I have alreddy located that one with one (1) terminal, appearently there is anoder one with three (3) terminals accrding to parts catalogue

I am not sure where you are seeing this but the switch I posted runs to the engine control module.

 

This is a gasoline/petrol engine or it is diesel?

It's a gasoline/petrol engine.


Problem is,the op light stays on and i had the switch replaced.scanner read:


Op sensor/switch circuit hight input.

This is the correct switch, if you unplug it do you get the same code?

 

The switch runs to the computer which tells the instrument cluster to turn the light on so you may have a pinched wire or a faulty computer. Try unplugging the switch completely then lets check at the computer to see if the switch wire is grounded.

 

Let me know how much help you need with this

 

Thank you

The oil pressure is indicated low if the green/yellow wire is disconnected from ground and is indicated high if the wire is grounded.

 

Either you have high oil pressure or the wire is grounded or the computer is failing.

 

What oil is installed in the engine? Is it 5W-30 weight?. Is the filter correct?

 

Have you checked the oil pressure with a mechanical gauge? If it is within spec (4 psi at idle and 25 - 80 psi running depending on RPM) then check that the wire is not grounded and then the computer would have to be replaced if the wire is disconnected from the computer yet the reading is still high.

 

Let me know how I can help

 

Thank you
