Engine Oil Level Sensor

Has O Ring Seal At Top Of Threads. If your engine oil level sensor has failed, it will usually provide a "false positive," meaning it will incorrectly report that your engine oil is low even if it isnt. This can lead to some operators adding more oil than is necessary to the engine, which causes damage to major systems. Whether you suspect the oil level sensor or not, a technician should diagnose the fault in your Ford to prevent engine damage.
