Fault code P00B7 is a generic OBD-II trouble code defined as “Engine Coolant Flow Low/Performance” . It is set when the vehicle’s Powertrain Control Module (PCM) detects that the flow of coolant through the engine’s cooling system is insufficient or not performing as expected .
P00B6 is a generic powertrain Diagnostic Trouble Code (DTC) that indicates the Powertrain Control Module (PCM) has detected an abnormal correlation between the signals from the radiator coolant temperature sensor and the engine coolant temperature (ECT) sensor . This code is frequently encountered on vehicles from manufacturers like Chevrolet, Chevy, and Vauxhall, but can appear on any OBD-II compliant vehicle with this sensor configuration.
