What You Need to Know About P0471 Code 6.7 Cummins
P0471 code 6.7 Cummins is an emissions-related fault code. It indicates that the Exhaust Gas Recirculation (EGR) system on a Cummins 6.7 liter diesel engine is not working properly and needs to be serviced or repaired. The EGR system is responsible for reducing emissions by recirculating some of the exhaust gases back into the combustion chamber to reduce the amount of nitrogen oxides (NOx) released into the atmosphere. A malfunction in this system can cause the engine to run rough and produce higher levels of NOx than normal, resulting in a failed emissions test. To fix this issue, the technician needs to inspect and repair any damaged components that are causing the EGR system to not work properly. This may include replacing sensors, cleaning passages, or replacing other parts of the EGR system.
