Resistance Inspection
NOTE:
- The low fuel pressure sensor/fuel temperature sensor cannot be removed as a single unit. When replacing the low fuel pressure sensor/fuel temperature sensor, replace it together with the high pressure fuel pump as a single unit.
- Disconnect the negative battery terminal. (Refer to NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)
- Remove the plug hole plate. (Refer to PLUG HOLE PLATE REMOVAL/INSTALLATION .)
- Disconnect the low fuel pressure sensor/fuel temperature sensor connector.
- Measure the resistance between low fuel pressure sensor/fuel temperature sensor terminals E and C.
