SPN 97 - FMI 3 (Fault Code: 428)
SPN97 FMI3
CODES:
Fault Code: 428
PID(P), SID(S): P097
SPN: 97
FMI: 3/3
Lamp: AMBER
SRT:
REASON: Water-in-Fuel Indicator Sensor Circuit - Voltage Above Normal or Shorted to High Source. High voltage detected at the water-infuel circuit.
EFFECT: None on performance. No water-in-fuel warning available.
Circuit Description:
The water-in-fuel sensor is attached to the fuel filter. The electronic control module (ECM) provides a 5 volt reference signal to the water-in-fuel sensor. When the water collected in the fuel filter covers the sensor probes, the water-in-fuel sensor pulls the 5 volt reference voltage to ground, indicating high water accumulation in the fuel filter.
Component Location:
The water-in-fuel sensor is integrated into the bottom of the OEM supplied suction fuel filter. The OEM supplied fuel filter is located on the intake side of the engine. Use the following procedure for a detailed component location view.
Conditions for Running the Diagnostics:
This diagnostic runs continuously when the keyswitch is in the ON position.
Conditions for Setting the Fault Codes:
The ECM detects that the sensor signal voltage is above 4.95-VDC for 1 second.
Action Taken When the Fault Code is Active:
• The ECM illuminates the amber CHECK ENGINE lamp immediately when the diagnostic runs and fails.
Conditions for Clearing the Fault Code:
The ECM will turn off the amber CHECK ENGINE light immediately after the diagnostic runs and passes.
Shop Talk:
Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe™ Online for applicable fixes to the calibration stored in the ECM. If necessary, calibrate the ECM.
Possible causes for this fault code include:
• Open return or signal circuit in the harness, connectors, or sensor
• Signal wire shorted to sensor supply or battery voltage.
