well i knew i had low oil pressure but when i tap into the odometer instrument diagnostics, the oil pressure reading is zero and doesnt move an inch.

i want to know how to source out where the fault is, i have a brand new pressure switch installed btw.

I'm a noob when it comes to electronics and need to know how to test the voltage/resistance/whatever and what readings i should get from the oil pressure connector/ ecu pin (which pin?)) etc

as i was playing around and didnt know what i was doing, i put black to an earth point and red to the connector and it gave 0.02 mV .. Am i even close??



also, is the only way to test a MAP sensor to backprobe the sensor with the car running?? thankss alot.

WITH THE OIL PRESSURE SWITCH IS IT A LONG BLACK ONE YOU HAVE FITTED OR A SHORT ONE AND WHAT KIND OF FALC HAVE YOU GOT

ITS IN THE SECTION UNDER HIS AVATAR WHERE YOU HAVE TYPED "FALCON ROO KILLER" FOR EXAMPLE

SPEAK LOUDER, I CANT HEAR YOU

I THINK TITS THE SHORT ONE.

Providing you have a Futura with no Oil gauge, then the Instrument cluster WILL only display 0.

You have an OIL Switch. Not a Sender Unit.

The diagnostics only shows variables on Fairmonts/XR/Police etc.

The reason the Cluster has the option is merely manufacturing and the feature is in there.
The Oil Switch only gives an ON/OFF reading for the idiot light, a sender gives resistance for the gauge and therefore the 1-9bar in the LCD will work.

I hope this explains it, as im pretty unstable atm!

perfectly,, thanks
