Home  id0102t5725700

Note

•  To determine the malfunctioning part, proceed with the diagnostics from "Function Inspection Using M-MDS".

Details On DTCs

Description	NOx sensor control circuit range/performance problem
Detection condition	Determination conditions	•  Any one of the following conditions is met: ―  Signal for open circuit in circuit from NOx sensor is received for a continuous 4 s ―  Signal for short circuit in circuit from NOx sensor is received for a continuous 4 s
	Preconditions	•  Battery voltage: 10.9—16 V •  CAN communication is normal at engine start for a continuous 20 s or more •  The following DTCs is not detected: ―  NOx sensor: U029D:00
	Drive cycle	•  1
	Self test type	•  CMDTC self test
	Sensor used	•  NOx sensor •  PCM
Fail-safe	•  Not applicable
Vehicle status when dtcs are output	•  DTC P2BAF:00 is also stored in the PCM and the vehicle speed is restricted.
Possible cause	•  NOx sensor connector or terminals malfunction •  PCM connector or terminals malfunction •  NOx sensor loose •  Open or short in NOx sensor CAN communication line •  NOx sensor malfunction ―  NOx sensor internal heater malfunction ―  NOx sensor control unit malfunction •  PCM malfunction

Function Explanation (DTC Detection Outline)

Repeatability Verification Procedure

1.  Perform the "COMPULSORY DIESEL PARTICULATE FILTER REGENERATION". (See COMPULSORY DIESEL PARTICULATE FILTER REGENERATION [SKYACTIV-D 1.8].)

2.  Idle the engine for 1 min.

Function Inspection Using M-MDS

Step	Inspection	Results	Action
1	PURPOSE: 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.
2	PURPOSE: INSPECT FOR OTHER RELATED DTCs •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Are any of the following DTCs displayed? ―  P220A:00 ―  U029D:00	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC P220A:00 [PCM (SKYACTIV-D)].) (See DTC U029D:00 [PCM (SKYACTIV-D)].)
		No	Go to the next step.
3	PURPOSE: 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 Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.

Troubleshooting Diagnostic Procedure

―  Perform a unit inspection of the NOx sensor.

―  Perform inspection of NOx sensor CAN communication related parts.

―  Verify that the primary malfunction is resolved and there are no other malfunctions.

Step	Inspection	Results	Action
1	PURPOSE: INSPECT INSTALLATION OF NOx SENSOR •  Inspect installation of NOx sensor. •  Is the NOx sensor installed securely?	Yes	Go to the next step.
		No	Retighten the NOx sensor, then go to repair completion verification. (See NOx SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)
2	INSPECT NOx SENSOR CAN COMMUNICATION LINE FOR SHORT OR OPEN CIRCUITT •  Inspect the applicable circuit for short or open circuit. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Replace the NOx sensor, then go to the next step. (See NOx SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
Repair completion verification 1	PURPOSE: 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. ―  Implement the repeatability verification procedure. (See Repeatability Verification Procedure) •  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	PURPOSE: 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.
