What Is Diesel Engine Diagnostics?
Diesel engine diagnostics is the process of using advanced software and tools to read your engine’s internal data. This helps identify performance problems, sensor failures, and potential mechanical issues. Think of it as a health checkup for your truck’s engine.
With today’s modern diesel engines, there are dozens of sensors and computer systems monitoring everything from fuel pressure to exhaust temperatures. When something goes wrong, the engine control unit (ECU) stores a trouble code—and that’s where we come in.
Common Issues We Catch with Diesel Diagnostics
Our trained technicians at B&V Motor Service in San Antonio can detect problems like:
- Fuel system malfunctions (injectors, fuel pressure, filters)
- Turbocharger and boost pressure issues
- EGR and DPF system problems
- Faulty oxygen or NOx sensors

- Glow plug and cold start issues
- Electrical system and wiring faults
- Transmission-related trouble codes
Catching these problems early helps prevent unexpected breakdowns, costly roadside tows, or engine damage. That’s why so many truckers in San Antonio rely on us to keep their diesel engines running clean and efficient.
