First off what does that sensor do?
Is it to shut off fuel pump when oil pressure is lost?


And can I not use it?

 

You could splice the two wires together complete the circuit but lack of oil pressure would be a good fail safe that I wouldn't want to give up.

 

Yes, it's a safety to ensure that your engine stops running if you don't have any oil pressure.

And can I not use it?

Yes, but why? As leirch said, it's a good fail safe.

 

Thx for reply guys,
Yes its a great fail safe, but its one thats always in my way.
I have to tis the connector back to not get burned on my headers .
Also Ive had a rash of bad luck with torque converters first and now my engine is coming back out for the third time in a year .
im converting to a 406 and was not sure if its drilled there.

I dont really sweat it anyway,my eyes are always pegged on guages .do to my recent luck Im alway paranoid something is going.

 

cnat u put it any where that you can get oil pressure from

 

You don't need it at all. It is a redundant circuit that is not needed. Unplug it, start the car up and go cruising.

 

Hmm....my motor currently isn't reading oil temperature. Is the sensor next to the filter for temperature and the one behind the intake for pressure? My oil pressure gauge shows pressure, but my oil temp (on Auto X Ray) shows something like -48 degrees for oil temperature.

Not trying to steal this thread, just curious which sensor is pressure and which is temperature.

 

The one behind the intake is for pressure. The one at the filter is a backup for the fuel pump relay. If the fuel pump relay dies while the car is running, It will supply power to the fuel pump and the MAF relay to keep the car running. To test it, start the car and pull the fuel pressure relay out and the car will continue to run. Shut the car off and it will not restart until you put the fuel pressure relay back in.

There is no sensor to monitor oil temp.

 

The 730 ECM must have an optional input for oil temperature b/c it displays on my scan tool. Perhaps some other GM vehicles (not the F-Body) got a oil temp sensor with the 730 ECM?

 

Just because your scanner has a readout for it don't mean it's actualy there. I have a Snap-On scanner and an OTC Genisys and I don't recall ever seeing an oil temp readout for a 7730 on either of them. But the Genisys will display non existing parameters on alot of different cars with a value of N/A.

 

Swapmaster is correct, there is no oil temp for the 7730 F-body - it's a "curio" of your scan tool. I suspect your scan tool used the same display for the SD Y-body (Vette) 727 which is VERY SIMILAR to the F-body 7730. The SD Y-body does have an oil temp input to the ECM.

 

Thanks all.

 

Great... I stripped out the 1/4" square channel plug on my 'new' block at that port, so I'll be going without this sensor. Hopefully I'll survive a splice or two. If the oil pressure chokes, I have other issues at hand...

 

Just to make sure,
I do have to splice those together right?
I guess the sensor ads ground when the vehical has pressure?

 

Don't splice the sensor wires together. Just zip-tie them out of the way or clip them out of the harness. Hooking them together will run the fuel pump and energize the MAF relay at all times.

What it does is, the orange wire goes to power (+), the tan/white wire goes to the fuel pump (+), MAF energize (+), the ECM fuel pump signal (B2) and the fuel pump relay N/C which goes to your ALDL connector terminal G.

So hooking the wires together does the same thing as hooking power to the ALDL connector "G".

 

True. I can't comment on the MAF relay but I use this very sender to prime the fuel lines any time I have unhooked them. If you splice the two outer wires in the plug together the fuel pump will run any time the battery is hooked up.

I do this after I change fuel filters and stuff like that.

 

What's that other sensor right near there? I'm putting one back together and forgot what goes where, but there's a hole... The one just above the oil pressure switch...
