P1248 Fault Code: Understanding The Diesel Fuel Injector Pressure Control Valve Circuit
The P1248 fault code relates to the turbo boost pressure sensor in the intake manifold. This sensor measures the pressure created by the turbocharger and adjusts accordingly based on the accelerator pedal position and engine speed. The Powertrain Control Module (PCM) uses this information to diagnose the barometric pressure sensor and protect the engine from overboost.
The boost pressure sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit. The PCM supplies 5 volts to the sensor and provides a ground on the low reference circuit.
The sensor then sends a signal to the PCM based on the pressure changes. The PCM monitors the boost pressure sensor signal for any voltage outside of the normal range. It also calculates a predicted value for the sensor and compares it to the actual signal.
If there is a discrepancy, the P1248 fault code is triggered, indicating an issue with the turbo boost pressure sensor.
