Oil Pressure Sensor



Specific to:

Hyundai Tucson 2006-2008

The oil pressure sensor measures the amount of pressure generated from the output of the oil pump. If the oil pressure is too low, mechanical damage and scoring may occur.

Removal & Installation

Specific to:

Hyundai Tucson 2006-2008

Do not perform this procedure with the engine hot, wait until the engine is cool or cold.

  1. Before servicing the vehicle, refer to the Precautions Section.
  3. Turn the ignition OFF .
  5. Remove the oil pressure sensor electrical connector.
  7. Remove the oil pressure sensor.

To install:

  1. To install, reverse the removal procedure.
  3. Tighten the sensor to 16 ft. lbs. (22 Nm).


Specific to:

Hyundai Tucson 2006-2008

Before servicing any vehicle, please be sure to read the precautions section, which deals with personal safety, prevention of component damage, and important points to take into consideration when servicing a motor vehicle.

  1. With the vehicle on a level surface, allow adequate drain down time of 2-3 minutes and measure for a low oil level. Add the recommended grade engine oil and fill the crankcase until the oil level measures full on the oil level indicator.
  3. Run the engine, and verify low, or no oil pressure on the vehicle gage or light. Listen for a noisy valve train or a knocking noise.
  5. Inspect for the following:

    Oil diluted by moisture or unburned fuel mixtures
    Improper oil viscosity for the expected temperature
    Incorrect or malfunctioning oil pressure sender
    Incorrect or malfunctioning oil pressure gauge
    Plugged oil filter
    Malfunctioning oil bypass valve

  7. Remove the oil pressure sender or another engine block oil gallery plug.
  9. Install an oil pressure gauge and measure the engine oil pressure.
  11. Compare the readings to specifications.
  13. If the engine oil pressure is below specifications, inspect the engine for one or more of the following:

    Oil pump worn or dirty
    Oil pump-to-engine front cover bolts loose
    Oil pump screen loose, plugged, or damaged
    Oil pump screen O-ring seal missing or damaged
    Malfunctioning oil pump pressure regulator valve
    Excessive bearing clearance
    Cracked, porous, or restricted oil galleries
    Oil gallery plugs missing or incorrectly installed
    Broken lash adjusters

  15. Higher than recommended oil pressure may be caused by one or more of the following conditions:

    Worn or sticking oil pump pressure relief valve
    Plugged oil filter
    Improper viscosity oil

  17. If the oil pressure tests according to specification and the oil pressure sensor gives a faulty reading, replace the oil pressure sensor (switch) as necessary.
