Description:

This error code, ECU 000157.02, occurs when the ECU receives invalid pressure information from the fuel rail pressure sensor. This may be due to sensor malfunction, faulty wiring, or issues within the sensor circuit.

Reaction:

The engine control system may exhibit erratic behavior such as power fluctuations or poor acceleration as it cannot accurately regulate fuel injection.

Recommendations:

• Inspect Pressure Sensor: Check the fuel rail pressure sensor for damage or connection issues.
• Test Sensor and Circuitry: Perform electrical tests to ensure the sensor and its circuitry are functioning properly.
• Replace Faulty Sensor: If the sensor is found to be defective, replace it to restore accurate fuel pressure readings.
• ECU Reset and System Test: Reset the ECU after repairs and test the vehicle to ensure that fuel pressure is correctly monitored and controlled.

Note:

Accurate fuel pressure data is crucial for efficient engine performance. Ensuring that the sensor and its connections are in good condition helps avoid performance issues.
