P2496EGR Cooler Bypass Position Sensor Circuit Intermittent or Erratic Bank 1

P2496 means the engine computer has detected an intermittent or erratic signal from the EGR cooler bypass position sensor on bank 1, so it cannot trust the sensor's reported position. The exhaust gas recirculation (EGR) cooler bypass valve routes exhaust around the cooler to manage temperature, and a flaky position signal prevents the computer from confirming the valve is where it should be.
