Oil pressure sensor not working?
My oil pressure constantly reads nothing. I recently purchased a 2000 ford ranger with a 4.0L V6. Well, it constantly reads nothing on oil pressure. The motor has no knock and runs smooth… Do you think it is just the sensor? The oil pumps probably wouldn't be out would it? The truck has 170000 miles on it.
It could be the sender. For many years Ford oil pressure gauges have actually been idiot lights with pointers - if the oil pressure sender is happy at all the meter reads center scale.
Probably just the sensor went out but before you do that, check the wire and make sure it's not shorted anywhere, then I would try just replacing the sensor.
- Would a faulty water pump, on a 04 Ford Freestar, cause the Fuel Rail Pressure Sensor to go bad? There's definite spray pattern on the underside of the hood from the water pump going. Could antifreeze have gotten into the fuel rail sensor and caused it to fault? Is it possible to clean the Fuel Rail Pressure sensor or any corrosion? Part is EXPENSIVE.
- Oil pressure - in my dashboard - CAR OIL CHANGE -? Hi i'm getting the below message in my dashboard. Mine is a 10 yrs old ford card LOW OIL PRESSURE. could the above be due to ENGINE OIL due to be replaced. Or oil gone old or bad. i jut recently changed oil - its a 5k miles synthetic oil.
- Oil pressure warning light? I have a 2003 Ford Focus 1.6 petrol. I have noticed that after I turn off the engine and then turn the ignition back on the oil pressure warning doesn't not come on immediately like the other lights such as the battery red light. It takes a few seconds before it comes on. The oil level is ok. Why is this?
- Car leaking oil, not sure if its from oil filter or transmission? So I have a 1998 Ford windstar that broke down because the transmission just basically gave up on it. Anyway, before it broke down we gave it an oil change and it wasn't leaking any oil. After the transmission gave up, a couple months afterwards, it starts to leak oil. Could this be from the transmission or the oil filter? By the way, I know absolutely nothing about cars.
