Cummins engines power most Class 8 semis on the I-80 corridor. When your Cummins throws a fault code or won't start, you need a mechanic who knows Cummins inside and out. We carry Cummins-specific diagnostic software and repair thousands of Cummins trucks every year. Call +1 308-270-3596 and we will diagnose and repair your truck on-site.
Cummins ISX and QSX engines. Fuel systems, emissions, air systems, electrical control — all diagnosed with factory Cummins tools.
We connect to Cummins factory diagnostic software. Read fault codes, live data, sensor readings, and pinpoint the root cause of the fault.
Selective Catalytic Reduction (SCR) system faults, DEF heater failures, sensor replacements. Many DEF faults are resolved on-site.
Fuel rail pressure, injector faults, fuel line leaks, and fuel filter service. Cummins fuel systems are high-pressure and demand precision.
Exhaust Gas Recirculation and Diesel Particulate Filter problems are common on high-mileage Cummins. We diagnose and repair both systems.
Cummins engines run multiple computers and sensors. We test wiring, connectors, and control module outputs.
Cummins overheating issues, water pump failures, coolant leaks, and thermostat replacement. Winter cold start issues in Nebraska.
Cummins engines are industry standard for Peterbilt, Freightliner, and Kenworth Class 8 trucks. The ISX platform powers most semis built in the last 15 years. Cummins engines are known for durability — they often run 500,000+ miles. But they are also complex. The ISX runs a Selective Catalytic Reduction (SCR) system that requires Diesel Exhaust Fluid (DEF). The DPF (Diesel Particulate Filter) regenerates regularly. Multiple sensors feed real-time data to the main engine control module.
On I-80 through Nebraska, a Cummins fault can leave a driver stranded. A DEF sensor fault triggers an out-of-service code. An EGR valve sticking cuts power. A fuel pressure sensor fault confuses the fuel system. Without diagnostic software, you are guessing. We have the tools and the knowledge to get your Cummins running again on the road.
Call +1 308-270-3596 and describe the fault code or how the truck is acting. We will come to you on I-80 and repair it.
We handle Cummins ISX, QSX, and other Class 8 Cummins engines. Most newer Peterbilt, Freightliner, and Kenworth tractors run Cummins. We carry diagnostic software and replacement parts for these engines.
Yes. DEF system faults — sensor failures, heater faults, SCR catalyst issues — often throw codes that take trucks out of service. We diagnose and repair many DEF faults roadside, including sensor replacement.
Cummins ISX engines commonly fail on fuel sensor faults, EGR valve sticking, and DPF problems. Heavy-duty use over I-80 puts stress on these systems. We carry the tools to diagnose all three.
Diagnostics and minor repairs typically $300–$800. Sensor replacement or fuel system work $500–$1,500. We give you a quote before work starts.
We handle diagnostic downloads and some flash updates. Complex reprogramming may require a shop, but many standard resets and updates can be done on-site.
