Well on my 86 5.0 cougar there is a sensor just forward and above from the oil filter on drivers side. it was leaking just under the nut below the 1 wire connector. what the sensor is i dunno exactly but i had the guy at the parts house look at it and grab one for me. I just did an oil/filter change and changed the sensor out. now every time i fire the car up the idiot light stays on constant lol what gives?!?
Wrong or bad sensor?
That is the oil light switch. It's not a sensor or sender. If he grabbed you one for a gauge instead of a light, it will be the wrong one.
or there's low pressure and the light works
ok... i just checked the part number from Niehoff. shows up Oil Pressure Gauge Sender, application for thunderbird 88-81 and cougar 88-85
guess i better get another one? or install an electric gauge?
