How much does it cost to replace oil pressure sensor

A mechanic can help replace your oil pressure sensor to ensure your car can signal you if your oil pressure dips too low. You’ll need this service if your oil pressure sensor lights up your dashboard.

This low-cost fix, running between $130 and $200 depending on the make and model of your car, is like taking your vehicle’s blood pressure. The oil pressure sensor ensures your car’s engine receives proper oil flow.

Oil keeps your car running efficiently and smoothly—that’s why the car insurance super app Jerry wants you to know all about your oil pressure sensor light and what to do if it needs replacing.

What is an oil pressure sensor?

Because there is no way to visually measure that your car is pumping enough oil through your engine, an oil pressure sensor is your set of eyes beneath your car’s hood.

Your car’s computer uses an oil pressure sensor to measure the flow of oil in your engine. If your oil pressure drops too low, not enough oil is circulating through your engine. Without sufficient oil pressure, your engine may not properly cool itself, or the friction between unlubricated parts could do significant damage.

Newer makes and models of cars may have an oil pressure gauge that measures pressure in PSI. If your oil drops below standard PSI levels, your sensor may need to be checked.

A lit-up oil pressure light on the dashboard is a warning that your oil pressure is dangerously low. That said, there is no real way to visually inspect the condition of your oil pressure sensor. If the light comes on, it may be a sign that you need more oil—or it could indicate that your sensor isn’t working.

If your oil pressure light is still on after you’ve changed your oil, it’s likely your sensor is faulty. Take your car to a mechanic to diagnose the cause of the light.

How is an oil pressure sensor replaced?

Because most cars are computerized, an intricate job like replacing an oil pressure sensor should be done by a professional. Here’s what they will do:

  • The vehicle is raised on jack stands

  • The faulty oil pressure sensor is removed

  • A new oil pressure sensor is installed

  • The vehicle is started, and the oil pressure is checked

  • The vehicle is lowered and taken off the jack stands

  • The vehicle is road-tested to see that the oil pressure light doesn’t switch on again

An oil pressure sensor is a basic electrical switch designed to measure accurate, real-time pressure and send a warning signal to your car’s instrument panel. The replacement of this electrical component should restore accurate readings to your car’s dashboard.

How important is it to get an oil pressure sensor replacement

Your car must maintain proper oil pressure while the engine is running. It is just as crucial that your car’s oil pressure be constantly monitored.

Running your car if oil the pressure is too low can cause expensive damage to your engine. If your engine pressure comes on, call a trusted mechanic to check it out.

What is the Oil Pressure Sensor all about?

Oil is vital for your engine – you need enough oil to lubricate and reduce friction throughout the engine. There’s no way to visually determine how much oil is being pumped through your engine, so your car’s computer relies on the oil pressure sensor to determine the flow.The oil pressure sensor is a basic electrical switch that provides information to the instrument cluster’s oil pressure gauge with the accurate real-time pressure. When the pressure is too low, not enough oil is being pumped through the engine to lubricate and cool components. When pressure drops below a threshold set by the automaker, the engine oil light on the car’s dashboard illuminates, warning you that driving could be dangerous.

Keep in mind:

  • There is no way to visually determine the operating condition of your oil pressure sensor.
  • If the sensor fails, it is impossible to determine whether there is sufficient oil flow/pressure to lubricate and protect your engine.
  • If your oil pressure sensor fails, it should be replaced immediately.

How it's done:

  • The vehicle is raised and supported on jack stands and tire is removed
  • The defective oil pressure sensor is removed
  • The new oil pressure sensor is installed
  • The engine is started and oil pressure is checked then the vehicle is taken off the jack stands
  • The vehicle is road tested for proper operation

Our recommendation:

Your car’s oil pressure sensor is an electrical component, and can be subjected to a number of issues, including wiring damage. If you suspect damage to the sensor, or have noticed your oil light come on, have it inspected and diagnosed by one of our expert mechanics.

What common symptoms indicate you may need to replace the Oil Pressure Sensor?

  • Oil pressure light is on
  • Oil pressure light turns on and off (can indicate several potential problems)
  • Depending on your make and model, you may have an oil pressure gauge that displays pressure in PSI. Note any drops below normal operating pressure.

How important is this service?

It is absolutely vital that your engine oil pressure be constantly monitored for potentially dangerous conditions. If your oil pressure sensor isn’t working properly, it cannot do its job, and must be replaced. If your oil pressure light comes on, call one of our expert mechanics immediately (driving with the light on can potentially cause damage).
