CaptainXL said:What a complete pile of UNengineered shit ! I have been driving with the sender unplugged for days and i have no warning lights or low pressure gauge. It shows everything fine at 40 psi. I would never know if my oil pressure got low.
Sparky said:I thought the switch was closed when there was enough oil pressure, and open when the pressure dropped below a set level? Is it really the other way around? That's so dumb... dumb x2 because it should be a sensor and not a switch in the first place.
Dshow said:They do this so they can detect an open circuit/broken wire when the TB is first key'd on.
the roadie said:I guarantee the switch in the I6 is a switch and the sensor in the V8 is a sensor. And the gauge not being at zero is a stepper motor needle issue only.
Very cool. 15 years ago, I programmed a PCM test system for testing Motorola units used in Fords. Had to sign a non-disclosure agreement on the Ford specific features, but a switch closure is handled very differently in the firmware than an analog sensor reading. Unless you can hack at a much deeper level than pdmforlessdoes, we're not going to end up with an I6 PCM with the ability to read a V8 sensor. But you knew that.CaptainXL said:I also like to program on the side and am curious if the a/d converter in the pcm is capable of using input from a variable pressure sensor.

IIRC, 2002 was the only year with a low oil level sensor.

LBB said:If I have no oil I should have no oil pressure I believe.
Does the systems warns me against losing all my oil?

CaptainXL said:Ok, after reading up a little more it looks like it doesn't ground to the block.
McGMT said:Almost as if something else on/in the engine is telling the PCM that there indeed is oil pressure somewhere...
