Oil Pressure Sensor

This procedure covers the removal and replacement of the oil pressure sensor on a 2011-2014 Ford F-150 with the 5.0L Coyote V8 engine.

Warnings

Tools required

Parts

• Oil pressure sensor × 1 — Motorcraft DY1167 or equivalent
• Thread sealant (Teflon tape or paste) × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Allow engine to cool completely if recently operated
3. Disconnect negative battery terminal to prevent false codes
4. Raise and support vehicle on jack stands for better access from below (optional but recommended)
5. Position oil drain pan below sensor location to catch residual oil

Procedure

1. 1

   Locate the oil pressure sensor
   From below the vehicle or through the wheel well area on the driver's side, locate the oil pressure sensor. It is mounted on the engine block above the oil filter housing, below the exhaust manifold. The sensor has a single electrical connector attached.
2. 2

   Disconnect electrical connector
   Press the locking tab on the electrical connector and pull it straight off the oil pressure sensor. Move the wiring harness aside to provide clear access to the sensor body.
3. 3

   Position drain pan
   Position the oil drain pan directly beneath the sensor. Approximately 0.5 to 1 quart of oil will drain when the sensor is removed, depending on engine oil level.
4. 4

   Remove old oil pressure sensor
   Using a 29mm deep socket or dedicated oil pressure sensor socket, turn the sensor counterclockwise to remove it from the engine block. Work quickly once loosened to minimize oil spillage. Allow residual oil to drain completely before proceeding.
   ⚠Do not use excessive force; if sensor is seized, apply penetrating oil and allow time to soak
5. 5

   Clean mounting threads
   Use a wire brush or clean shop towel to remove any old thread sealant, debris, or oil residue from the threaded hole in the engine block. Ensure threads are clean and undamaged.
6. 6

   Prepare new sensor
   Apply a thin layer of thread sealant (Teflon paste or 2-3 wraps of Teflon tape) to the threads of the new oil pressure sensor. Do not apply sealant to the first 1-2 threads to prevent contamination of the oil system.
7. 7

   Install new oil pressure sensor
   Thread the new oil pressure sensor into the engine block by hand to ensure proper thread engagement and prevent cross-threading. Once hand-tight, use the torque wrench and appropriate socket to tighten the sensor to specification.
   Torque spec

   Oil Pressure Sensor20 Nm (15 lb-ft)
8. 8

   Reconnect electrical connector
   Push the electrical connector onto the new oil pressure sensor until it clicks into place. Verify the locking tab is fully engaged and the connection is secure.
9. 9

   Check and top off engine oil
   Check the engine oil level using the dipstick. Add engine oil as necessary to bring the level back to the full mark, accounting for the oil lost during sensor removal.
   ℹ️Use Motorcraft 5W-20 Synthetic Blend oil to maintain proper oil specification
10. 10

    Reconnect battery and clear codes
    Reconnect the negative battery terminal. Start the engine and verify the oil pressure warning light extinguishes within 2-3 seconds. Use an OBD-II scanner to clear any stored fault codes related to the oil pressure sensor.

Reassembly

1. Lower vehicle from jack stands if raised
2. Dispose of any spilled oil properly according to local regulations
3. Wipe down any oil residue from the engine block and surrounding components

Verification

• Start the engine and verify the oil pressure warning light goes out immediately
• Allow engine to reach operating temperature and inspect sensor for any oil leaks
• Monitor oil pressure gauge (if equipped) to ensure normal readings: 25-75 PSI at idle when warm, higher at elevated RPM
• Use scan tool to verify oil pressure sensor is reading within normal parameters (typically 40-70 PSI at 2000 RPM warm)
• Recheck engine oil level after running engine and top off if necessary
