Engine Oil Level Sensor Removal/Installation

1. Remove the splash shield.

1. Drain the engine oil.

1. Remove the bolts (A), the engine oil level sensor cover (B), and the engine oil level sensor connector (C).
   NOTE: If the cover is damaged, replace it.

1. Remove the bolts (A), then remove the engine oil level sensor (B) from the oil pan (C).
   NOTE:
   - To avoid damaging the oil pan and the sensor mounting surface, do not use sharp tools when removing the sensor.
   - If you find any damage at the oil level sensor, replace it.

1. Clean the surface around the engine oil level sensor mounting hole at the oil pan if there is oil, dirt or grease.
   NOTE: Do not make and scratch or damage at the engine oil level sensor mounting surface.

1. Install the parts in the reverse order of removal, noting these items:
   - Use a new O-ring (A), and make sure it is not twisted when you install it.
   - Remove any oil, dirt or grease from the O-ring groove on the sensor (B), the bolts (C), and the bolt holes (D).
   - Be careful not to scratch the sensor mounting surfaces.
   - Do not cover the sensor connector (E) with oil.
   - Make sure the oil level sensor O-ring surface (F) is 1.0 mm±0.15 mm from the sensor (all around) (G).

1. Install the engine oil drain bolt and refill the engine oil to maximum level.

1. Start the engine. Hold the engine speed at 3,000 rpm (min −1 ) without load (in neutral) until the radiator fan comes on, then let it idle for more than 10 minutes.

1. Check the ENGINE OIL LEVEL MONITOR CONDITION in the DATA LIST with the HDS.
   - If it is ACTIVE, go to Step 10 .
   - If it is INACTIVE, install a new sensor, then go to Step 7 .

1. Turn the ignition switch to LOCK (0), wait 3 minutes, then measure the engine oil level. If needed, adjust the engine oil to maximum level.

1. Start the engine, and let it idle for 5 minutes.

1. Check the ENGINE OIL LEVEL in the DATA LIST with the HDS and note it.

1. Stop the engine, leave the ignition switch to ON (II), and wait 3 minutes.

1. Check the ENGINE OIL LEVEL in the DATA LIST with the HDS, and compare it with the level you noted in Step 12 .
   - If the level changed more than 2 mm, the engine oil level sensor is OK.
   - If the level did not change more than 2 mm, install a new sensor, then go to Step 6 .

1. Check for oil leaks around the sensor.
   - If there are no leaks, go to Step 16 .
   - If you find a leak, repair it, then go to Step 16 .

1. Install the engine oil level sensor cover (A), and torque the bolts.

1. Install the splash shield.
