95-2
Engine Fuel Filter Differential Pressure : Erratic, Intermittent, or Incorrect 95-2
Engine Fuel Filter Differential Pressure : Erratic, Intermittent, or Incorrect The filtered fuel pressure is greater than the unfiltered fuel pressure. Ensure that the sensor connectors are connected to the correct sensors. If an electrical problem with a sensor is suspected, refer to Troubleshooting, "Sensor Signal (Analog, Active) - Test" for information that is related to troubleshooting an electrical problem with the fuel pressure sensors.
99-2
Engine Oil Filter Differential Pressure Sensor : Erratic, Intermittent, or Incorrect 99-2
Engine Oil Filter Differential Pressure Sensor : Erratic, Intermittent, or Incorrect The filtered oil pressure is greater than the unfiltered oil pressure. Ensure that the sensor connectors are connected to the correct sensors. If an electrical problem with a sensor is suspected, refer to Troubleshooting, "Sensor Signal (Analog, Active) - Test" for information that is related to troubleshooting an electrical problem with the oil pressure sensors.
