P0192-FUEL PRESSURE SENSOR VOLTAGE TOO LOW (CONTINUED) 2. (F855) 5-VOLT SUPPLY AND (K915) RETURN CIRCUIT Turn the ignition off. Disconnect the Fuel Pressure sensor harness connector. NOTE: Check connectors - Clean/repair as necessary. Measure the voltage between the (F855) 5-volt supply and (K915) Is the voltage between 4.5 and 5.5 volts? Yes >> Go To 3 No >> Go To 4 3. FUEL PRESSURE SENSOR Reconnect the disconnected Fuel Pressure Sensor harness connector. While monitoring scan tool, disconnect the Fuel Pressure sensor harness connector. Does the DTC P0193 set? Yes >> Replace the Fuel Pressure Sensor. Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL). (Refer to 8 - ELECTRICAL/ELEC- No >> Go To 4 4. (F855) 5-VOLT SUPPLY CIRCUIT SHORTED TO (K915) RETURN CIRCUIT Turn the ignition off. Disconnect the ECM harness connectors. Disconnect the Fuel Pressure sensor harness connector. Check connectors - Clean/repair as necessary. Measure the resistance between the (F855) 5-volt supply circuit and Is the resistance greater than 100 K Ohms? Yes >> Go To 5 No >> Repair the shorted circuits. Perform POWERTRAIN VERIFICATION TEST VER - 1 9 - 1126 ENGINE - ELECTRICAL DIAGNOSTICS - DIESEL DR/DH |
