P0014 is a generic powertrain code, which means it covers all makes and models of vehicles. The code means that the exhaust gas recirculation (EGR) system is not working properly. The EGR system helps to reduce emissions by recirculating a portion of the exhaust back into the engine. If the system is not working properly, it can cause the engine to run too rich or too lean.

Users typically search for a solution by asking about:
