What does 'Ford Engine Malfunction - Service Required Immediately' mean?
1 Answers
Engine malfunction requiring immediate service indicates that the computer self-diagnosis has detected an engine fault, necessitating instrument-based detection of the engine system to read the fault code. Reasons for the engine fault light activation: 1. Sensor malfunction: Issues with sensors such as the coolant temperature sensor, crankshaft sensor, or oxygen sensor. 2. Spark plug and fuel system faults: Problems with spark plugs, ignition coils, fuel pump, or fuel line blockages. Some owners may notice the engine fault light illuminating immediately after refueling - this occurs when substandard fuel from non-compliant gas stations is used. While this condition doesn't affect vehicle operation, it may cause engine damage.
