Oil Pump Replacement near Fresno, California

When diagnosing a possible loss of oil pressure, the technician will check the oil level first, then the engine will be inspected for engine oil leaks. This is because running low on oil can cause loss of oil pressure, and oil starvation issues. If the oil is full, and there are no leaks, the technician will connect to the vehicle with a computerized scanner to read sensor data, and compare that to actual conditions. Before the technician can suspect any mechanical failure, or start the engine, the engine oil pressure sensor must be proven to function properly. The technician will test the oil pressure sensor and associated electrical circuit, and determine if the sensor should be replaced. If the sensor is reporting correctly, the technician will suspect the engine oil pump, which necessitates removal of the oil pan, and physical inspection.
