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.
  1. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION (US) .)
  2. Disconnect the low fuel pressure sensor/fuel temperature sensor connector. (See HIGH PRESSURE FUEL PUMP REMOVAL/INSTALLATION .)
  3. Measure the resistance between low fuel pressure sensor/fuel temperature sensor terminals E and C.
