Outstanding way of testing sig wires ! It is far more simple than Paul Danner's putting a 5k ohm resistor in series and is absolutely safe... Thank you for this vid and several of your other succinct vids . Thomas Jones, New Orleans, LA

My Mt2400 only puts out 3.7v. I understand it doesn't matter for this test, but why would my MT2400 output differently than yours? Any idea?

hi i have a 2009 ford fiesta 1.6 tdci,i was driving it last week with no problems,then out of the blue a cog light came on which i have been told is the pcm light,the car died and wouldnt start for around 5 mins,eventually got it running and got it home,a friend plugged it in and a p0698 code came up,he said it was throttle pedal,so replaced that also put a new fuel filter after a day or 2 same thing happend,it wouldnt start so i put a forscan on it turned the pcm light off and it started,after 2 hours cut out again so i unplugged egr and it run fine for 2 days then the light came on again even with the egr unplugged,it has no problem starting but once that pcm light comes on the car will not start until i plug forscan into it and clear the p0698 code,is there anyone out there who can help it says sensor reference voltage c circuit low additional fault symptom circuit voltage below threshold......thanks in advance,jon

What if you have an intermittent signal wire problem…can you just run a signal wire and connect it to the ecm to the crankshaft connector ?

You need to show exactly how you connected the ohmeter, you had t&e camera too close and could not see anything how was connected , you explained it well but couldn't figure out how was connected the ohmeter to signal

ahmed dokman unplug your sensor. Take your meter set it on diode mode. Take black lead and connect it to a good ground and take red lead and touch signal wire and watch your scan tool for response. 👍

but if the sig can handle a short to ground why do we worry about meters and test lights?the amerpage draw from a short is emensly more and yet that doesnt destroy the pcm?

I am not sure if I understand you question. Signal voltage can’t handle short to ground. It will be pulled down to 0 volts.

Unplug sensor and take test light connected it to ground and touch signal wire. If your test light lights up your signal wire is short to power

If your signal wire greater then 5v from (+) to input and (-) to battery ground, would you include that the pcm is done?
