But the bit we’re interested in is the EGR cooling system ...Because it doesn't work well, the engine has to drop the combustion temperature lower to avoid NOx production, through the use of EGR. However, low combustion temperature increases soot production (kills the DPF early and creates other problems), decreases fuel economy and power.ISM/ISX ECM Posted December 30, 2017 When the engine is overheated, carbon emissions increase and fuel economy decreases Irwin Miller, who helped Mr Symptoms of bad egr …EGR Valve Leaks Like many other engines with an EGR, the Cummins ISX is prone to typical EGR problems. Cummins ISX and Signature EGR engines deliver 600 ...Faulty fuel injectors: If your engine has faulty Cummins injectors, they can cause a return flow or drop in fuel pressure, which alters the amount of fuel reaching the engine. Faulty injector pump problems: Pumps directly affect the fuel pressure and injectors, and a faulty pump can do a lot of expensive damage.

Symptoms of a Bad or Failing EGR Pressure Feedback Sensor Common signs include engine performance issues like rough idle and decrease in power, failing an emissions test, and the Check Engine Light coming on. by Ed Ruelas on January 07, 2016 Exhaust and Emission System Inspection Cost Service Location SELECT YOUR VEHICLE $0.00Fuel smell. The NOx released from the tailpipe of your car is not only harmful but has a very pungent odour. Also, when the EGR valve is not working correctly, there is a chance that your engine may burn more fuel, which releases a lot of hydrocarbons. They mix with the added NOx and generate a dangerous mix of harmful gases.On the ISX, it most likely has to do with a leak in the EGR valve. This is a difficult problem to diagnose, but monitoring the coolant consumption can help. If you notice that it's using a larger amount of coolant than normal, it's probably worth investigating further.
