Diesel Diagnostics in Ogden, Utah

Accurate testing is the first step toward a reliable repair. Ogden Diesel Sales & Service, operated by Casper Diesel LLC, provides professional diesel diagnostics for commercial trucks, work trucks, fleets and diesel-powered equipment in Ogden and across Northern Utah.

Find the Cause Before Replacing Parts

A fault code points to a system, but it does not always identify the failed part. We combine scan-tool data with electrical, mechanical and visual testing to understand why the code appeared and what is causing the truck or equipment to lose power, derate, smoke, overheat or run poorly.

Bring us check-engine lights, intermittent electrical faults, hard starts, no-starts, communication issues, fuel and air problems, cooling concerns, DPF or DEF warnings and unexplained performance changes. Our goal is a clear diagnosis and a practical repair plan.

Diesel Diagnostic Services

Testing may include computer fault-code scans, live data review, wiring and connector checks, battery and charging-system tests, fuel and air-system evaluation, cooling-system pressure tests, emissions-system diagnostics and hands-on inspection of related components.

Trucks, Fleets and Equipment

We diagnose semi trucks, medium-duty commercial vehicles, work trucks, forklifts, yellow iron and other diesel equipment. Fleet customers can use scheduled diagnostic inspections to find developing problems before they interrupt routes or jobs.
