Oil pressure gauge

Hello,

If the vehicle runs as usual then it is likely just the sensor. It could also be a faulty wire to the sensor.

You might want to check to see if you are getting power to the sensor.

Another possibility is a faulty gauge.

I have attached the oil pressure sensor location diagram for your reference.

Please let me know of any questions.

Thank you.
