DTC P213B:00 [PCM (SKYACTIV-D)]

Home  id0102t5738300

Outline

System malfunction location	Circuit malfunction in LP-EGR control valve DC motor control system
Detection condition	•  When the following conditions are met, if the LP-EGR control valve duty value is 90 % or more for 2 s, the PCM determines that there is a LP-EGR control valve control system range/performance problem. Preconditions ―  LP-EGR control: during feedback control ―  The following DTCs are not detected: •  LP-EGR control valve DC motor control system: P045B:00 •  LP-EGR control valve position sensor: P0407:00, P0408:00 •  Intake shutter valve control device in PCM: Run error: P16A3:00
Fail-safe	•  PCM restricts engine torque. •  Limits the maximum engine speed. •  Inhibits the DENOx/DESOx control. •  Inhibits the diesel particulate filter regeneration control. •  Inhibits the EGR control. •  Inhibits engine-stop by operating the i-stop function.
Possible cause	•  LP-EGR control valve connector or terminals malfunction •  PCM connector or terminals malfunction •  Short to power supply in LP-EGR control valve control circuit •  Short to ground in LP-EGR control valve control circuit •  LP-EGR control valve 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 RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY •  Verify related Service Bulletins, on-line repair information, or Service Information availability. •  Is any related Information available?	Yes	Perform repair or diagnosis according to the available information. •  If the vehicle is not repaired, go to the next step.
		No	Go to the next step.
3	INSPECT LP-EGR CONTROL VALVE 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.
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.
5	INSPECT LP-EGR CONTROL VALVE CONTROL CIRCUIT 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.
6	INSPECT LP-EGR CONTROL VALVE CONTROL CIRCUIT 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.
7	INSPECT LP-EGR CONTROL VALVE FOR MALFUNCTION •  Inspect the applicable part. (See LP-EGR CONTROL VALVE INSPECTION [SKYACTIV-D 1.8].) •  Is the part normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See LP-EGR CONTROL VALVE REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED •  Install/connect the part removed/disconnected during the troubleshooting procedure. •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Replicate the vehicle conditions at the time the DTC was detected using the following procedure. ―  Perform the KOEO self test. (See DTC INSPECTION.) •  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 [(E)].) 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 [SKYACTIV-D 1.8].)
		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.
