This article will help you remove the oil pressure sensor electrical connector.
Working part-time as an electrical mechanic, I have had to remove the oil pressure sensor connector several times. Successful removal of the connector is a must before replacing a faulty sensor. In most cases, removing an oil pressure sensor connector is a simple task. However, the steps will differ depending on the car’s year, make, and model.
You may need to uninstall additional parts to access the sensor connector on some vehicles.
In General, to Remove the Oil Pressure Sensor Connector in Your Car, You Need To:
- Remove the Negative Battery Cable
- Remove the Oil Pressure Sensor Electrical Connector
- Use a Ratchet and An Oil Pressure Sensor Socket to Loosen the Sensor Connector
- Take the Oil Pressure Sensor out Of the Vehicle
I will cover more details in the following sections.
Steps to Disconnect Oil Pressure Sensor and Connect The Electrical Connector
Oil Pressure Sensor Replacement Tools and Equipment Required:
- Socket for oil pressure sensor
- Set of ratchets and sockets
- repair manual or database
- Wrench for torque
- Wheel restraints
Location of The Oil Pressure Sensor in a Car
The oil pressure sensor is typically located near the bottom of a cylinder head in a car engine block. It can, however, be attached to the cylinder head as well. It will be outfitted with a block connector and one or two wires.
Conduct a Preliminary Inspection
If your dashboard device indicates low oil pressure, you should inspect the engine oil level first. A low oil level can cause a loss of oil pressure and expensive engine damage.
Thoroughly check the oil pressure sensor or switch. Look for problems like damaged cables and poor connections. Check the engine oil pressure with a mechanical gauge to ensure no wires are damaged.
Checking Pressure Gauge with a Mechanical Gauge
This step eliminates the possibility of low oil pressure within the engine.
This is How You Can Do It
- Disconnect the oil pressure sensor (or switch) — detailed in the “How to remove oil pressure sensor connector” step below.
- Connect the mechanical gauge adapter to the engine.
- Connect the gauge to the adapter.
- Start the engine and write down the gauge reading.
If the gauge reads normally, the problem is with the oil pressure sensor, the dashboard instrumentation, or the sensor circuit.
Because oil pressure sensors are relatively cheap, most people choose to replace them at this point.
How to Remove the Oil Sensor Connector
Step 1. Remove the negative battery cable to make sure there is no current flowing through the vehicle.
Step 2. Disconnect the oil pressure sensor’s electrical connector.
Step 3. To loosen the sensor, use a ratchet and an oil pressure sensor socket. In some instances, you may be able to replace the specialized sensor socket with a regular socket or a wrench.
Step 4. Take the oil pressure sensor out of the vehicle.
How to Install a New Pressure Sensor
Procedure
Step 1. Check whether the new and old oil pressure sensors are the same design. (Autozone has a handy app to enter your make and model.
Step 2. Put the sensor into place.
With a torque wrench, tighten the sensor to the manufacturer’s specifications.
Step 3. Coat the threads of the oil pressure sensor with sealant — if the replacement sensor does not come with sealant pre-applied. Attach a new oil pressure sensor to the engine.
(Note: It’s important to use sealant so the unit does not leak, A good suggestion is using Permatex high temp Teflon thread sealant (white) to put some in the middle section of the tapered thread. Screw it in carefully and let it settle.)
Step 4. Reconnect the electrical connector for the oil pressure sensor.
Step 5. Reconnect the negative battery cable or wire.
Wrapping Up
You can remove your oil pressure sensor in a straightforward procedure outlined in this guide. However, if you are experiencing some technicalities, stop the repair and consult an expert to avoid the problem spreading.
