* PRESSURE LIMITING VALVE TEST
Possible Causes
PRESSURE LIMITING VALVE DIAGNOSTICS
Diagnostic Test
1.PRESSURE LIMITING VALVE
Using the scan tool, measure the rail pressure and determine if the rail pressure is excessive (above 185,000 kpa/
26,831 psi), if it is, troubleshoot for excessive rail pressure first.
Remove the banjo bolt from the pressure-limiting valve on the fuel rail.
Install fuel system test fitting (9013) into the pressure-limiting valve.
Attach one end of a fuel hose to the fuel fitting and put the other end of the fuel hose into a container.
Perform the tests listed below to determine if the pressure-limiting valve is leaking.
a. Operate the engine at idle and watch for fuel flow into the fuel container.
b. Operate the engine at idle and actuate the high pressure safety valve test with the scan tool. Watch for fuel flow
into the fuel container.
If fuel flows into the fuel container, replace the pressure-limiting valve. If fuel does not leak from the pressure-limiting
valve, the test is complete.
NOTE: do not drive the vehicle with any portion of this test kit installed.
