Explanation: Pressure imbalances: When an EGR cooler fails, it can leak coolant into the exhaust system, which creates steam and disrupts the normal exhaust gas flow, leading to uneven pressure changes in the exhaust manifold.  EGR valve response: The exhaust pressure control valve (often part of the EGR system) relies on a specific pressure differential to regulate the flow of exhaust gas back into the engine. If the pressure in the exhaust manifold is significantly altered due to a failing EGR cooler, the valve may not function optimally.  Potential consequences: Reduced engine performance: Incorrect EGR flow due to pressure fluctuations can lead to reduced power and poor acceleration.  Increased emissions: Improper EGR function can result in higher emissions levels.  Check engine light: A failing EGR cooler often triggers a check engine light due to the engine's inability to maintain optimal operating parameters.  Key points to remember: While an EGR cooler failure directly impacts the coolant system, its effects can cascade to affect the exhaust pressure control valve due to the altered exhaust gas dynamics.  If you suspect an EGR cooler problem, it's crucial to have it inspected and repaired promptly to prevent further complications with other components like the exhaust pressure control valve.  The information that is above details why when the EGR cooler was recalled by mopar and then fixed is most likely the reason that caused my  sensor to fail.  The dealership where the recall repairs are being done is trying to charge me almost $1500.00 dollars to replace them even though they are directly related to the recall.
