Code P140B Cadillac Description

The Exhaust Gas Recirculation (EGR) valve is an electrically controlled valve that is controlled by the Engine Control Module (ECM). The EGR allows a specific amount of your exhaust gas into the intake manifold. This exhaust gas mixes with the intake air and cools the combustion process. The recirculated exhaust gas also prevents the formation of nitrogen oxides (NOx). The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the actual EGR flow is higher than a calibrated value for greater than 5 s.
