EGR system faults can cause check-engine lights, poor performance, excessive soot, failed regens and engine derates. Problems can come from the EGR valve, cooler, sensors, wiring or other related engine controls. Proper diagnostics are critical to finding the actual cause instead of throwing parts at it.
If you're experiencing any of these symptoms, we can diagnose the EGR system to find the actual cause before replacing unnecessary parts.
Using dealer-level diagnostic software and testing, we can identify EGR system faults including failed valves, coolers, sensors, wiring and related engine control issues.
DPF problems are common on modern diesel engines and can cause check-engine lights, failed regens, reduced power, poor fuel economy and engine derates. 3K Calibrations provides DPF diagnostics, repair and custom tuning for medium- and heavy-duty diesel engines, including Cummins, Detroit Diesel, PACCAR, International, Isuzu, Hino and Caterpillar.
A DPF collects soot from the exhaust and periodically needs to regenerate to burn off the accumulated soot. Regeneration can happen automatically while driving, or a forced regeneration can be commanded using diagnostic software when conditions allow. Failed or frequent regens are often a sign of another engine or aftertreatment problem
Using dealer-level diagnostic software, we can diagnose DPF and aftertreatment faults including failed regens, excessive soot loading, differential pressure problems, temperature sensor faults and related engine or SCR system issues.
DEF and SCR system problems can cause warning lights, fault codes, poor performance and severe engine derates. Common issues include DEF quality faults, crystallization, failed NOx sensors, DEF pumps, dosing systems and SCR efficiency faults..
We provide EGR, DPF, SCR/DEF diagnostics, repair and tuning for medium- and heavy-duty diesel applications, including:
