Resistance Inspection

NOTE:
  • The engine oil temperature sensor and engine oil pressure sensor cannot be removed as a single unit. When replacing the engine oil temperature sensor or engine oil pressure sensor, replace the engine oil temperature sensor/engine oil pressure sensor.
  1. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION (US) .)
  2. Disconnect the engine oil temperature sensor/engine oil pressure sensor connector. (See ENGINE OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE SENSOR REMOVAL/INSTALLATION .)
  3. Measure the resistance between engine oil temperature sensor/engine oil pressure sensor terminals E and C.
