1. Remove the engine bottom cover.
2. Drain the engine oil.
3. Remove bolts A, remove cover B and connector C of the engine oil level sensor.
Note. If the cover is damaged, replace it.
4. Remove bolts A, then remove engine oil level sensor B from oil pan C.
Note. To prevent damage to the oil pan and sensor mounting surface, do not use sharp tools when removing the sensor.
If you find damage to the sensor, replace it.
5. Clean the area around the mounting hole on the oil pan for the oil level sensor if there are traces of oil, dirt or grease.
Note. Do not scratch or damage the mounting surface of the sensor.
6. Perform sensor installation operations in the reverse order of removal, observing the following:
- use a new O-ring A and make sure it is not bent;
- clean any oil, dirt, or grease from the O-ring groove on sensor B, bolts C, and bolt holes D;
- be careful not to scratch the mounting surface of the sensor;
- do not allow oil to enter the connector E;
- make sure the O-ring surface F of the oil level sensor is 1.0mm±0.15mm from the sensor (from all sides) G.
7. Install the drain bolt and fill with engine oil to the maximum level.
Start the engine. Keep the speed of the crankshaft 3000 rpm./min (min-1) without load (in neutral gearbox) until the radiator fan turns on and let it idle for at least 10 minutes.
9. Check «ENGINE OIL LEVEL MONITOR CONDITION» (engine oil level monitoring) V «DATA LIST» (data list) with HDS.
- If a status message is displayed «ACTIVE» (actively), go to step 10.
- If «INACTIVE» (not active), install a new sensor, then go to step 7.
10. Switch off the ignition, wait 3 minutes, then measure the engine oil level. If necessary, adjust the oil level to the maximum.
11. Start the engine and let it idle for 5 minutes.
12. Check «ENGINE OIL LEVEL» (oil level) on the menu «DATA LIST» (data list) with HDS and record the level.
13. Stop the engine, leave the ignition switch in the «ON» (II) and wait 3 minutes.
14. Check «ENGINE OIL LEVEL» on the menu «DATA LIST» using HDS and compare with the level obtained fixed in point 12.
- If the level has changed by more than 2 mm, the engine oil level sensor is good.
- If the level has not changed more than 2 mm, install a new sensor and go to 6.
15. Check for oil leaks around the sensor.
- If there are no leaks, go to step 16.
- If you find leaks, repair them, then go to step 16.
16. Install cover A of the engine oil level sensor and tighten the bolts to the specified torque.
17. Install the bottom engine cover.
