P128E Fault Code: Understanding The Description And Troubleshooting Steps
The P128E fault code is related to the fuel rail pressure in the engine.
The Engine Control Module (ECM) monitors the actual fuel rail pressure reported by the fuel rail pressure sensor and compares it to a programmed value. If the values are outside the calibrated range for a specific duration, the P128E code will be triggered. This code indicates a performance issue with the fuel rail pressure.
When this fault code is present, it means that there may be a problem with the fuel system, specifically with the fuel rail pressure. It is important to address this issue promptly to ensure proper engine performance and fuel efficiency.
A diagnostic scan tool can be used to further investigate the cause of the problem and determine the necessary repairs or adjustments needed to fix the fuel rail pressure performance.
