5.0 oil pressure switch????
<TABLE width=300 align=left border=0><TBODY><TR><TD>
</TD></TR></TBODY></TABLE> From the front of the car, look down the front of the engine, betwen the water pump and power steering pump. You'll see the down there. Just above the oil filter there's an indentation in the block. At the front of that indentation is a bracket with an electrical harness of some kind on it. Behind that bracket is a cream-colored cylindrical thing with a wire attached. That's the oil pressure sender
not sure if ya'll agreeded with where it was located but this is what i came up with for a 5.0

A knock sensor prevents spark knock by using a piezoelectric crystal to retard timing. A piezoelectric crystal develops voltage on its surface when pressure is applied to it (usually 300-500mV for automotive purposes). When this AC voltage signal is created the computer knows to retard the timing until the sensors signals that the knock has stopped. On some vehicles the computer will advance the timing on it's own until knock occurs, and then retard it back just slightly. A knock sensor can be tested by tapping on the intake or around the sensor with a metal object. Then use a timing light with the engine running on fast idle. There should be a decrease in ignition advance. If that doesn't happen then you need to see if the sensor is creating a voltage signal, if it is functioning then that would indicate a bad advance circuit.

That Knock Sensor looks like the one which is missing on my engine block.
Thanks for the picture!
Where can I get that part?
Would I only get it by Ford or by another part shop?

In April I am going to visit some relatives in California and I´d liketo take the chance to buy some parts for my Bronco especially the Knock Sensor.
I´ve never been in California before and so I have to search for some good and not to expensive truck partshops.
But if I can´t get it, I would let you know it!
