Thanks for the support.
I have low circuit error with code as P2127
And U3013

When I put 5kohm at pin 5 and 6 at the pedal harness, the low circuit changes to HIGH circuit, but if I remove it it goes back to low circuit.
I did same to pin 1 and 2 with the resistor connected I get HIGH circuit fault code but when I disconnect it goes to LOW circuit.
I also pin the 3 against 2 and it gave Low circuit, likewise to 5 and 4 also gave LOW circuit,
But when I remove all pin out I get LOW on all the D and E input
Please I need advise on this issue. Am suspecting the pedal..
I removed the pedal and tried to use dvom to read while it is being pressed, no change on the dvom, even though pedal was moved slowly to capture any reading..
I await to read soon
Thanks

are you saying the code changes here or just your ohm measurement? or what are you saying here please explain?

I did recheck the voltage and the earth on the APP harness, and realized that the GROUND for the E circuit does not flow when car start but when car is not started you get full earth of juicy signal, but when the get started and you
Check the earth line which is yellow and green, it reduces
So the shorted is coming from the pcm, but knowing well it is earth, I just connect earth wire to that line and BAAM, no more fault codes when car get started.

Wait, what? :huh: So, if you were to clear the codes KOEO and never start the engine, no codes would reset? But as soon as you start it up, it sets P2127?
Likewise, if you sweep the APP KOEO, it looks good. But sweep it KOER, it'll fail?
Not questioning your results, just gotta make sure I've got my head around this. :silly:

I would never have thought to look for this, lol. How did you figure out the ground was changing?

Ans-:
What I did was,
With my fluke dvom, a thought came into my spirit to to probe the 5 volt reference line and the earth direct to B- , so I set the fluke dial to Dc Volt, hock a wire to one tip of the probe extend it to Battery Negative (, then the positive tip of the probe goes direct to the 5 volt reference pin 6 wire, now I got the car ignition turn on, voltage read 5 volt, on the fluke, I start the car, it still constant 5, I said okay, now I probe the GROUND side of the sensor harness that is pin 4, and Connect the wire I made direct from the battery negative to Positive this time, key off engine off, I got 12 volts , ignition turn on still 12 volts but when I start the car, the voltage reduce to 4-9 volts with fluctuations readings between 4-9 volts, now I went to the battery check charging system all is well.. so there I begun to whisper by singing through the whispering, then a thought came back that, if so the negative suppose to be solid being supplied the pcm is not regulated, I giving that line should not harm the pcm, so I gave the line that is pin 4, direct earth and it work, pcm did not complained that that line has an outside connection made to it or did not even notice any fault code or error performance at all...
So Tyler, I hope my response may have answered your question.
Sorry for my English anyway, it’s not my tongue language.
