Multimeter reading on electrical plugs, do i have a short?

[andrei]

Up front, i am clueless in this department and don't have wiring diagram to dive into it. Saw video of someone diagnosing sensor issues and decided to poke around manual transmission sensor due to ongoing glitches.

This is a plug to gear position sensor, it has 3 ports.

With battery negative terminal disconnected, connector sprayed with electronic cleaner, i used multimeter to check the resistance in the wire plug.
Will reference to ports from point of view as Left, Middle, Right.

L + M = 7.8 ohm
L + R = 5.6
M + R = 2.2
M + L = 7.8

Checked sensor side, all OL.
Does reading indicate there is a short in wire plug?

Out of curiosity checked crank position sensor wire plug in the same order:
1.3
147.8
1.5
1.3

And fuel line sensor wire plug, but forgot to write down numbers. There was some reading, and no OL

For those of you who are fluent in these matters, do you see any red flags? Should i redo measuring in some other way?

No, the fact is your reading a data line to i would assume the ECU. 3 lines for a position sensor is generally a magnetic pickup. One would be power, the other would be ground and the other would be your sense line out. If its a true position type its almost the same either way the testing is the same. What you are reading right now is the ECU paths through your wiring at you cannot conclude you have a short at this time.


Looking for a short it would be best to disconnect the other end and perform the same test you have done at which time you should get O.L. at all connections. if you have any resistance at that point you could consider the posibility of a short, that is of course if its not piggybacking something else that hasn't been disconnected. Looking at the schematic could prove useful here.

Im reading your response with a "duhhh" moment. I have no clue about whats on other end of the wire, of course.
Thank you very much for explanation, ill revisit this effort again later after familiarizing with wiring diagram.
