Oil Level Sensor

This procedure guides you through replacing the oil level sensor on a 2012-2017 Toyota Camry with a 2.5L I4 engine, which monitors engine oil level and alerts the driver to low oil conditions.

Warnings

Tools required

Parts

• Oil level sensor × 1 — Toyota OEM 89461-30020 or equivalent
• Oil level sensor O-ring × 1 — Usually included with sensor

Fluids

• Toyota Genuine 0W-20 — 0.5 qt

Preparation

1. Park vehicle on level surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. Allow engine to cool completely for at least 2 hours if recently driven
4. Raise front of vehicle using jack and support securely on jack stands
5. Remove front passenger side splash shield or undertray for better access (plastic clips and 10mm bolts)
6. Position oil drain pan beneath oil pan area
7. Have shop towels ready to catch oil spillage

Procedure

1. 1

   Locate the oil level sensor
   From underneath the vehicle, locate the oil level sensor on the driver's side of the oil pan, near the front. It is a cylindrical component with a single electrical connector protruding from it.
2. 2

   Disconnect the electrical connector
   Press the locking tab on the electrical connector and carefully pull it straight away from the oil level sensor. Clean any debris from around the connector area with a shop towel.
3. 3

   Position drain pan
   Position the oil drain pan directly below the oil level sensor. Expect approximately 0.25 to 0.5 quarts of oil to drain when the sensor is removed.
4. 4

   Remove the oil level sensor
   Using a 10mm socket, carefully remove the bolt securing the oil level sensor to the oil pan. Once the bolt is removed, pull the sensor straight out of the oil pan. Allow oil to drain into the pan.
   ⚠Do not twist or rock the sensor excessively as this may damage the oil pan opening
5. 5

   Clean the mounting surface
   Wipe the oil pan mounting surface clean with shop towels. Use a wire brush or parts cleaner if necessary to remove old oil residue or debris. Inspect the mounting hole for any damage or debris.
6. 6

   Inspect the new sensor
   Verify the new oil level sensor has a new O-ring installed. Lightly coat the O-ring with clean engine oil to ease installation and ensure a proper seal.
7. 7

   Install the new oil level sensor
   Insert the new oil level sensor straight into the oil pan opening, ensuring the O-ring seats properly. Hand-thread the mounting bolt to prevent cross-threading.
   Torque spec

   Oil Level Sensor15 Nm (11 lb-ft)
8. 8

   Torque the sensor mounting bolt
   Using a torque wrench, tighten the oil level sensor mounting bolt to 15.0 Nm (11.0 lb-ft). Do not over-torque as this can damage the sensor or oil pan threads.

9. 9

   Reconnect the electrical connector
   Push the electrical connector firmly onto the oil level sensor until you hear or feel a click, indicating it is fully seated and locked.
10. 10

    Check and top off engine oil
    Lower the vehicle temporarily to level ground. Check the engine oil level using the dipstick. Add Toyota Genuine 0W-20 oil as needed to bring level to the full mark, accounting for oil lost during sensor replacement (typically 0.25 to 0.5 quarts).

Reassembly

1. Reinstall the front passenger side splash shield or undertray using original clips and bolts
2. Remove jack stands and lower vehicle completely to ground
3. Dispose of any spilled oil according to local regulations

Verification

• Start the engine and allow it to idle for 2-3 minutes while monitoring for oil leaks around the sensor
• Turn off the engine and wait 5 minutes for oil to settle
• Check oil level again with dipstick and verify it is at the full mark
• Clear any diagnostic trouble codes related to oil level sensor using an OBD-II scanner if present
• Take a short test drive and verify that the oil level warning light does not illuminate on the dashboard
• After test drive, recheck for leaks around the sensor while engine is warm
