	Sensor/unit used	•  Fuel pressure sensor (integrated with fuel injector No.1) •  Fuel pressure sensor (integrated with fuel injector No.2) •  Fuel pressure sensor (integrated with fuel injector No.3) •  Fuel pressure sensor (integrated with fuel injector No.4)
Fail-safe	•  Not applicable
Vehicle status when dtcs are output	•  Illuminates check engine light.
Possible cause	•  Fuel injector No.1 malfunction •  Fuel injector No.2 malfunction •  Fuel injector No.3 malfunction •  Fuel injector No.4 malfunction •  Fuel leakage or clogging in fuel line •  PCM malfunction

Function Explanation (DTC Detection Outline)

Repeatability Verification Procedure

―  Drive the vehicle on flat roads under the following conditions 4 times repeatedly.

Caution

•  Observe legal speed limits when driving the vehicle and perform the procedure in a location where safety can be assured.

1.  Accelerate to 15 km/h{9.3 mph} and decelerate to 0 km/h{0 mph}.

2.  Wait for 20 s while idling.

3.  Accelerate to 30 km/h{19 mph}, and decelerate to 0 km/h {0 mph} after driving the vehicle while maintaining the speed for 20 s.

4.  Wait for 20 s while idling.

5.  Accelerate to 50 km/h{31 mph}, and decelerate to 0 km/h{0 mph} after driving the vehicle while maintaining the speed for 20 s.

6.  Wait for 20 s while idling.

PID Item/Simulation Item Used in Diagnosis

Function Inspection Using M-MDS

Step	Inspection	Results	Action
1	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 the next step.
2	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.
3	PURPOSE: DETERMINE INTEGRITY OF FUEL PRESSURE SENSOR •  Inspect the fuel pressure sensor. (See DTC INSPECTION.) •  Is the fuel pressure sensor normal?	Yes	Go to the next step.
		No	Go to Troubleshooting Diagnostic Procedure to perform the procedure from step 1.
4	PURPOSE: DETERMINE INTEGRITY OF FUEL TEMPERATURE SENSOR •  Inspect the fuel temperature sensor. (See DTC INSPECTION.) •  Is the fuel temperature sensor normal?	Yes	Go to the next step.
		No	Go to Troubleshooting Diagnostic Procedure to perform the procedure from step 1.
5	PURPOSE: VERIFY OTHER RELATED DTCs •  Switch the ignition OFF, and then switch it ON (engine off). •  Display the DTCs using the M-MDS. (See DTC INSPECTION.) •  Have DTCs other than P02CD:00, P02CF:00, P02D1:00, or P02D3:00 been stored, or has pending code been stored?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D)].) Go to Troubleshooting Diagnostic Procedure to perform the procedure from step 1.
		No	Go to Troubleshooting Diagnostic Procedure to perform the procedure from step 1.

Troubleshooting Diagnostic Procedure

―  Determine the integrity of the fuel injector.

―  Perform the inspection of the fuel system piping.

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

Step	Inspection	Results	Action
1	PURPOSE: INSPECT FUEL INJECTOR FOR MALFUNCTION •  Inspect the applicable part. (See FUEL INJECTOR 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 FUEL INJECTOR REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)
2	INSPECT FUEL LINE FOR FUEL LEAKAGE OR CLOGGING •  Inspect the following fuel lines of each cylinder for fuel leakage or clogging. ―  Common rail and fuel injector •  Is the fuel line normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location, then go to the next step.
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.
