How to Change a Car Oil Pressure Sensor

Most cars either have an oil pressure gauge or an oil pressure light that indicates when the oil pressure is in an optimum pressure range or when it might be too low. If the oil pressure sender fails, you can either read too low or not at all, and it’s a relatively simple procedure to swap it out.

You first have to locate the oil pressure sensor. In this case, it’s threaded into the side of the block right here. You remove the connector, which is usually a single wire from the sensor. Then you simply put a wrench on the Hex, back it out, put the new one in and tighten it up. Usually, it comes with a new seal. If it does not, you want to put either a Teflon paste or Teflon tape on the threads and then reconnect the wire and you should have a functioning oil pressure lighter gauge.
