Engine Diagnostics

A mechanic at Briseno’s auto repair can diagnose engine problems by using a variety of methods, including:

1. Visual Inspection: The mechanic will inspect the engine and surrounding components for any obvious issues, such as leaks, loose parts, or damage.

2. Listening: The mechanic will listen for any unusual noises coming from the engine, which can indicate specific problems.

3. Computer Diagnostics: The mechanic will use a diagnostic scanner to connect to the engine control module (ECM) to retrieve diagnostic trouble codes (DTCs) and other information about the engine’s performance.

4. Test-driving the vehicle: The mechanic will take the vehicle for a test drive to replicate the problem and gather more information about the problem.

5. Pressure and temperature test: The mechanic will use various tools to check pressure and temperature of different system in the engine such as oil, coolant, transmission fluid, etc.

6. Compression test: The mechanic will perform a compression test to check the engine’s internal condition.

7. Removing and inspecting components: if the above methods do not reveal the problem, the mechanic may remove and inspect various components such as the spark plugs, fuel injectors, or sensors to find the source of the problem.

These are some of the common methods used by mechanics at Briseno’s auto repair to diagnose engine problems.
