Operation Section 1 ± 30 8. ENGINE ECU DIAGNOSTIC TROUBLE CODES (DTC) 8.1 DTC Table (1) 2004, 2007 Model DTC Code Detection Item DTC Description Remarks P0045 Variable Nozzle Turbo (VNT) Malfunction Issued when the VNT actuator is malfunctioning. P0087 Rail Pressure Control Abnormality (Continuously Below the Standard Value) Issued when actual rail pressure in relation to the command rail pressure is continuously low. Check the fuel filter for clogging, the supply of fuel to the pump, as well as for any foreign matter intrusion.
P0088 Rail High-Pressure Control Abnormality (Pressure is Continuously Above the Standard Value or Pressure Momentarily Becomes Abnormally High) Issued when rail fuel pressure is abnormally high, or when actual rail pressure in relation to the command rail pressure is continuously high. Possible causes include faulty contacts in the rail pressure sensor line, noise, lack of injection, and/or a supply pump malfunction. P0102 Mass Air Flow (MAF) Meter Malfunction (Lo) Issued when the MAF meter is malfunctioning. Possible causes include a sensor malfunction, or an open/short circuit to ground in the wiring harness. P0103 MAF Meter Malfunction (Hi) Issued when the MAF meter is malfunctioning.
Possible causes include a sensor malfunction, and/ or a short circuit to +B in the wiring harness. P0108 Boost Pressure Abnormality Issued when boost pressure cannot be correctly detected. Possible causes include a sensor malfunction and/or a short circuit in the wiring harness. P0112 Intake Air Temperature Sensor Malfunction (Lo) Issued when temperature cannot be correctly detected. Possible causes include a sensor malfunction, and/or a short circuit to ground in the wiring harness. P0113 Intake Air Temperature Sensor Malfunction (Hi) Issued when temperature cannot be correctly detected. Possible causes include a sensor malfunction, or an open/short circuit to +B in the wiring harness.
P0117 Coolant Temperature Sensor Malfunction (Lo) Issued when temperature cannot be correctly detected. Possible causes include a sensor malfunction and/or a short circuit to ground in the wiring harness.
