Engine - 2.4L Duratorq-TDCi HPCR (103kW/140PS) - Puma - Engine Diagnosis and Testing Overview As diagnosis of the different areas of the engine is covered in other sections and by general procedures, this section is limited to an oil pressure test. For specific areas of the engine, refer to the general procedures in this section and the relevant section of the manual. Inspection and Verification 1. 1. Verify the customer concern. 2. 2. Visually inspect for obvious signs of mechanical or electrical damage. Visual Inspection Chart Mechanical Electrical Engine oil level Coolant level Transmission fluid level Fuel level Coolant leaks Oil leaks Fuel leaks Visibly damaged or worn parts Loose or missing nuts or bolts Fuel contamination/grade/quality Sensor fitment/condition Viscous fan and solenoid Routing of pipework etc. to avoid vibrations Contact anywhere between the driveline and chassis Fuses Wiring harness Electrical connector(s) Injectors Glow plugs 5 volt sensor supply Sensor(s) Viscous fan solenoid Engine control module (ECM) 3. 3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. 4. 4. Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto the symptom chart or DTC index. Oil Pressure Check • NOTE: Prior to checking the engine oil pressure, a road test of 6 miles (10 kilometres), must be carried out. Do not attempt to attain engine normal operating temperature by allowing the engine to idle. 1. • WARNINGS: The spilling of hot engine oil is unavoidable during this procedure, care must be taken to prevent scalding. Failure to follow this instruction may result in personal injury. Wear protective gloves. 1. Remove the oil pressure sensor. REFER to: Engine Oil Pressure (EOP) Sensor (303-14 Electronic Engine Controls - 2.4L Duratorq-TDCi HPCR (103kW/140PS) - Puma, Removal and Installation). 2. 2. Install the oil pressure gauge and the oil pressure gauge connector. |
