Engine Filtered Fuel Delivery Absolute Pressure : High - moderate severity (2) E096 (2)
High Fuel Pressure The code is logged.
The fuel pressure is above the trip point pressure. The probable causes of high fuel pressure
Fuel pressure sensor
Fuel lines
Fuel transfer pump
Fuel return pressure regulatorNote: High fuel pressure may cause high fuel temperatures. Troubleshoot a code for high fuel pressure before troubleshooting a code for high fuel temperature.

Troubleshooting Test Steps Values Results
1. Determine the Code
A. Connect Cat ET to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Determine if a diagnostic trouble code is present.
Diagnostic trouble code
Result: A E096 (2) or 5580-16 code is present.
Proceed to Test Step 2.
Result: A code other than E096 (2) or 5580-16 code is present.
Troubleshoot the code. Refer to the proper troubleshooting procedure.

2. Check the Fuel Pressure Sensor
A. Record the fuel pressure from Cat ET. Record the data in Table 5.
B. Remove the fuel pressure sensor (3).
C. Install an 8T-7860 Connector into the port of the pressure sensor (3).
D. Install the 110-6349 Fitting as onto the 8T-7860 Connector.
E. Install a 8T-0855 Pressure Gauge onto a 6V-3990 Coupler.
F. Install the 6V-3990 Coupler onto the 110-6349 Fitting as.
After the pressure sensor is removed, a code for low fuel pressure will become active. Reset all active codes and clear all logged codes by cycling the keyswitch to the Off position, after the sensor is reinstalled.
G. Record the fuel pressure on the pressure gauge. Record the data in Table 5.
Fuel pressure
Result: The gauge value of the fuel pressure is within 137 kPa (20 psi) of the fuel pressure reading shown in ET.
Proceed to Test Step 3.
Result: The gauge value of the fuel pressure is not within 137 kPa (20 psi) of the fuel pressure reading shown in ET.
Replace the pressure sensor. Reset all active codes and clear all logged codes by cycling the keyswitch to the Off position. Verify that the problem has been resolved.
If the problem is not resolved, proceed to Test Step 3.

3. Inspect the Fuel Supply Lines
A. Visually inspect the fuel lines between the primary filter base and the inlet to the cylinder head. Also, inspect the fuel cooler, if equipped. Inspect the fuel return line from the head to the fuel tank. Inspect the lines for restrictions, pinching, and swelling.
Restrictions, pinching, and swelling
Result: The fuel lines and the cooler (if equipped) are OK.
Proceed to Test Step 4.
Result: The fuel lines and the cooler (if equipped) are not OK.
Make the necessary repairs. Reset all active codes and clear all logged codes by cycling the keyswitch to the Off position. Verify that the problem has been resolved.
If the problem is not resolved, proceed to Test Step 4.
4. Replace the Return Fuel Pressure Regulator
A. Replace the fuel pressure regulator.
Fuel pressure regulator
Result: The regulator was replaced. Reset all active codes and clear all logged codes by cycling the keyswitch to the Off position. Verify that the problem is resolved.
If the problem is not resolved, proceed to Test Step 5.
5. Inspect the Relief Valve for the Fuel Transfer Pump
A. Inspect the relief valve for the transfer pump. The spring must move freely.
Relief valve
Result: The relief valve is stuck closed.
Replace the fuel transfer pump. Reset all active codes and clear all logged codes by cycling the keyswitch to the Off position. Verify that the problem has been resolved.
Result: The relief valve is OK.
Clean the relief valve and reinstall the relief valve. Reset all active codes and clear all logged codes by cycling the keyswitch to the Off position. Verify that the problem has been resolved.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
