Low/contaminated fuel Air leakage Low-pressure fuel system fault Blocked fuel filter Suction control valve fault Exhaust gas recirculation (EGR) valve fault Check the glow plug circuits. Refer to the electrical guides. Check the fuel level/condition. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the intake air system for leaks. Check the low-pressure fuel system for leaks/damage. Check the fuel filter, check for DTCs indicating a fuel injection pump fault. For EGR valve checks: REFER to: Engine Emission Control (303-08 Engine Emission Control - 2.4L Duratorq-TDCi HPCR (103kW/140PS) - Puma, Diagnosis and Testing). Rough idle Intake air system fault Low/contaminated fuel Low-pressure fuel system fault Blocked fuel filter Suction control valve fault Exhaust gas recirculation (EGR) valve fault Check the intake air system for leaks. Check the fuel level/condition. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the low-pressure fuel system for leaks/damage. Check the fuel filter, check for DTCs indicating a fuel injection pump fault. For EGR valve checks: REFER to: Engine Emission Control (303-08 Engine Emission Control - 2.4L Duratorq-TDCi HPCR (103kW/140PS) - Puma, Diagnosis and Testing). Lack of power when accelerating Intake air system fault Restricted exhaust system Low fuel pressure Exhaust gas recirculation (EGR) valve fault Turbocharger actuator fault Check the intake air system for leakage or restriction. Check for a blockage/restriction in the exhaust system, install new components as necessary: REFER to: Catalytic Converter (309-00 Exhaust System - 2.4L Duratorq-TDCi HPCR (103kW/140PS) - Puma, Removal and Installation). Check for DTCs indicating a fuel pressure fault. For EGR valve checks: REFER to: Engine Emission Control (303-08 Engine Emission Control - 2.4L Duratorq-TDCi HPCR (103kW/140PS) - Puma, Diagnosis and Testing). For turbocharger actuator checks: REFER to: Turbocharger (303-04B Fuel Charging and Controls - Turbocharger - 2.4L Duratorq-TDCi HPCR (103kW/140PS) - Puma, Removal and Installation). Engine stops/stalls Air leakage Low/contaminated fuel Low-pressure fuel system fault High-pressure fuel leak Suction control valve fault Exhaust gas recirculation (EGR) valve fault Check the intake air system for leaks. Check the fuel level/condition. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the fuel system for leaks/damage. Check for DTCs indicating a fuel injection pump fault. For EGR valve checks: REFER to: Engine Emission Control (303-08 Engine Emission Control - 2.4L Duratorq-TDCi HPCR (103kW/140PS) - Puma, Diagnosis and Testing). Engine judders Low/contaminated fuel Air ingress Low-pressure fuel system fault Suction control valve fault High-pressure fuel leak Fuel injection pump fault Check the fuel level/condition. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the intake air system for leaks. Check the low-pressure fuel system for leaks/damage. Check the high- pressure fuel system for leaks, check for DTCs indicating a fuel injection pump fault. Check the fuel injection pump: REFER to: Fuel Injection Pump (303-04A Fuel Charging and Controls - 2.4L Duratorq-TDCi HPCR (103kW/140PS) - Puma, Removal and Installation). Excessive fuel consumption Low-pressure fuel system fault Suction control valve fault Fuel temperature sensor leak High-pressure fuel leak Injector(s) fault Exhaust gas recirculation (EGR) valve fault Check the low-pressure fuel system for leaks/damage. Check for DTCs indicating a fuel injection pump fault. Check the fuel temperature sensor, fuel injection pump, etc. for leaks. Check for injector DTCs. For EGR valve checks: REFER to: Engine Emission Control (303-08 Engine Emission Control - 2.4L Duratorq-TDCi HPCR (103kW/140PS) - Puma, Diagnosis and Testing). DTC Index • NOTE: If a control module or component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval program is in operation, before the replacement of a component. • NOTE: Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system). |
