedure

Step	Inspection	Results	Action
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION •  Record the freeze frame data/snapshot data. Note •  Recording can be facilitated using the screen capture function of the PC.	—	Go to the next step.
2	VERIFY IF CURRENT SENSOR MALFUNCTION IS FALSELY RECOGNIZED BY DTC RELATED CAN OR LIN COMMUNICATION •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (e-SKYACTIV)].)
3	INSPECT CURRENT SENSOR CONNECTOR FOR MALFUNCTION •  Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) •  Are the connector and terminal normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
4	INSPECT PCM CONNECTOR FOR MALFUNCTION •  Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) •  Are the connector and terminal normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
5	INSPECT CURRENT SENSOR POWER SUPPLY CIRCUIT FOR SHORT TO GROUND AND OPEN CIRCUIT •  Inspect the power supply circuit for an open circuit and short to ground. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
6	INSPECT CURRENT SENSOR LIN COMMUNICATION LINE FOR SHORT TO GROUND •  Inspect the applicable circuit for a short to ground. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
7	INSPECT CURRENT SENSOR POWER SUPPLY CIRCUIT AND LIN COMMUNICATION LINE FOR SHORT TO POWER SUPPLY •  Inspect the applicable circuit for a short to power supply. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
8	INSPECT CURRENT SENSOR LIN COMMUNICATION LINE FOR OPEN CIRCUIT •  Inspect the applicable circuit for open circuit. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
9	INSPECT CURRENT SENSOR FOR MALFUNCTION •  Inspect the applicable part. (See CURRENT SENSOR INSPECTION.) •  Is the part normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1. (See CURRENT SENSOR REMOVAL/INSTALLATION.)
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED Caution •  Connect the negative battery terminal before connecting the current sensor connector. If the current sensor connector is connected first, the PCM may mistakenly recognize a signal from the current sensor and learn the battery condition incorrectly. •  Install/connect the part removed/disconnected during the troubleshooting procedure. •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Switch the main power to ON (READY on) and wait for 10 s or more. •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [L.H.D. (E)].) (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [R.H.D.].) If the CAN communication is normal, perform the diagnosis from Step 1. •  If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION.)
		No	Go to the next step.
Repair completion verification 2	VERIFY IF OTHER DTCs DISPLAYED •  Perform the DTC inspection. (See DTC INSPECTION.) •  Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
		No	DTC troubleshooting completed.
