Engine Filtered Fuel Delivery Absolute Pressure : Data Drifted Low 460-21
Fuel Pressure Sensor - After Fuel Filter : Data Drifted Low The 5 VDC supply to the sensor has been lost.
The code is logged. The Electronic Control Module (ECM) supplies a regulated voltage of 5.0 0.2 VDC to the sensors.The supply voltage for the sensors is routed from the ECM to terminal 1 of each sensor connector. The sensor return for the sensors is routed from the ECM to terminal 2 of each sensor connector. The ECM provides short circuit protection for the internal power supply. A short circuit to the battery will not damage the internal power supply.Note: The sensors are not protected from overvoltage. A short from the supply line to the +Battery may damage the sensors. If any of the diagnostic codes are active, a sensor may have been damaged. Repair the sensor supply and check for any active sensor diagnostic codes to determine if a sensor has been damaged.

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Determine if a code is active or logged.
Codes
Result: A -3 or -4 code is active. Note which ECM is reporting the active code.
Proceed to Test Step 2.
Result: A -21 code is active.
Proceed to Test Step 3.
2. Check for a Failed Sensor
A. Connect Cat ET.
B. Disconnect a sensor on the affected sensor supply circuit.
C. Use Cat ET to monitor following:
- Active code changes to logged
D. Connect the affected sensor to the wiring harness.
E. Repeat Step B through Step D
