Hi there. The fuel pressure sensor could have failed, there could be a short or open circuit in the fuel pressure sensor, or there could be a poor electrical connection with the electrical connector. You would need to check the sensor ’B’ to see if it has resistance on it or if there is no resistance. If the sensor has resistance, then the wiring to the sensor would need to be checked for resistance. If you need further assistance with your check engine light being on, then seek out a professional, such as one from Your Mechanic, to help you.
